Description

TECHNICAL FIELD

[0001] The present invention relates to the field of musical instruments, and more particularly, to a single-handed playing fingering system for an electronic saxophone. BACKGROUND

[0002] An electronic saxophone is an electronic musical instrument that combines the features of a traditional wind instrument and an electronic music synthesizer. It can produce sound without the use of external amplification. The electronic saxophone is an electronic instrument that converts sound electronically. Its sound source can be a programmed sound source or a collected sound source. It allows the player to change the tone by simple key operation and can simulate the intensity of the breath of a musician. The electronic saxophone can simulate the tone of any musical instrument in the world, such as a clarinet, an oboe, a trumpet, a flute, a Chinese two-stringed fiddle, a Chinese lute, a violin, a guitar, a bass, etc., as well as any number of electronic synthesized tones. The electronic saxophone can be played in a way similar to traditional woodwind instruments, or in a way unique to the electronic saxophone, imitating various bowed string instruments, plucked string instruments, and percussion instruments, etc. The latter involves some complex techniques and requires various keys, knobs, etc. on the electronic saxophone for the player to manipulate.

[0003] A MIDI keyboard for controlling the pitch of an electronic saxophone in the field of music is a pitch (audio) input keyboard equivalent to a character input keyboard. It sends instruction information of different pitch requirements by various combinations of keys. All existing electronic saxophones require the player to use both hands to manipulate the MIDI keyboard to control the basic pitch.

[0004] Since the electronic saxophone can play the tone of any musical instrument in the world and a large number of electronic synthesized tones, the player must use different techniques to perform the appropriate style according to different tones during performance, especially for the various tones from original instruments, which require the electronic saxophone to have a series of functions to play the style of each instrument. However, all existing electronic saxophones in the world must be played with both hands to manipulate the pitch keyboard, and even if they have more functions, the player cannot easily and freely manipulate these functions because there is no extra hand available. SUMMARY

[0005] One main advantage of the present invention is to provide a single-handed playing fingering system for an electronic saxophone, wherein the pitch keyboard of the electronic saxophone only needs one hand to control the basic pitch, and the other hand is completely released to manipulate other functions.

[0006] Another advantage of the present invention is to provide a single-handed playing fingering system for an electronic saxophone, wherein the pitch keyboard includes front keys of operable pitches and side keys for controlling the pitch switching of upper and lower octaves, and the player can control the front keys and side keys of the pitch keyboard with one hand, allowing the player to operate with one hand.

[0007] Another advantage of the present application is to provide an electric saxophone one-hand playing fingering system, wherein the pitch keyboard is provided with four finger position areas, any one of which can cover at least one front key of the pitch keyboard, and the four fingers of the player correspond to the four finger position areas of the pitch keyboard, thus simplifying the operation difficulty of the player.

[0008] Another advantage of the present application is to provide an electric saxophone one-hand playing fingering system, wherein the pitch keyboard uses side key switching octave, freeing up the thumb position behind the body to allow the electric saxophone to have more function buttons designed at the position, thus facilitating the player to use the buttons to control more functions.

[0009] Another advantage of the present application is to provide an electric saxophone one-hand playing fingering system, wherein the pitch keyboard can be a left-hand keyboard or a right-hand keyboard, and the left and right two one-hand playing keyboards can be combined for use, thus improving the applicability of the pitch keyboard.

[0010] Another advantage of the present application is to provide an electric saxophone one-hand playing fingering system, wherein the pitch keyboard can be used alone or together with an additional keyboard, thus improving the expandability of the pitch keyboard.

[0011] Another advantage of the present application is to provide an electric saxophone one-hand playing fingering system, wherein the pitch keyboard is controlled by the electric saxophone one-hand playing fingering system, which is simple to operate and has high reliability.

[0012] Another advantage of the present application is to provide an electric saxophone one-hand playing fingering system, wherein the pitch keyboard uses side key switching octave, freeing up the thumb position behind the body to allow the electric saxophone to have more function buttons designed at the position, thus facilitating the player to use the buttons to control more functions, making the functions more abundant and the playing more convenient.

[0013] Another advantage of the present application is to provide an electric saxophone one-hand fingering system, wherein each note in the electric saxophone one-hand fingering system has at least three kinds of operation fingering, and some notes can have ten kinds of operation fingering, so that the player can select appropriate fingering according to the need of connecting notes before and after in playing, thus simplifying the finger movement and better avoiding fingering errors. Another advantage of the present application is to provide a one-hand playing fingering system, wherein the electric saxophone one-hand playing fingering system can reproduce each note in the major scale of thirteen degrees in the single-position sound range without starting the octave switching knob, and each note can have multiple different fingering available for selection.

[0014] Another advantage of the present application is to provide a single-hand playing fingering system, wherein the multi-finger method for one sound of the electric wind instrument single-hand playing fingering system makes the awkward jumping finger movement during playing become smooth, and the various and fast switching between sounds becomes easy.

[0015] Another advantage of the present application is to provide an electric wind instrument single-hand fingering system, wherein the fingering can be operated on the left-hand keyboard or the right-hand keyboard, and the left-hand and right-hand keyboards can be combined for use in parallel or vertically, improving the applicability of the pitch keyboard.

[0016] Another advantage of the present application is to provide an electric wind instrument single-hand playing fingering system, wherein the other hand can be used to operate the additional keyboard other than the pitch keyboard, reducing the difficulty of operating various functions of the electric wind instrument, such as "timbre switching", "transposition", "special sound effects", "automatic tremolo", "automatic glissando", "glissando operation", chord configuration, etc., greatly reducing the difficulty of playing.

[0017] Another advantage of the present application is to provide an electric wind instrument single-hand playing fingering system, wherein the other hand can be used to operate the additional keyboard other than the pitch keyboard, reducing the difficulty of operating various functions of the electric wind instrument, such as "timbre switching", "transposition", "special sound effects", "automatic tremolo", "automatic glissando", "glissando operation", chord configuration, etc., greatly reducing the difficulty of playing.

[0018] According to an aspect of the present application, an electric wind instrument single-hand playing fingering system capable of achieving the foregoing and other objects and advantages comprises:

[0019] a pitch key group, an octave switching key group, and a pitch control module, wherein the pitch key group comprises at least nine pitch keys, wherein different combinations of the pitch keys of the pitch key group form a fingering corresponding to different fingers, the pitch control module is based on each fingering corresponding to a pitch, and the octave switching key group is used to operate the switching of the upper and lower octaves of the pitch, so that the covered pitch range reaches five octaves plus one augmented sixth from Eb2 to C8.

[0020] According to an embodiment of the present application, the pitch key group comprises X key, 1 key, P key, 2 key, 3 key, 4 key, 5 key, 6 key, and 7 key.

[0021] According to an embodiment of the present application, the octave switching key group comprises three switching keys, namely N key, M key, and L key, wherein the switching keys of the octave switching key group switch the octaves corresponding to the pitch.

[0022] According to an embodiment of the present application, when the octave switching key group is not activated, each of the notes in the major scale of the 13 semitones in the single position sound range is formed by the fingering of the combination of the pitch keys of the pitch key group, and each note has one or more alternative fingerings.

[0023] According to an embodiment of the present application, the pitch control module sets different fingerings for the combination of the pitch keys of the pitch key group, and when the octave switching key group is not used to switch the position, the pitch control module pre-sets 22 different pitch notes to form a major scale of 13 semitones from Eb4 to C6.

[0024] According to an embodiment of the present application, the pitch control module combines 84 fingering modules in different forms, and covers 22 pitches of the major scale in the Eb4 to D6 sound range.

[0025] According to an embodiment of the present application, the pitch control module provides at least one fingering for each of the 22 notes in the major scale from Eb4 to C6 in the single position sound range, and 17 commonly used notes have multiple different fingerings.

[0026] According to an embodiment of the present application, the electric pipe single-hand fingering system has a first position area group, a second position area group, a third position area group, a fourth position area group, and a fifth position area group, and the switching keys of the octave switching key group are used to switch between the first position area group, the second position area group, the third position area group, the fourth position area group, and the fifth position area group.

[0027] According to an embodiment of the present application, the middle sound position area group is the third position area group in all the area groups, which is the area group without using any switching key to switch the octave; when the N key is activated, all the notes are raised by one octave; thereby forming a high sound fourth position area group; when the L key is activated, the notes are raised by two octaves; thereby forming a super high sound fifth position area group; when the N key and the M key are activated, the notes are lowered by one octave; thereby forming a low sound second position area group; when the M key is activated, the notes are lowered by two octaves; thereby forming a double low sound first position area group.

[0028] According to an embodiment of the present application, the basic fingerings of the five position area groups are the same, and the relationship between adjacent area groups is an octave relationship, and the octave switching between the position area groups is achieved by activating different switching keys.

[0029] According to an embodiment of the present application, the 5 key is a semitone lowering key, and the 6 key is a semitone raising key.

[0030] According to one embodiment of this application, the single-hand fingering system for playing an electronic wind instrument further comprises a first finger position area, a second finger position area, a third finger position area, and a fourth finger position area arranged sequentially from top to bottom, wherein the first finger position area covers the X key, the 1 key, and the P key of the key group; the second finger position area covers the P key and the 2 key; the third finger position area covers the 3 key; and the fourth finger position area covers the 4 key, the 5 key, the 6 key, and the 7 key.

[0051] It should be noted that the embodiments shown in the accompanying drawings are merely examples used to specifically and vividly explain and illustrate the concept of the present invention. They are not necessarily drawn to scale in terms of size and structure, nor do they constitute a limitation on the concept of the present invention.

[0052] The directional terms such as up, down, left, right, front, back, front, back, top, and bottom mentioned or possibly used in this specification are defined relative to the structures shown in the various accompanying drawings. They are relative concepts and may therefore vary depending on their location and usage. Therefore, these or other directional terms should not be interpreted as restrictive.

[0053] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0054] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0055] Refer to the accompanying drawings in this application specification. Figures 1A to 8 As shown, an electronic wind instrument and its pitch keyboard according to a first preferred embodiment of this application will be described in the following description. The electronic wind instrument includes an electronic wind instrument body 100 (not shown in the figure) and at least one pitch keyboard 200 disposed on the electronic wind instrument body 100, wherein the pitch keyboard 200 is used to control the basic pitch of the electronic wind instrument. In this preferred embodiment of the application, the pitch keyboard 200 is a pitch keyboard that can be operated with one hand, so that the performer can control the basic pitch with only one hand, while freeing the other hand to operate other functions.

[0056] It should be noted that in the prior art, because performers using both hands to operate the basic pitch keyboard do not have a spare hand to operate the numerous additional functions on the electronic wind instrument, many functions cannot function properly. In particular, the inability to quickly switch and perform real-time stunts forces performers to frequently pause during performance to make switching operations. The pitch keyboard 200 described in this preferred embodiment allows performers to easily and freely operate the pitch keyboard with only one hand, while the performer can use the other hand to specifically operate all functions other than the basic pitch.

[0057] The pitch keyboard 200 includes a keyboard body 10, a pitch key group 20 disposed on the front of the keyboard body 10, and an octave switching key group 30 disposed on the side of the keyboard body 10. The pitch key group 20 is used to control the basic pitch, and the octave switching key group 30 is used to control the switching between octaves up and down. The pitch key group 20 is located on the left or right side of the front of the keyboard body 10, and correspondingly, the octave switching key group 30 is located on the left or right side of the keyboard body 10, so that the player can operate both the pitch key group 20 and the octave switching key group 30 on the front of the keyboard body 10 with one hand.

[0058] Understandably, existing electronic wind instruments use the thumb to switch octaves via an "octave switching device" on the back of the instrument. However, the pitch keyboard 200 of this preferred embodiment uses side keys (i.e., the octave switching key group 30 located on the side of the keyboard body 10) to switch octaves. This frees up the player's thumb to operate other function keys located on the back of the instrument, making playing more convenient. In short, in this preferred embodiment, the tips of the player's four fingers (index, middle, ring, and little fingers) are used to operate the pitch key group 20 located on the front of the keyboard body 10, while the player's thumb extends to the back of the pitch keyboard 200. This allows the player to hold and operate the pitch keyboard 200 with one hand. The player's palm or other parts of the four fingers are used to operate the octave switching key group 30 located on the side of the keyboard body 10, thus requiring only one hand to operate while switching between octaves.

[0059] In this preferred embodiment of the application, the pitch key group 20 of the pitch keyboard 200 includes at least nine pitch keys 21. Different combinations of the pitch keys 21 in the pitch key group 20 form fingerings corresponding to different fingers, and each fingering corresponds to a pitch. As an example, in a specific example of this application, the pitch key group 20 includes nine pitch keys 21, namely X key 211, 1 key 212, P key 213, 2 key 214, 3 key 215, 4 key 216, 5 key 217, 6 key 218, and 7 key 219, respectively labeled "X", "1", "P", "2", "3", "4", "5", "6", and "7" in the figure. The combinations of the nine pitch keys 21 in the pitch key group 20 form different fingerings, and each fingering corresponds to a specific pitch. In short, in this application, the pitch key group 20 includes nine pitch keys 21 for controlling basic pitches.

[0060] Those skilled in the art will understand that the number of pitch keys 21 on the pitch keyboard is merely exemplary and not a limitation. Therefore, in another optional embodiment of this application, the number of pitch keys 21 in the pitch key group 20 can be 6, 7, 8, 10, or other numbers. Preferably, in this preferred embodiment of the application, the number of pitch keys 21 in the pitch key group 20 is 9.

[0061] The octave switching key group 30 includes three switching keys 31: N key 311, M key 312, and L key 313. The switching keys 31 of the octave switching key group 30 switch the pitch in the corresponding octave. It is worth noting that when the switching keys 31 are not used to switch octaves, the range of a single zone can reach an augmented thirteenth interval. The performer switches the pitch in different positions by operating the three switching keys 31 of the octave switching key group 30.

[0062] like Figure 2A and Figure 2B As shown, in this preferred embodiment of the present application, the pitch keyboard 200 has a first position group, a second position group, a third position group, a fourth position group, and a fifth position group, and the octave switching key group 30 can switch between the first position group, the second position group, the third position group, the fourth position group, and the fifth position group through the switching key 31.

[0063] Taking the middle register as an example, it ranges from Eb4 to C6; each note in the chromatic scale within each register's range can have multiple different fingerings. The middle register is the third register among all registers, and it is the register where no octave switching keys 31 are used; that is, the performer does not activate any of the switching keys 31 in the octave switching key group 30. Based on this, the performer can raise all notes by one octave by activating the N key 311, thus forming a high-pitched fourth register; the performer can raise by two octaves by activating the L key 313, thus forming a super-high-pitched fifth register; the performer can lower by one octave by activating the N key 311 and the M key 312, thus forming a low-pitched second register; and the performer can lower by two octaves by activating the M key 312, thus forming a double-low register. In other words, the performer can use the switching key 31 of the octave switching key group 30 to switch the entire keyboard through the five positions to reach five octaves from Eb2 to C8 plus an augmented sixth.

[0064] The pitch keyboard 200 further includes a pitch control module 40, wherein the pitch control module 40 is electrically connected to the pitch key group 20 and the octave switching key group 30, wherein the pitch control module 40 is used to control the notes corresponding to the fingerings formed by the combinations of the pitch keys 21 of the pitch key group 20, and to control the position groups corresponding to the switching keys 31 of the octave switching key group 30. In short, the pitch control module 40 forms fingerings corresponding to different fingers based on different combinations of the pitch keys 21 of the pitch key group 20, and each fingering corresponds to one pitch; and sets corresponding position groups based on the switching keys 31 of the octave switching key group 30. According to the correspondence between fingerings and pitches set by the pitch control module 40, in this preferred embodiment of the application, each pitch corresponds to at least one fingering (a combination of pitch keys), and one fingering corresponds to a unique pitch.

[0065] In this preferred embodiment of the application, the pitch control module 40 is used to preset each key of the pitch key group 20 and the octave switching key group 30, and to set the function of each group of keys formed by the pitch keys 21 and the switching keys 31 of the pitch key group 20, and allows for personalized settings.

[0066] The pitch control module 40 sets different fingerings for the combinations of the pitch keys 21 of the pitch key group 20. That is, different combinations of the pitch keys 21 of the pitch key group 20 form different "fingerings." Without using the octave switching key group 30 to switch positions (i.e., single-position), the pitch control module 40 presets 22 different pitches to form a semitone scale covering a major thirteenth interval from Eb4 to C6. The pitch control module 40 assigns at least one fingering to each of the 22 notes in the semitone scale from Eb4 to C6 within the single-position range, and 17 of the most commonly used notes can have multiple different fingerings.

[0067] In this application, the first position group is the group that enables the side button "M", and is called the "double bass group"; the second position group is the group that enables both the side buttons "N" and "M", and is called the "bass group"; the third position group is the group that does not enable any side buttons, and is called the "midrange group"; the fourth position group is the group that enables the side button "N", and is called the "treble group"; the fifth position group is the group that enables the side button "L", and is called the "super treble group"; according to the design of the above five position groups, the range has covered five octaves plus one augmented sixth.

[0068] It is worth mentioning that, in this application, the use or non-use of any of the switching keys 31 in the octave switching key group 30 does not affect the basic fingering formed by the combination of the pitch keys 21 in the pitch key group 20. The pitch keyboard can be a left-handed keyboard or a right-handed keyboard.

[0069] like Figure 1A and Figure 1B As shown, the pitch keyboard 200 further comprises a first finger position area 201, a second finger position area 202, a third finger position area 203, and a fourth finger position area 204 arranged sequentially from top to bottom. The first finger position area 201 covers the X key 211, the 1 key 212, and the P key 213 of the key group 20; the second finger position area 202 covers the P key 213 and the 2 key 214; the third finger position area 203 covers the 3 key 215; and the fourth finger position area 204 covers the 4 key 216, the 5 key 217, the 6 key 218, and the 7 key 219. The player's index finger corresponds to the first finger position area 201, the middle finger to the second finger position area 202, the ring finger to the third finger position area 203, and the little finger to the fourth finger position area 204 of the pitch keyboard 200. It should be noted that the positional relationship between the performer's fingers and the various finger positions is not fixed. Performers can move their fingers to other positions according to their own preferences and playing habits.

[0070] As shown in the diagram, it should be noted that, following the natural arrangement and division of labor among human fingers, the nine pitch keys on the front of the keyboard for single-handed playing are divided into four finger positions: the first finger position 201, the second finger position 202, the third finger position 203, and the fourth finger position 204. The first finger position 201 includes the keys "X", "1", and "P", controlled by the index finger; the second finger position 202 includes the keys "2" and "P", with the "P" key being the same as the "P" key in the index finger position, also controlled by the index finger; the third finger position 203 includes the key "3", controlled by the ring finger; and the fourth finger position 204 includes the keys "4", "5", "6", and "7", controlled by the little finger.

[0071] Understandably, the index finger has a wider range of opening and closing and greater flexibility than the middle and ring fingers. Using the index finger to correspond to the first finger position area 201 makes it highly operable and reduces the possibility of misoperation. Meanwhile, the ring finger, which corresponds to the third finger position area 203 that only covers one key, does not need to move up and down, thus reducing misoperation.

[0072] It is worth mentioning that, in this preferred embodiment of the application, the first finger position area 201 and the second finger position area 202 cover the P key 213. This means that both the performer's index and middle fingers can be used to operate the P key 213. The user can choose to use either the index or middle finger to operate the P key 213 according to the fingering for a specific pitch and the rhythmic changes between preceding and following notes. When the performer needs to use a specific fingering, such as simultaneously operating the X key 211 and the P key 213, and cannot use the same finger, the performer can use the index finger to operate the X key 211 and move the middle finger up to the P key 213 to complete the operation of the specific note.

[0073] The X key 211, the I key 212, and the P key 213 located in the first finger position area 201 are arranged side-by-side adjacent to each other along a direction suitable for finger sliding. For example, the X key 211, the I key 212, and the P key 213 can be arranged side-by-side along a vertical (or horizontal) direction, making it convenient for the player to move between the X key 211 and the I key 212, or between the I key 212 and the P key 213, when switching fingerings, thereby improving the smoothness of the switching. The P key 213 and the 2 key 214 located in the second finger position area 201 are arranged side-by-side adjacent to each other along a direction suitable for finger sliding. For example, the P key 213 and the 2 key 214 can be arranged side-by-side along a vertical (or horizontal) direction, making it convenient for the player to move between the P key 213 and the 2 key 214, when switching fingerings.

[0074] The 3rd key 215 covered by the third finger position area 203 is located between the 2nd key 214 of the second finger position area 202 and the 4th key 216 of the fourth finger position area 204. The 3rd key 215 covered by the third finger position area 203 and the 4th key 216, 5th key 217, 6th key 218, and 7th key 219 covered by the fourth finger position area 204 are tilted from top to bottom and to the side. That is, the area covered by the third finger position area 203 and the fourth finger position area 204 is closer to the outside than the first finger position area 201 and the second finger position area 202. This makes it convenient for the player to use the ring finger and little finger to operate the pitch keys located in the third finger position area 203 and the fourth finger position area 204.

[0075] The area covered by the fourth finger position area 204 extends outwards at an angle from top to bottom. The player's little finger can easily and conveniently control the 4 key 216, the 5 key 217, the 6 key 218, and the 7 key 219 located in the fourth finger position area 204. When the player's fingers correspond to each finger position area, their palm (excluding the fingertips) will cover the octave switching key group 30, making it convenient for the operator to control the switching key 31 of the octave switching key group 30 with their palm (excluding the fingertips).

[0076] It is worth mentioning that the pitch keyboard of this preferred embodiment has a matching playing fingering. It can be said that the pitch keyboard is specifically designed for a one-handed playing fingering system, or that the one-handed playing fingering system is based on the pitch keyboard. It is understood that the pitch keyboard is formed according to the shape of the human hand. Since humans have five fingers, the index finger is the easiest to control, followed by the little finger, so the key sequence on a keyboard is largely similar across all humans. Because humans have two hands, all keyboards are operated with two hands. Depending on the shape of the instrument, the arrangement of the keys can be linear, curved, or even zigzag; this application does not impose any limitations on this. The pitch keyboard of this preferred embodiment allows the performer to operate it with only one hand.

[0077] The pitch keyboard 200 further includes a palm area 205, which is located outside each finger area and covers each of the switching keys 31 of the octave switching key group 30. The palm area 205 of the pitch keyboard 200 corresponds to the performer's palm (excluding the fingertips). The switching keys 31 of the octave switching key group 30 are located outside the pitch keys 21 of the pitch key group 20, where each of the pitch keys 21 of the pitch key group 20 is covered by each finger area, suitable for operation by the performer's four fingers (index, middle, ring, and little fingers); the switching keys 31 of the octave switching key group 30 are covered by the palm area 205, suitable for the performer to operate and control each of the switching keys 31 of the octave switching key group 30 using their palm (excluding the fingertips).

[0078] The N key 311, M key 312, and L key 313 of the switching keys 31 are located in the palm area 205 of the pitch keyboard 200, or each of the switching keys 31 is covered by the palm area 205, wherein the player's palm (excluding the fingertips), such as the first or second joint (where the third joint is the fingertip) of the index, middle, or ring finger, can operate the switching keys 31. The N key 311 and M key 312 of the switching keys 31 are spaced apart in the vertical direction, which facilitates the player to operate the N key 311 or the M key 312 individually, or to operate the N key 311 and the M key 312 simultaneously. The L key 313 is located on the back of the N key 311 and the M key 312, and the L key 313 is located in the middle position between the N key 311 and the M key 312, which facilitates the player to operate the L key 313 without touching the N key 311 and the M key 312.

[0079] It is worth mentioning that, in this preferred embodiment of the application, while the key arrangement of the pitch keys 21 of the pitch key group 20 and the switching keys 31 of the octave switching key group 30 remains basically unchanged, the size of the keyboard can be scaled to accommodate players of different ages and types.

[0080] like Figure 3 As shown, in this preferred embodiment of the application, the pitch keyboard 200 can be implemented as a left keyboard 210, i.e., a left-handed keyboard suitable for use with the left hand; or the pitch keyboard 200 can be implemented as a right keyboard 220, i.e., a right-handed keyboard suitable for use with the right hand. When the pitch keyboard 200 is a left keyboard, the octave switching key group 30 of the pitch keyboard 200 is located on the left side of the keyboard body 10; when the pitch keyboard 200 is a right keyboard, the octave switching key group 30 of the pitch keyboard 200 is located on the right side of the keyboard body 10. Depending on individual preference and existing knowledge of other instruments, the pitch keyboard for playing an electronic wind instrument with one hand can be used with either the right or left hand. The keyboard for the left hand is a mirror image of the keyboard for the right hand.

[0081] like Figure 4A and Figure 4BAs shown, in a preferred embodiment of this application, the left keyboard 210 and the right keyboard 220 of the pitch keyboard 200 can be combined for use, that is, the left keyboard 210 and the right keyboard 220 of the pitch keyboard 200 are combined into a combined keyboard suitable for a performer to play with both hands. The left keyboard 210 and the right keyboard 220 of the pitch keyboard 200 are combined in a horizontally connected manner to form a combined keyboard, wherein the left keyboard 210 and the right keyboard 220 are mirror-symmetrical from left to right. Optionally, in another optional embodiment of this application, the left keyboard 210 and the right keyboard 220 of the pitch keyboard 200 are combined in a vertically connected manner to form a combined keyboard, wherein the left keyboard 210 and the right keyboard 220 are connected vertically. It is worth mentioning that, in this application, the left keyboard 210 and the right keyboard 220 of the pitch keyboard 200 are connected to the pitch control module 40, and the pitch control module 40 controls the pitch emitted by the left keyboard 210 and the right keyboard 220, that is, controls the left keyboard 210 and the right keyboard 220 to be used as a combination keyboard.

[0082] It is understood that the combination keyboard can be used for multi-part playing with both hands, or for ordinary two-hand playing through custom settings. The pitch control module 40 sets one of the two keyboards (such as the left keyboard 210 or the right keyboard 220) as a function-inspired keyboard, where each of the function-inspired keyboards can become a function-inspired key for various functions.

[0083] The pitch control module 40 is equipped with a combination keyboard that can be used for two-part playing with both hands; the hands can play different melodies and different timbres. It is worth mentioning that the pitch control module 40 can be customized for ordinary two-handed playing; or, using the custom mode, one of the two keyboards can be set as a function and special effects keyboard, so that each key can be used to operate one or more functions.

[0084] like Figure 5 As shown, the wind instrument further includes an additional keyboard 300, which can be disposed on the wind instrument body 100 and can be connected to the left keyboard 210 or the right keyboard 220 of the pitch keyboard 200 to form a combined keyboard. The additional keyboard 300 is used by the other hand to operate functions other than those of the basic pitch.

[0085] As shown in the figure, the auxiliary keyboard 300 includes a bass-bayon area 310, which resembles the area of ​​an accordion bass keyboard. The bass-bayon area 310 of the auxiliary keyboard 300 can be used as both a bass accompaniment keyboard and a bayan pitch keyboard. The bass-bayon area 310 contains numerous keys, each of which can be customized to have an additional function, such as transposition, changing timbre, adding slides, adding various chords, controlling pitch bend, activating automatic slides, and activating vibrato, guttural sounds, flutter tonguing, staccato, plucking, tremolo, and strumming, etc.

[0086] The bass bayan section 310 of the auxiliary keyboard 300 can also be used as a regular electronic keyboard. In this case, its sound production can be controlled by the player's breath or by other methods. Since the bass bayan section 310 of the auxiliary keyboard 300 can play melodies independently, it can be used alone or in conjunction with the pitch keyboard 200.

[0087] According to another aspect of this application, this application further provides a single-finger fingering system for an electronic wind instrument adapted to the pitch keyboard 200, wherein the single-finger fingering system for the electronic wind instrument includes a pitch key group 20, an octave switching key group 30, and a pitch control module 40, wherein the pitch control module 40 of the single-finger fingering system for the electronic wind instrument sets different notes based on the combination of the pitch key group 20 and the octave switching key group 30, so that the covered range reaches five octaves plus one augmented sixth from Eb2 to C8.

[0088] In the preferred embodiment of the electronic wind instrument single-finger technique system of this application, the pitch control module 40 is provided with a variety of fingering modules corresponding to different pitches. One of the modules corresponds to a fingering on the pitch keyboard 200. The pitch control module 40 is provided with 84 fingering modules, that is, the pitch control module 40 sets 84 fingerings. The fingering corresponding to each fingering module corresponds to a pitch, and each pitch has one or more fingerings.

[0089] In other words, in this preferred embodiment of the application, the pitch control module 40 is based on the nine pitch keys of the pitch keyboard 200, which are combined in different ways to form 84 different fingering combinations. These combinations can be operated by the index, middle, ring, and little fingers. The 84 fingering modules set by the pitch control module 40 cover 22 "pitches" in the chromatic scale from Eb4 to D6. Each "fingering module" corresponds to one "pitch," and this module becomes the "fingering" for that pitch. Each "pitch" can have one or more corresponding "fingering modules," that is, it can have one or more "fingerings." It is understood that the interface of the pitch keyboard 200 is connected to the MIDI interface of the electronic music chip, and the pitch control module 40 generates the corresponding pitch according to the fingering instructions on the keyboard.

[0090] It should be noted that in this preferred embodiment of the application, four finger positions are used to control 84 fingering modules, forming 22 notes of the chromatic scale from Eb4 to D6, which are the basic pitches of the keyboard for single-handed playing of an electric wind instrument, and also the basic position group of the fingering for single-handed playing of an electric wind instrument.

[0091] By using the side keys "L", "M", and "N", the overall pitch of the basic position group can be raised or lowered by one or more octaves. Using the side key "M" lowers the overall pitch of the position group by two octaves, forming the "First Position Group", also known as the "Double Bass Position Group"; using the side keys "M+N" lowers the overall pitch of the position group by one octave, forming the "Second Position Group", also known as the "Bass Position Group"; the group without using any side keys is the "Third Position Group", also known as the "Middle Position Group"; using the side key "N" raises the overall pitch of the position group by one octave, forming the "Fourth Position Group", also known as the "Double Bass Position Group"; using the side key "M" raises the overall pitch of the position group by two octaves, forming the "Fifth Position Group", also known as the "Ultra-Treble Position Group".

[0092] It should be noted that the fingering provided by the single-finger fingering system for the electronic wind instrument described in this application, combined with the different pitch keys 21 of the pitch key group 20, that is, when the performer operates the corresponding pitch keys 21 of the pitch key group 20 according to a specific fingering, the electronic wind instrument can trigger that specific pitch.

[0093] The pitch control module 40 of the single-finger fingering system for the electronic wind instrument provides at least one fingering for each pitch. When the octave switching key group 30 is not used to switch octaves, the range of a single zone can reach an interval of an augmented thirteenth. Taking the alto position zone as an example, it ranges from Eb4 to C6; each note in the chromatic scale within the range of each zone can have multiple different fingerings.

[0094] In this preferred embodiment of the application, the pitch key group 20 includes at least nine pitch keys 21, wherein different combinations of the pitch keys 21 in the pitch key group 20 form fingerings corresponding to different fingers. Different fingerings are formed based on the different combinations of the pitch keys 21 in the pitch key group 20 set by the single-finger fingering system for the electronic wind instrument, with each fingering corresponding to a pitch.

[0095] As an example, in a specific example of this application, the pitch key group 20 includes nine pitch keys 21, namely X key 211, 1 key 212, P key 213, 2 key 214, 3 key 215, 4 key 216, 5 key 217, 6 key 218, and 7 key 219, which are labeled X, 1, P, 2, 3, 4, 5, 6, and 7 respectively in the figure. The combinations of the nine pitch keys 21 of the pitch key group 20 form different fingerings, and each fingering has a corresponding pitch.

[0096] Those skilled in the art will understand that the number of pitch keys 21 in the pitch key group 20 is merely exemplary and not a limitation. Therefore, in another optional embodiment of this application, the number of pitch keys 21 in the pitch key group 20 can be 6, 7, 8, 10, or other numbers. Preferably, in this preferred embodiment of the application, the number of pitch keys 21 in the pitch key group 20 is 9.

[0097] In the single-finger fingering system for the electronic wind instrument according to this preferred embodiment of the present application, when the octave switching key group 30 is not switched, the fingering group formed by each pitch key 21 of the pitch key group 20 corresponds to a position group of a range. The corresponding position group is switched by the octave switching key group 30. In the single-finger fingering system for the electronic wind instrument according to this preferred embodiment of the present application, when the octave switching position is not activated, the fingering formed by the combination of each pitch key 21 of the pitch key group 20 reproduces each note in the chromatic scale of the augmented thirteenth degree in the single position range, and each note has one or more different fingerings that can be selected and used.

[0098] It is worth mentioning that the electronic wind instrument single-finger fingering system can be used for single-handed operation with the left hand, single-handed operation with the right hand, or operation with both hands. The fingering for right-handed keyboard operation is exactly the same mirror-flipped fingering as the fingering for left-handed keyboard operation.

[0099] The octave switching key group 30 includes three switching keys 31: N key 311, M key 312, and L key 313. The switching keys 31 of the octave switching key group 30 switch the pitch in the corresponding octave. It is worth noting that when the switching keys 31 are not used to switch octaves, the range of a single position group can reach an augmented thirteenth interval. The performer switches the pitch in different position groups by operating the three switching keys 31 of the octave switching key group 30.

[0100] like Figure 2A and Figure 2B As shown, in this preferred embodiment of the present application, the single-finger fingering system for the electric wind instrument has a first position group, a second position group, a third position group, a fourth position group, and a fifth position group, and can be switched between the first position group, the second position group, the third position group, the fourth position group, and the fifth position group by means of the switching key 31 of the octave switching key group 30.

[0101] Taking the middle register as an example, it ranges from Eb4 to C6. Each note in the chromatic scale within each register has at least one fingering, with at least some pitches having two or more different fingerings. The middle register is the third register in the overall register sequence, and it is the register where no octave switching keys 31 are used; that is, the performer does not activate any of the switching keys 31 in the octave switching key group 30. Based on this, the performer can raise all notes by one octave by activating the N key 311, thus forming a high-pitched fourth register; the performer can raise by two octaves by activating the L key 313, thus forming a super-high-pitched fifth register; the performer can lower by one octave by activating the N key 311 and the M key 312, thus forming a low-pitched second register; and the performer can lower by two octaves by activating the M key 312, thus forming a double-low register. In other words, the performer can use the switching key 31 of the octave switching key group 30 to switch the entire keyboard through the five positions to reach five octaves from Eb2 to C8 plus an augmented sixth.

[0102] It is worth mentioning that in the single-finger fingering system of the electric wind instrument in this preferred embodiment of the application, the basic fingering of the five positions is the same, and the relationship between adjacent positions is an octave relationship. The positions can be switched between each other by using different switching keys 31.

[0103] It should be noted that in the prior art, since the performers who use both hands to control the basic pitch keyboard do not have extra hands to control a large number of additional functions on the electric clarinet, many functions cannot function properly; especially due to the inability to achieve quick switching and real-time special effects, the performer has to frequently pause during the performance to perform switching operations. That is to say, in the performance method of the electric clarinet in the prior art, each pitch corresponds to a key one by one. When the performer switches the pitch, he can only frequently make switching actions in a set manner, which is not only difficult but also affects the pitch accuracy of the performer.

[0104] In the single-finger fingering system of the electric clarinet in the preferred embodiment of the present application, each pitch can have multiple different fingering methods available for selection. When the performer switches the pitch, he does not need to frequently switch the keys in a specific switching manner, reducing the frequency of using finger key switching and the amplitude of finger movement, and greatly simplifying the difficulty of the performer operating the keyboard.

[0105] It is worth mentioning that in the field of woodwind instruments to which the electric clarinet belongs, the "Boehm keyboard system" has been used for hundreds of years. No matter what woodwind instrument it is, both hands are used to control the pitch. Multiple fingerings for one pitch has been a dream in the field of woodwind music for hundreds of years, but due to the limitations of the mechanical design bottleneck of traditional woodwind instruments. The multiple fingerings for one pitch provided by the single-finger fingering system of the electric clarinet in the preferred embodiment of the present application makes the awkward jumping finger movements in the performance process become smooth and smooth finger movements, and makes the rapid connection and switching of thousands of changes between pitches in the performance become simple.

[0106] In the present application, a "fingering symbol" is regularly set for each pitch in each "position area group". Together, these numerous regular fingering symbols in the group form the "fingering symbol series" of the group. The fingerings of the five different "position area groups" are the same. In the four area groups of one, two, three, and four, their respective "fingering symbol series" are not repeated with those of other groups. Since the first group is the double bass area group and the fifth group is the ultra-high pitch area group. There is never a possibility of mutual collision and confusion between them, so the fifth group adopts the same "fingering symbol series" as the first group.

[0107] It can be understood that since most of the pitches of woodwind instruments in the prior art have only one fingering method, there have been no fingering symbols used to mark the music scores of these instruments in history. With the "multiple fingerings for one pitch" of the present invention, there is a requirement to assign a fingering symbol to each fingering of each pitch. The "electric clarinet fingering annotation system"配套 with the present application gives each fingering of each pitch of the electric clarinet its own independent symbol, facilitating the notation, reading, teaching, and communication of the electric clarinet.

[0108] Such as Figure 6The diagram shown illustrates a fingering pattern in the single-finger fingering system for the electronic wind instrument. This pattern includes the "note name," the fixed-pitch "solfège," the "octave number," and the corresponding "fingering settings," "position groups," and "finger symbols." The "position group" refers to the range covered when using the pitch keyboard 200 without any octave switching; the "octave number" refers to the octave group number on a MIDI instrument.

[0109] In this preferred embodiment of the application, each fingering module set by the pitch control module 40 has a module number, and the numbers of the 84 modules are from 01 to 84. Each pitch has a general "note name", and the symbols used to mark the fingering are called "fingering symbols". The "fingering symbol group" that marks the 22 notes of the 84 different modules of the basic pitch group has 12 fingering symbols.

[0110] As shown in the diagram, the 12 fingering symbols used in the basic pitch range are only applicable to the basic pitch range itself. Other pitch ranges each have their own unique fingering symbol sets that are distinct from those of other ranges. Because the pitch difference between the first pitch position bass range and the fifth pitch position super-high range is large, the notes used can never be the same, so these two ranges use the same fingering symbol set.

[0111] "Fingering symbols" only have meaning when associated with a specific note. When a fingering symbol is associated with a specific note, the fingering module that should be used for that note is clearly defined. At this point, the fingering symbol with specific meaning is called a "fingering mark". The same fingering symbol can mark multiple notes with different note names, generating multiple "fingering marks". Notes with the same note name do not use the same fingering symbol, so notes with the same note name cannot have the same "fingering mark".

[0112] As an example, in the case of Figures 9A to 13B The diagram shown is a comparison of the pitch input method and fingering symbols of the single-finger fingering system for an electronic wind instrument according to a preferred embodiment of this application. The first column is the fingering diagram number; the second column is the pitch frequency; the third column is the note name; the fourth column is the MIDI octave group; the fifth column is the "input method" that triggers the sound of the note—the input method here can also be called "fingering," which refers to the key that needs to be pressed on the keyboard; the sixth column is the fingering symbol for "using this fingering to trigger this note."

[0113] In this preferred embodiment of the present application, the pitch control module 40 sets the 5th key 217 to lower by a semitone and sets the 6th key 218 to raise by a semitone.

[0114] Take the "Bb" note (also called "A#" note) with a frequency of 1661.2Hz on the first page of the fourth position group as an example: The frequency of this note is 1661.2Hz, and its note name is "Ab" or "G#". This note is in the 6th group of the MIDI octave group, that is, it is the "Ab" or "G#" note in the 6th group of the octave group.

[0115] To trigger this note, press the pitch keys 21 "X", "1", and "5" on the pitch key group 20, and the switch key 31 "N" on the octave switch key group 30. The symbol used for this fingering is "J". For the same note, two other fingerings can be used: use "X", "1", and "P", and the switch key 31 "N", with the symbol used for this fingering being "P"; or use "6" and the switch key 31 "N", with the symbol used for this fingering being "R".

[0116] In other words, in the single-finger fingering system for the electronic wind instrument described in this preferred embodiment of the application, each pitch corresponds to at least one fingering (i.e., triggering method). For example, to trigger the "Bb" note (also known as the "A#" note) with a frequency of 1661.2Hz, one can choose to use the pitch keys 21 "X", "1", "5" and the switch key 31 "N"; or use "X", "1", "P" and the switch key 31 "N"; or use "6" and the switch key 31 "N". For the performer, when switching between pitches, they can choose the appropriate pitch triggering method based on the difference between the two pitches. For example, the performer can choose the fingering for the next note based on the fingering of the previous note; or choose the triggering method for the previous note based on the triggering method of the next note. This can reduce the frequency of finger movement or switching when switching pitches.

[0117] For example, the previous note is the "A" note with a trigger frequency of 3520Hz, which is triggered using "X", "1" and the toggle key "L", and is marked as "z"; the next note is the "Ab" note with a trigger frequency of 3322.4Hz, which can be triggered in three ways: one is by using the pitch keys 21 "X", "1", "5" and the toggle key "L", and is marked as "T"; the second is by using the pitch keys 21 "X", "1", "P" and the toggle key "L", and is marked as "B"; the third is by using the pitch key 21 "6" and the toggle key "L", and is marked as "A". When switching between two pitches, the performer can choose any method. For example, to switch from "z" to "T", the little finger needs to be moved to the pitch key "5" based on the previous note; to switch from "z" to "B", the middle finger needs to be moved based on the previous note; and to switch from "z" to "A", the index finger needs to be released and the little finger moved to the pitch key "6". For the first two pitch switching methods, the performer only needs to move one finger to complete the operation, while the third method requires moving two fingers. For the performer, there is no need to mechanically and frequently move the fingers; the appropriate fingering (trigger method) can be selected according to the different triggering methods (fingering) of the preceding and following notes.

[0118] It is worth mentioning that, in the single-finger fingering system for the electric wind instrument described in this preferred embodiment of the application, the single-finger fingering system for the electric wind instrument provides a multi-finger technique for one note, which can make the ever-changing connections between notes during the performance, especially the rapid connections and switches, smoother, and in particular, it can turn awkward leaps into smooth slides during the fingering process.

[0119] Since each note in this system has multiple fingering options, a complete fingering notation system is needed to distinguish them.

[0120] The technical scope of this invention is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this invention, and all such modifications and variations fall within the protection scope of this invention.

[0121] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The objectives of the present invention have been fully and effectively achieved. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and any variations or modifications may be made to the implementation of the present invention without departing from the stated principles.
