Description

Technical Field

[0001] The present invention relates to the technical field of musical instruments, and specifically refers to a chromatic harmonica with a new tuning arrangement and an in-built overblow control assistor. Background Art

[0002] The harmonica is one of the most popular musical instruments in China and even the world. Existing harmonicas are mainly divided into three types, namely the tremolo harmonica (accent harmonica), the chromatic harmonica, and the 10-hole chromatic harmonica (also called the 10-hole blues harmonica).

[0003] The current 10-hole chromatic harmonica (10-hole blues harmonica) is still a classic European design from the 19th century. The tuning arrangement of the reeds is the Richter tuning. This harmonica has two harmonica covers, a 10-hole comb, and two metal reed plates. Each reed plate has 10 reed tongues. Each sound hole has two reed tongues for blowing and sucking. One end of each reed tongue is welded or riveted to the reed tongue plate. The outer dimension of the reed tongue is just smaller than the reed tongue slot, and it can vibrate freely in the reed tongue slot. The reed tongues are the blowing reed tongue and the sucking reed tongue respectively, and two sounds with different pitches are emitted through the vibration of the blowing and sucking reed tongues. The covers, comb, and reed plates are fastened together by screws or riveting.

[0004] The following is a comparison table of the normal blowing and sucking notes, bending notes, overblowing and over sucking notes of the 10-hole Richter tuning blues chromatic harmonica.

[0005] Overblow #2 #5 #2 #4 #6 Blowing pressure bending 3b 5b 7、7b Blowing sound 1 3 5 1 3 5 1 3 5 1 Hole position 1 2 3 4 5 6 7 8 9 10 Sucking sound 2 5 7 2 4 6 7 2 4 6 Sucking pressure bending 2b 5b、4 7b, 6, 6b 2b 6b Over sucking #1 #5 #1

[0006] To facilitate the performance of minor music, pop music, and Irish music, and also take into account the performance of blues music, the blowing note of the 3rd hole of the 10-hole blues harmonica is changed to 6, which becomes the 10-hole Paddy tuning blues chromatic harmonica.

[0007] The advantages of the 10-hole Richter tuning blues chromatic harmonica are:

[0008] 1. It has strong timbre expressiveness, relatively large volume, diverse techniques. The glissando using the bending technique is its characteristic, and there are various tremolo, vibrato, and glissando performance techniques.

[0009] 2. It is very suitable for playing blues music in the second position, and is also very suitable for playing folk and rock music.

[0010] 3. It is small in size, simple in structure, durable, and easy to carry.

[0011] 4. In the mid-low pitch range, the multi-hole blowing note is the major chord, and the multi-hole sucking note is the minor chord.

[0012] The disadvantages of the 10-hole Richter tuning chromatic harmonica are:

[0013] 1. The notes 4 and 6 in the low pitch range need to be achieved through bending techniques. For harmonica learners, it is quite difficult to learn the full tone bending on the third hole. When bending a full tone to get the note 6, the pitch is unstable and the timbre is rather abrupt, which is not suitable for playing minor music with 6 as the tonic note.

[0014] 2. In actual musical performances, special playing techniques are often required to obtain additional notes to achieve the desired effect. Besides the bends obtained through bending techniques, many semitones need to be achieved through overblowing and overdrawing techniques.

[0015] (1) Inhale bend: On holes 1 to 6, when inhaling, by changing the shape of the mouth and tongue to change the angle of the air flow, through the interaction of the inhale reed and the blow reed in this sound hole, the pitch of the inhale sound is lowered (the note with the lowered pitch is between the inhale sound and the blow sound within this sound hole).

[0016] (2) Exhale bend: On holes 7 to 10, when exhaling, by changing the shape of the mouth and tongue to change the angle of the air flow, through the interaction of the inhale reed and the blow reed in this sound hole, the pitch of the exhale sound is lowered (the note with the lowered pitch is between the exhale sound and the inhale sound within this sound hole).

[0017] (3) Overblow: On holes 1 to 6, when exhaling, by changing the shape of the mouth, tongue and throat, the air flow blown out of the mouth closes the blow reed (the reed vibrates slightly with a very small amplitude in the reed slot), forcing the air flow to point to the draw reed, and making the draw reed sound, thus obtaining a note with a pitch half a tone higher than the draw note.

[0018] (4) Overdraw: On holes 7 to 10, when inhaling, by changing the shape of the mouth, tongue and throat and appropriately controlling the intensity and direction of the air flow, closing the draw reed, forcing the air flow to point to the blow reed, making the blow reed vibrate and produce a note with a pitch half a tone higher than the normal blow note of this reed.

[0019] 3. The techniques of overblowing and overdrawing are very difficult to master, often accompanied by whistling phenomena, and it is also not easy to control the timbre and intonation.

[0020] 4. Because overblowing and overdrawing require long-term training and certain talent to be possibly mastered, the vast majority of learners and performers cannot master the techniques of overblowing and overdrawing.

[0021] 5. The scale arrangements in the three pitch ranges of low pitch, middle pitch and high pitch are all different, which is not convenient for learning.

[0022] In the prior art, for example, a diatonic harmonica and its auxiliary controllable shell disclosed in the patent application No. CN201811178918.X. It is very difficult to find the corresponding air holes to be blocked during playing with this patented technology. It is very uncomfortable and inconvenient to block the holes with fingers, and it is very difficult to ensure airtightness.

[0023] For another example, a Blues 10-hole diatonic harmonica with a super blow control auxiliary device designed and manufactured by the Japanese Suzuki Harmonica Company. It is very difficult to ensure airtightness during operation, with serious air leakage and difficult control of overtones, resulting in product failure.

[0024] For another example, the US patent Harmonica and method of playing same with the patent number 5739446. It is very difficult to meet the requirements in terms of airtightness, resulting in poor playing effects.

[0025] For another example, a harmonica overblow enhancement component and an overblow harmonica disclosed in the patent application No. CN201820598804.X. The overblow air guide holes of this design are two upper and lower rows of holes at the rear of the harmonica. When blocking the air guide holes with the straightened right hand fingers, it is necessary to determine which note it is, and decide whether to block the upper or lower air guide holes. Moreover, the action of blocking the air guide holes needs to be frequently changed between the upper and lower rows of air guide holes, making it not easy to master and control the position of the fingers, and easily leading to mistakes in playing overblow notes. To overcome this shortcoming, a gas blocking baffle link is designed in this creation. When using the gas blocking link for operation, since the opening and closing rotation of the link and the connection end of the harmonica are connected by two screw shafts, it is not easy to ensure that the angle of the baffle blocking the outer edge surface of the air guide hole is straight, resulting in easy air leakage and poor airtightness, and easily leading to failure in playing overblow notes. In addition, the additional baffle link has no fixed position limit, and the long baffle link hanging down and swaying is very easy to be damaged and needs to be carefully stored, making the harmonica lose the advantage of portability.

[0026] Therefore, a new type of diatonic harmonica with an internal overblow control auxiliary device and a new tuning arrangement is proposed to solve the existing deficiencies. Summary of the Invention

[0027] The technical problem to be solved by the present invention is to overcome the above-mentioned technical defects and provide a new type of diatonic harmonica with an internal overblow control auxiliary device and a new tuning arrangement.

[0028] To solve the above technical problems, the technical solution provided by the present invention is a new type of diatonic harmonica with an internal overblow control auxiliary device and a new tuning arrangement: including a harmonica body;

[0029] The harmonica body includes a blowing sound cover plate, an overblow isolation airway module, a blowing sound reed plate, a fretboard, a sucking sound reed plate, and a sucking sound cover plate. The fretboard is evenly provided with a number of linearly increasing sound holes along the length direction. The blowing sound reed plate and the sucking sound reed plate are respectively arranged on the upper and lower sides of the fretboard. The blowing sound reed plate and the sucking sound reed plate are provided with sound reed grooves corresponding to the sound holes. The blowing sound reed plate is provided with an overblow isolation airway module. The overblow isolation airway module is provided with partition cavities arranged linearly and corresponding to the sound reed grooves. The partition cavities in the overblow isolation airway module and the blowing sound reed plate form an overblow isolation airway. The blowing sound cover plate is arranged outside the blowing sound reed plate and the overblow isolation airway module. The sucking sound cover plate is arranged outside the sucking sound reed plate.

[0030] It further includes a blowing sound reed piece and a sucking sound reed piece. The blowing sound reed piece is arranged on the blowing sound reed plate and is adapted to the sound reed groove. The sucking sound reed piece is arranged on the sucking sound reed plate and is adapted to the sound reed groove.

[0031] As an improvement, the pitch of the corresponding sound holes is controlled by the thickness and length of the blowing sound reed piece and the sucking sound reed piece.

[0032] As an improvement, the overblow isolation airway module includes an isolation airway upper plate, an isolation airway outer plate, an isolation airway bottom plate, and an isolation airway baffle. The overblow isolation airway module is fixedly arranged on the upper side of the blowing sound reed plate.

[0033] As an improvement, the overblow isolation airway module is closely attached to the blowing sound reed plate.

[0034] As an improvement, the outlet of the partition cavity in the overblow isolation airway module is flush with the rear end of the fretboard.

[0035] The advantages of the present invention compared with the prior art are as follows:

[0036] 1. All whole tones and semitones within 2.5 octaves can be played simply and conveniently. At the same time, without the need for bending, the bass 4 and bass 6 can be obtained by natural blowing and sucking of the reeds.

[0037] 2. Special playing techniques such as bending and overblowing are not required. The natural blowing and sucking reeds on the harmonica obtain the natural scales of two keys, C and F (1, 2, 3, 4, 5, 6, 7, taking a C-tuned harmonica as an example), which are simple and easy to use.

[0038] The bending technique in the high pitch range eliminates the blowing sound bending technique and combines the sucking sound bending technique. At the same time, the three-octave scale arrangements in the low, middle, and high pitch ranges are the same, which is convenient for learning, memorizing, and mastering.

[0039] 3. By using the overblow isolation airway module, techniques such as tongue trill, jaw trill, throat trill, hand trill, and upward glissando can be used on overblown notes, with strong control and rich expressiveness. Moreover, overblown notes are easy to quickly learn and master, and the pitch and timbre of overtones can be precisely controlled;

[0040] 4. For overblowing, place the side of the middle finger or index finger of the right hand flat against the air outlet of the overblow control auxiliary isolation airway to block the air outlet of the overblow isolation airway module, and blow the inhalation reed in the sound hole to produce overblown notes. Overblown notes are easier to obtain, with a pure timbre and simple and practical operation.

[0041] 5. With the overblown notes using the overblow isolation airway module, through the cooperation of finger and oral control, the pitch and timbre of overtones can be precisely and quickly controlled. Ornamental techniques such as lip trill, throat trill, hand trill, upward glissando, and downward glissando can be played on overblown notes, expanding the musical expressiveness of the harmonica;

[0042] 6. The upward glissando of overblowing can raise the pitch by another semitone through the shape of the mouth cavity and airflow control. In this way, the upward glissando of each blowing note can be obtained through the overtones of the adjacent sound holes on the left. Since each drawing note can achieve the draw bend upward glissando through the draw bend technique, and after the implementation of this solution, the overblown upward glissando of each blowing note can be achieved, thus greatly expanding the musical expressiveness of the harmonica.

[0043] 7. By using the side of the middle finger or index finger placed flat to block the air outlet of the overblow isolation airway, it is convenient to play pure overblown notes, and the tuning of each reed is redesigned, eliminating blowing draw bend and overdraw. Thus, all the missing semitone notes on the diatonic harmonica are complemented through draw bend and overblowing, making the diatonic harmonica an instrument that is easy to learn, powerful in function, rich in timbre, small in size, durable, and convenient to operate, and can play pop music, classical music, jazz, blues music, and music of various ethnic groups in the world.

[0044] 8. It has a relatively large volume, strong timbre control, powerful timbre expressiveness, simple structure, no moving parts, is not easily damaged, is convenient to learn, has a powerful performance function, can play major and minor key music in all keys, and can also play various styles of music including pop music, classical music, jazz, folk music, blues, rock, and music of various ethnic groups in the world.

[0058] Embodiment 1

[0059] A diatonic harmonica with a new tuning arrangement incorporating a super blow control assistor, comprising a harmonica body;

[0060] The harmonica body includes a blowing sound cover plate 1, a super blow isolation airway module 2, a blowing sound reed plate 3, a harmonica frame 4, a sound-absorbing reed plate 5, and a sound-absorbing cover plate 6. Along the length direction of the harmonica frame 4, a number of linearly increasing note holes 7 are evenly provided. Specifically, the number of the note holes 7 can be set according to actual requirements. In this embodiment, the number of the note holes 7 is 10.

[0061] A blowing sound reed plate 3 and a sound-absorbing reed plate 5 are respectively provided on the upper and lower sides of the harmonica frame 4. Sound reed grooves 8 corresponding to the note holes 7 are provided on the blowing sound reed plate 3 and the sound-absorbing reed plate 5. A super blow isolation airway module 2 is provided on the blowing sound reed plate 3. Linear-arranged partition chambers 9 corresponding to the sound reed grooves 8 are provided in the super blow isolation airway module 2. The partition chambers 9 in the super blow isolation airway module 2 and the blowing sound reed plate 3 form a super blow isolation airway;

[0062] Specifically, the super blow isolation airway module 2 includes an isolation airway upper plate 12, an isolation airway outer side plate 13, an isolation airway bottom plate 14, and an isolation airway baffle 15. The super blow isolation airway module 2 is fixedly arranged on the upper side of the blowing sound reed plate 3.

[0063] In specific implementation, by arranging a super blowing isolation airway module 2 between the blowing reed plate 3 and the blowing cover plate 1, the linearly arranged super blowing isolation airways formed between the super blowing isolation airway module 2 and the blowing reed plate 3 enable each sound hole 7 to have an independent super blowing isolation airway, which is isolated from adjacent super blowing isolation airways. At the same time, since the air outlet holes of the super blowing isolation airways are at the rear of the harmonica, that is, when performing super blowing, straighten the middle finger or index finger of the right hand and lean it on the air outlet holes of the super blowing isolation airways at the rear of the harmonica, block the air outlet holes, and blow air towards the sound holes of the harmonica to blow the blowing reed piece 11 of the sound hole to sound, and the super blowing sound of the air hole can be emitted. The operation is simple, convenient for performance, and consistent with the traditional harmonica holding action.

[0064] To ensure airtightness, the super blowing isolation airway module 2 is closely attached to the blowing reed plate 3, and at the same time, the outlet of the partition cavity 9 in the super blowing isolation airway module 2 is flush with the rear end of the harmonica grid 4.

[0065] A blowing cover plate 1 is arranged outside the blowing reed plate 3 and the super blowing isolation airway module 2, and a sound absorbing cover plate 6 is arranged outside the sound absorbing reed plate 5;

[0066] It further includes a blowing reed piece 11 and a sound absorbing reed piece 10. The blowing reed piece 11 is arranged on the blowing reed plate 3 and is adapted to the sound reed groove 8, and the sound absorbing reed piece 10 is arranged on the sound absorbing reed plate 5 and is adapted to the sound reed groove 8.

[0067] Furthermore, the pitch of the corresponding sound hole 7 is controlled by the thickness and length of the blowing reed piece 11 and the sound absorbing reed piece 10.

[0068] In specific implementation, the sound sequence arrangement of the blowing reed piece 11 of the blowing reed plate 3, the sound absorbing reed piece 10 of the sound absorbing reed plate 5, as well as the corresponding super blowing sound and bending sound:

[0069] Overblowing sound #2 #4 #2 #4 #2 #4 Blowing sound 1 3 5 7b 1 3 5 7b 1 3 Hole position 1 2 3 4 5 6 7 8 9 10 Sucking sound 2 4 6 7 2 4 6 7 2 4 Sucking pressure bending 2b 6b 2b 3b 6b 2b

[0070] Note: For a new-style tuning arrangement full-scale harmonica with a built-in super blowing control assistor, the sounds of each sound hole (for a 10-hole full-scale harmonica, from left to right, the sound holes are successively called the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, and 10th holes).

[0071] Embodiment 2

[0072] A new-style tuning arrangement full-scale harmonica with a built-in super blowing control assistor, including a harmonica body;

[0073] The harmonica body includes a blowing cover plate 1, an over-blowing isolation airway module 2, a blowing reed plate 3, a fret 4, a sound-absorbing reed plate 5, and a sound-absorbing cover plate 6. The fret 4 is evenly provided with a plurality of linearly increasing sound holes 7 along the length direction. Specifically, the number of the sound holes 7 can be set according to actual needs. In the embodiment itself, the number of the sound holes 7 is 10 holes.

[0074] The upper and lower sides of the fret 4 are respectively provided with a blowing reed plate 3 and a sound absorbing reed plate 5, and the blowing reed plate 3 and the sound absorbing reed plate 5 are provided with a reed groove 8 corresponding to the sound hole 7, and the blowing reed plate 3 is provided with an over-blowing isolation airway module 2, and the over-blowing isolation airway module 2 is provided with a partition cavity 9 which is linearly arranged and arranged corresponding to the reed groove 8, and the partition cavity 9 in the over-blowing isolation airway module 2 and the blowing reed plate 3 constitute an over-blowing isolation airway;

[0075] Specifically, the super-blowing isolation airway module 2 includes an isolation airway upper plate 12 , an isolation airway outer plate 13 , an isolation airway bottom plate 14 and an isolation airway baffle 15 , and the super-blowing isolation airway module 2 is fixedly arranged on the upper side of the blowing reed plate 3 .

[0076] In the specific implementation, by setting the over-blowing isolation airway module 2 between the blowing reed plate 3 and the blowing cover plate 1, the linearly arranged over-blowing isolation airways formed between the over-blowing isolation airway module 2 and the blowing reed plate 3 make each sound hole 7 have an independent over-blowing isolation airway, which is isolated from the adjacent over-blowing isolation airways. At the same time, since the air outlet of the over-blowing isolation airway is at the rear of the harmonica, that is, when over-blowing, the middle finger or index finger of the right hand is straightened and leaned on the air outlet of the over-blowing isolation airway at the rear of the harmonica to block the air outlet, blow air into the sound hole of the harmonica, blow the blowing reed 11 of the sound hole to make a sound, and then the over-blowing sound of the air hole can be emitted. The operation is simple, convenient to play, and consistent with the traditional piano holding action.

[0077] To ensure air tightness, the super-blowing isolation airway module 2 is tightly fitted to the reed blowing plate 3 , and at the same time, the exit of the compartment 9 in the super-blowing isolation airway module 2 is flush with the rear end of the fret 4 .

[0078] A sound blowing cover plate 1 is arranged outside the sound blowing reed plate 3 and the super-blowing isolation airway module 2, and a sound absorbing cover plate 6 is arranged outside the sound absorbing reed plate 5;

[0079] It also includes a blowing reed 11 and a sound absorbing reed 10 . The blowing reed 11 is arranged on the blowing reed plate 3 and is matched with the reed groove 8 . The sound absorbing reed 10 is arranged on the sound absorbing reed plate 5 and is matched with the reed groove 8 .

[0080] Furthermore, the pitch of the sound produced by the corresponding sound hole 7 can be controlled by adjusting the thickness and length of the sound blowing reed 11 and the sound absorbing reed 10 .

[0081] In specific implementation, the sequence arrangement of the blowing reed pieces 11 of the blowing reed plate 3 and the sucking reed pieces 10 of the sucking reed plate 5, as well as the corresponding overblowing sounds and bending sounds:

[0082] Overblowing sound #2 #5 #2 #4 #2 #4 7b Blowing sound 1 3 6 1 3 5 7b 1 3 5 Hole position 1 2 3 4 5 6 7 8 9 10 Sucking sound 2 5 7 2 4 6 7 2 4 6 Sucking pressure bending 2b 5b、4 7b 2b 6b 2b 6b

[0083] Note: Based on the 10-hole Paddy-tuned diatonic harmonica, the tuning arrangement of the tone reeds of each sound hole is as follows: (For a 10-hole diatonic harmonica, from left to right, the sound holes are successively called the 1st, 2nd, 3rd, 4th, 5th, 6th, 7th, 8th, 9th, and 10th holes).

[0084] During use, if you want to play the effect of the main chord with multi-hole blowing in the low pitch range, when blowing the multi-hole blowing sounds and chord sounds in the middle and low pitch ranges, you can bend the middle finger of the right hand holding the harmonica, so that the second joint of the bent middle finger just blocks the third hole of the overblowing isolation air outlet at the rear of the harmonica, blocks the third hole that emits the 6 sound, and emits the main chord sounds of 1, 3, and 5.

[0085] The feature of this second embodiment is that it can play blues-style music using the second position of the harmonica.

[0086] Using the side of the bent middle finger of the left hand holding the harmonica, the air outlet of the second hole can be blocked. When playing the harmony in the low pitch range, the chords of 1, 3, 1, 3, 5 can be blown. When the air outlet of the second hole is released, the chords of 1, 3, 6, 1, 3 can be blown.

[0087] It not only retains the traditional chord playing methods of the main chord and the subdominant chord in the low pitch range during the performance of the second position of the blues harmonica, but also can play the major main chord and the minor main chord of the first position. At the same time, double-tone techniques can be performed, 13, 25, 57, 61, 72, 13, 24, 35, 46, 5b7, 1351 (block the air outlet of the 7th hole with the side of the left middle finger), which greatly expands the expressiveness of the harmonica.

[0090] The harmonica body includes a blowing cover plate 1, an overblowing isolation airway module 2, a blowing reed plate 3, a harmonica grille 4, a sucking reed plate 5, and a sucking cover plate 6. Along the length direction of the harmonica grille 4, a number of linearly increasing sound holes 7 are evenly provided. Specifically, the number of the sound holes 7 can be set according to actual needs. In this embodiment, the number of the sound holes 7 is 10 holes.

[0091] On the upper and lower sides of the fret 4, a blowing reed plate 3 and a sound-absorbing reed plate 5 are respectively provided. Sound reed grooves 8 corresponding to the sound holes 7 are provided on the blowing reed plate 3 and the sound-absorbing reed plate 5. A super blowing isolation airway module 2 is provided on the blowing reed plate 3. In the super blowing isolation airway module 2, isolation cavities 9 arranged linearly and corresponding to the sound reed grooves 8 are provided. The isolation cavities 9 in the super blowing isolation airway module 2 and the blowing reed plate 3 form a super blowing isolation airway;

[0092] Specifically, the super blowing isolation airway module 2 includes an isolation airway upper plate 12, an isolation airway outer side plate 13, an isolation airway bottom plate 14, and an isolation airway baffle 15. The super blowing isolation airway module 2 is fixedly arranged on the upper side of the blowing reed plate 3.

[0093] In specific implementation, by arranging the super blowing isolation airway module 2 between the blowing reed plate 3 and the blowing cover plate 1, the linearly arranged super blowing isolation airway formed between the super blowing isolation airway module 2 and the blowing reed plate 3 enables each sound hole 7 to have an independent super blowing isolation airway, which is isolated from the adjacent super blowing isolation airways. At the same time, since the air outlet holes of the super blowing isolation airway are at the rear of the harmonica, that is, when doing super blowing, straighten the middle finger or index finger of the right hand and lean it on the air outlet holes of the super blowing isolation airway at the rear of the harmonica, block the air outlet holes, and blow air towards the sound holes of the harmonica to blow the blowing reed piece 11 of the sound hole to sound, and the super blowing sound of this air hole can be emitted. The operation is simple, convenient for playing, and consistent with the traditional harmonica-holding action.

[0094] To ensure airtightness, the super blowing isolation airway module 2 and the blowing reed plate 3 are closely attached. At the same time, the outlet of the isolation cavity 9 in the super blowing isolation airway module 2 is flush with the rear end of the fret 4.

[0095] A blowing cover plate 1 is arranged outside the blowing reed plate 3 and the super blowing isolation airway module 2, and a sound-absorbing cover plate 6 is arranged outside the sound-absorbing reed plate 5;

[0096] It further includes a blowing reed piece 11 and a sound-absorbing reed piece 10. The blowing reed piece 11 is arranged on the blowing reed plate 3 and is adapted to the sound reed groove 8, and the sound-absorbing reed piece 10 is arranged on the sound-absorbing reed plate 5 and is adapted to the sound reed groove 8.

[0097] Furthermore, by controlling the thickness and length of the blowing reed piece 11 and the sound-absorbing reed piece 10, the pitch of the corresponding sound hole 7 is controlled.

[0098] In specific implementation, the sound sequence arrangement of the blowing reed piece 11 of the blowing reed plate 3, the sound-absorbing reed piece 10 of the sound-absorbing reed plate 5, and the corresponding super blowing sound and bending sound:

[0099] Overblowing sound #2 #5 #2 #4 #2 #4 7b Blowing sound 1 3 5 1 3 5 7b 1 3 5 Hole position 1 2 3 4 5 6 7 8 9 10 Sucking sound 2 5 7 2 4 6 7 2 4 6 Sucking pressure bending 2b 5b、4 6b, 6, 7b 2b 6b 2b 6b

[0100] This embodiment upgrades the functions of a 10-hole classical blues Richter-tuned diatonic harmonica. On the basis of retaining the basic functions and playing methods of a 10-hole classical blues Richter-tuned diatonic harmonica, it is convenient to play the overblown semitones and can precisely control the timbre decoration of the overblown notes, improving the playing performance ability of the blues harmonica.

[0101] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the gist of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
