Description

[Technical Field]

[0001] The present invention relates to a rhythm learning tool and a rhythm learning method for learning accurate rhythm while being conscious of beats. [Background Art]

[0002] In music learning, it is important to accurately mark the rhythm written in a score at a constant tempo (beat) written in the score. Generally, when practicing marking rhythm while being conscious of beats, a metronome that produces sounds at a constant tempo is used, and practice is performed to mark rhythm in accordance with the tempo of the metronome. However, when trying to grasp rhythm while matching the sound of the metronome, a learner tends to focus solely on matching the metronome, and when actually performing without a metronome, the learner often cannot maintain tempo and mark rhythm on their own.

[0003] On the other hand, without using a metronome, a music learning score has also been developed that displays graphics on the score to make the learner conscious of the accent of beats, allowing the learner to visually recognize the graphics and mark rhythm while being conscious of the beats and beat accents (see, for example, Patent Document 1). In the music learning score of Patent Document 1, a plurality of rectangular framed notes with different horizontal lengths corresponding to the duration of notes are arranged connected in the horizontal direction, and graphics for making the learner conscious of beat accents are displayed on the upper part of the rectangular framed notes. When using such a music learning score, a learner can practice marking the rhythm of notes while grasping the tempo on their own, while looking at the graphics displayed on the upper part of the notes.

[0015] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings. The rhythm learning tool according to the present invention is a teaching material for learning various rhythms that are basic to time signatures so that accurate rhythms can be produced while being conscious of beats.

[0016] [Embodiment 1] The rhythm learning tool 1a according to Embodiment 1 will be described with reference to Figures 1 to 4. Figure 1 is a perspective view showing the rhythm learning tool 1a according to Embodiment 1. Figure 2 is a front view of the rhythm learning tool 1a of Embodiment 1. Figure 3 is a cross-sectional view of the board 11 of the rhythm learning tool 1a of Embodiment 1, taken along line AA. Figure 4 is a front view showing an example of a card 21 of the rhythm learning tool 1a of Embodiment 1. Hereinafter, as shown in Figures 1 and 2, the up-down and left-right directions will be defined from the viewpoint of a learner facing the rhythm learning tool 1a. The direction perpendicular to the up-down and left-right directions will be defined as the front-back direction.

[0017] The rhythm learning device 1a comprises a time signature indicator 10, a note / rest indicator 20, and a sound generation mechanism 30.

[0018] The time signature indicator 10 displays the time signature 41. As shown in Figures 1 to 3, in Embodiment 1, the time signature indicator 10 is a board 11 having a hollow section 12 inside. On the surface 111 of the board 11, several main time signatures 41 are displayed in a vertical direction. In addition, on the surface 111 of the board 11, a frame 42 that divides one beat indicated by the time signature 41 is displayed horizontally to the time signature 41 for at least one measure, and a beat indicator 43 indicating the beat is displayed inside the frame 42.

[0019] The time signature 41 is a symbol that indicates the reference note representing the length of one beat and the number of reference notes contained in one measure. There are various time signatures 41, but in Embodiment 1, in order to learn the basics of rhythm, the reference note that displays the length of one beat is a quarter note or an eighth note, and among these, the time signatures 41 for the particularly basic 2 / 4 time, 3 / 4 time, 4 / 4 time, 3 / 8 time, and 6 / 8 time are displayed.

[0020] The frame 42 is formed in a rectangular shape. The frame 42 has a dividing line 421 that divides the inside of the frame 42 vertically, and a vertical line 422 that indicates the division of one measure. Specifically, for example, in 2 / 4 time, one frame 42 corresponds to one quarter note, and one measure corresponds to two quarter notes, so the vertical line 422 is provided to the right of the second frame 42, to the right of the fourth frame 42, and so on. Similarly, for example, in 3 / 8 time, one frame 42 corresponds to one eighth note, and one measure corresponds to three eighth notes, so the vertical line 422 is provided to the right of the third frame 42, to the right of the sixth frame 42, and so on. The dividing line 421 is preferably provided as a dashed line to make it easier to distinguish it from the frame 42 visually. The vertical line 422 is provided as a solid line that is thicker than the frame 42.

[0021] The beat indicator 43 is displayed above the dividing line 421 inside the frame 42. Preferably, the beat indicator 43 is displayed at the upper left end inside the frame 42. In Embodiment 1, the beat indicator 43 is shown as a black circle. The beat indicator 43 is not limited to a black circle; it may be any other shape, or a design such as a metronome or castanets that makes the beat more noticeable. Preferably, the beat indicator 43 is displayed with varying sizes to match the dynamics of the beat indicated by the time signature 41. That is, for example, in 4 / 4 time, generally, the first beat is played strongly, the second weakly, the third mediumly, and the fourth weakly. To make this visible, the beat indicator 43 can be shown as a large black circle for the first beat, a small black circle for the second beat, a medium-sized black circle for the third beat, and a small black circle for the fourth beat. This allows students to learn about dynamics, which are essential for learning rhythm.

[0022] In Embodiment 1, the time signature 41, the frame 42, and the beat indicator 43 are displayed by printing or the like on the surface 111 of the board 11.

[0023] The note / rest indicator 20 is used in combination with the time signature indicator 10 to display either a note 51 or a rest 52. The note / rest indicator 20 is roughly rectangular in shape and has a horizontal length that is a natural number multiple of the note value of one beat indicated by the time signature 41. The note / rest indicator 20 also displays a note 51 or a rest 52 inside that corresponds to the note value indicated by the horizontal length of the note / rest indicator 20.

[0024] In Embodiment 1, the note / rest indicator 20 is a card 21 that is roughly rectangular in shape and sized to fit inside the frame 41 displayed on the board 11. When the card 21 is combined with the board 11 and placed inside the frame 41, it is sized so that the frame 41 is visible, that is, it is slightly smaller than the frame 41. There are multiple types of cards 21, and each card 21 displays various notes 51 or rests 52 necessary to form the basic rhythm in the time signature indicated by the time signature 41 displayed on the time signature indicator 10. When the note 51 or rest 52 displayed on the card 21 corresponds to the note value of one beat of the time signature 41, the card 21 is sized to fit inside one frame 42. When the note 51 or rest 52 displayed on the card 21 corresponds to the note value of two or more beats of the time signature 41, the card 21 is sized to fit inside a series of horizontally connected frames 42 corresponding to the number of beats indicated by the note value. In other words, card 21 is sized to fit inside two connected frames 42 if the displayed note 51 or rest 52 indicates a note value of two beats in the time signature 41, and sized to fit inside three connected frames 42 if the displayed note 51 or rest 52 indicates a note value of three beats in the time signature 41.

[0025] If the card 21 has two or more beats, it has dividing lines 22 that separate each beat. That is, the card 21 is divided into sections equal to the number of beats by the dividing lines 22. It is preferable that the dividing lines 22 are represented by lines different from the frame 42 displayed on the board 11, such as dashed lines as shown in Figures 1 and 2, lines thinner than the lines representing the frame 42, or lines of a different color from the lines representing the frame 42.

[0026] The note 51 or rest 52 displayed on card 21 is a note 51 or rest 52 with a note value corresponding to the length of the beat indicated by card 21. That is, in a time signature where one beat is a quarter note, a card 21 corresponding to the horizontal length of one frame 42 (a one-beat card 21) will display, for example, one quarter note or a quarter rest. To display an eighth note, which has half the note value of a quarter note, two eighth notes will be displayed. The same applies when displaying triplets of eighth notes, sixteenth notes, dotted eighth notes, etc. Similarly, a card 21 corresponding to the horizontal length of two frames 42 (a two-beat card 21) will display, for example, one half note when displaying a half note, which has twice the note value of a quarter note. When displaying a dotted quarter note, since a dotted quarter note and an eighth note together correspond to a note value of two beats, a dotted quarter note and an eighth note will be displayed. The same applies to cards 21 that correspond to the horizontal length of three or more frame bodies 42 (cards 21 with three or more beats).

[0027] For cards 21 with two or more beats, the note 51 or rest 52 is written within the section separated by the dividing line 22, in the section corresponding to the beat number on which the note 51 or rest 52 is inscribed. That is, the note 51 or rest 52 inscribed on the first beat is written in the first section from the left, the note 51 or rest 52 inscribed on the second beat is written in the second section from the left, and the note 51 or rest 52 inscribed on the third beat is written in the third section from the left.

[0028] The same applies to time signatures where an eighth note constitutes one beat. A card 21 corresponding to the horizontal length of one frame 42 (a one-beat card 21) will display, for example, one eighth note, one eighth rest, or two sixteenth notes. A card 21 corresponding to the horizontal length of two frame 42 (a two-beat card 21) will display, for example, one quarter note, or a combination of a dotted eighth note and a sixteenth note.

[0029] As shown in Figure 4, the card 21 used in a time signature where one beat is a quarter note displays a note 51 or rest 52 on the front 211 of the card 21, and displays a language 53 on the back 212 of the card 21 that corresponds to the rhythm of the note 51 or rest 52 on the front 211. In addition, some cards 21 have an image 54 on the back 212 that represents the language 53. When there is one beat, the language 53 is set according to the number of note heads of the note 51 and corresponds to the number of note heads and the note value of the note 51. When there are two beats, the language 53 is set according to the note value of the note 51 and corresponds to the note value of the note 51. When there are three or more beats, the language 53 is set according to the number of beats and corresponds to the number of beats. Here, the number of characters in the language 53 is counted as follows: long vowels "ー" are counted as one character, and diphthongs "ゃ, ゅ, ょ" and geminate consonants "っ" are counted as one character together with the preceding character. In other words, "juice" consists of three letters: "ju," one "-," and one "su."

[0030] Specifically, regarding the rhythm of one beat, for a rhythm of one quarter note, language 53 is a two-letter language formed by adding "n" to the end of a one-letter language corresponding to the number of note heads, corresponding to the note value of note 51. For example, language 53 would be "chan," "tan," "un," etc. For a rhythm of two eighth notes, and a rhythm combining one dotted eighth note and one sixteenth note, language 53 is a two-letter language corresponding to the number of note heads. For example, language 53 would be "neko," "inu," etc. For a rhythm of eighth note triplets, and a rhythm combining one eighth note and two sixteenth notes, language 53 is a three-letter language corresponding to the number of note heads. For example, language 51 would be "tanuki," "kitsune," etc. For a rhythm of four sixteenth notes, language 53 is a four-letter language corresponding to the number of note heads. For example, language 53 includes words like "zebra," "seal," "polar bear," and "Donald." Since eighth notes, dotted eighth notes, and sixteenth notes have shorter note values ​​than the basic quarter note, language 53 for rhythms other than those using a single quarter note corresponds to the note value of note 51, and has no suffix, resulting in a language with a number of letters corresponding to the number of note heads.

[0031] Regarding two-beat rhythms, in a rhythm with one half note, language 53 has a note value that extends over two beats, so the word ending corresponding to the note value of note 51 is a two-letter word with a long vowel. For example, "zo" and "ka". In a rhythm combining one dotted quarter note and one eighth note in sequence, language 53 has a note value of the first note 51 that is long and a note value of the second note 51 that is short, so the word ending corresponding to the note value of note 51 is a three-letter word with a long vowel. For example, "juice" and "boat". Conversely, in a rhythm combining one eighth note and one dotted quarter note in sequence, language 53 has a note value of the first note 51 that is short and a note value of the second note 51 that is long, so the word ending corresponding to the note value of note 51 is a three-letter word with a long vowel. For example, "curry" and "stew". In a rhythm that combines eighth notes, quarter notes, and eighth notes in sequence, language 53 is a four-letter language where the third letter, corresponding to the note value of note 51, is a long vowel because the note values ​​of the first and third notes 51 are short, while the note value of the second note 51 is long. Examples include "steak," "skirt," and "airplane."

[0032] In a time signature where one beat is a quarter note, a single quarter note rhythm is the most basic rhythm, a rhythm where the beat is consciously considered, and is often associated with language 53, which is used when taking beats, such as "chan," "tan," and "un." Since there is no suitable image 54 for language 53, only language 53 is displayed on the back of card 212. For other rhythms, language 53 is often associated with language 53 for which an image 54 exists, so both language 53 and image 54 are displayed on the back of card 212.

[0033] The sound-producing mechanism 30 is a mechanism that produces sound when force is applied to the beat indicator unit 43. In Embodiment 1, as shown in Figure 3, the sound-producing mechanism 30 is made up of the hollow portion 12 inside the board 11. That is, because the inside of the board 11 is a hollow portion 12, sound resonates in the hollow portion 12, and when the surface 111 of the board 11 is struck, a sound is produced.

[0034] Card 21 is made of resin or paper and has a magnet inside. Board 11 is made of metal, wood, or resin. If board 11 is made of a material other than a ferromagnetic material, a ferromagnetic metal is placed inside the plate material that forms the surface 111 of board 11. Board 11 and card 21 can be attached to and detached from the surface 111 of board 11, which has a ferromagnetic metal, by the magnet placed in card 21.

[0035] Next, the method of using the rhythm learning tool 1a will be explained with reference to Figure 9. Figure 9 is a front view showing an example of a rhythm-language chart 100 used with the rhythm learning tools 1a and 1b of the present invention. The rhythm learning tool 1a is used together with the rhythm-language chart 100, which lists musical notes 51 or rests 52 that represent multiple basic rhythms, and languages ​​53 that verbalize the rhythms of those musical notes 51 or rests 52.

[0036] First, a learner of rhythm, or an instructor teaching rhythm to a learner, creates a musical score of the desired rhythm by arranging note and rest indicators 20 next to the time signature 41 to represent various rhythms corresponding to the time signature 41. The rhythm to be learned could be, for example, the rhythm of a new piece of music to be played. Specifically, a card 21 showing the notes 51 or rests 52 that make up the desired rhythm is selected next to the time signature 41 of the desired rhythm, and the card 21 is pasted inside the frame 42 of the board 11 to create a musical score of the desired rhythm. For example, a rhythm like the one shown in Figure 2 is created.

[0037] The learner finds the language 53 corresponding to the musical note 51 or rest 52 of the rhythm shown by the rhythm learning tool 1a from the rhythm language list 100 shown in Figure 9, and applies the language 53 to the rhythm shown by the rhythm learning tool 1a. Then, while applying force to the beat indicator 43 at a constant tempo to produce a sound, the learner pronounces the language 53 corresponding to the note value of the musical note 51 or rest 52. In Embodiment 1, since a sound is produced by tapping on the beat indicator 43, the learner pronounces the language 53 corresponding to the note value of the musical note 51 or rest 52 while tapping the beat indicator 43. This allows the learner to learn rhythm while being aware of the beat.

[0038] [Modified example of Embodiment 1] In the above embodiment 1, the beat display unit 43 is displayed by printing or the like on the surface 111 of the board 11, and the sound generation mechanism 30 is described as being composed of the hollow part 12 inside the board 11. However, the beat display unit 43 and the sound generation mechanism 30 may be in other configurations as shown in Figure 5. Figure 5 is a cross-sectional view of the board 11 of the rhythm learning tool 1a, a modified example of embodiment 1, along line AA.

[0039] In a modified embodiment of Embodiment 1, the beat indicator 43 is a button 431 that protrudes from the surface 111 of the board 11 and can be pressed toward the interior of the board 11. When the rhythm learning tool 1a is viewed from the front, the button 431 is circular as shown in Figure 2. In a modified embodiment of Embodiment 1, the board 11 has a rod-shaped member 112 that is slidably attached to the plate material forming the surface 111 of the board 11. The rod-shaped member 112 extends from the outside (outside) of the surface 111 of the board 11 to the hollow portion 12 (inside). The rod-shaped member 112 is configured to move inward when pressed from the outside of the board 11 by an elastic member (not shown), and to move outward when the force pressing the rod-shaped member 112 is released. The button 431 is attached to the outer end of the rod-shaped member 112.

[0040] In a modified embodiment of Embodiment 1, the sound-producing mechanism 30 is composed of a drive element 31 that is linked to a button 431, and a contact plate 32 that is positioned inside the board 11 so that the drive element 31 can contact it. The drive element 31 is rotatably mounted on a shaft member 33 that is attached to a plate material that makes up the left and right walls of the board 11. The drive element 31 is composed of an L-shaped rod, with one side of the L-shape positioned in contact with the inner end of a rod-shaped member 112, and the other side of the L-shape positioned spaced apart from the contact plate 32. The contact plate 32 is plate-shaped and is attached to a plate material that forms the surface 111 of the board 11 in the hollow portion 12 inside the board 11, at a position spaced apart from the drive element 31.

[0041] When button 431 is pressed, the rod-shaped member 112 pushes one side of the drive element 31, causing the drive element 31 to rotate around the shaft member 33. The other side of the rotated drive element 31 comes into contact with the contact plate 32, and the sound-producing mechanism 30 produces sound when the drive element 31 and the contact plate 32 come into contact. The drive element 31 and the contact plate 32 are made of metal or wood.

[0042] In a modified version of Embodiment 1, a rhythm score is created in the same way as in Embodiment 1. The learner finds the language 53 corresponding to the musical note 51 or rest 52 of the rhythm shown by the rhythm learning tool 1a from the rhythm language list 100 shown in Figure 9, and applies the language 53 to the rhythm shown by the rhythm learning tool 1a. Then, while pressing the button 431 at a constant tempo to produce a sound, the learner pronounces the language 53 corresponding to the note value of the musical note 51 or rest 52. This allows the learner to learn rhythm while being aware of the beat.

[0043] [Embodiment 2] Next, the rhythm learning tool 1b according to Embodiment 2 will be described with reference to Figures 6 to 8. Figure 6 is a perspective view showing the rhythm learning tool 1b according to Embodiment 2. Figure 7 is a front view of the rhythm learning tool 1b of Embodiment 2. Figure 8 is a cross-sectional view of the note / rest display mat 26 of the rhythm learning tool 1b of Embodiment 2, taken along line BB. Hereinafter, as shown in Figures 6 and 7, the up-down direction and left-right direction are defined when the rhythm learning tool 1b is in use. The direction perpendicular to the up-down direction and left-right direction is defined as the front-back direction. In Embodiment 2, the same reference numerals are used for items similar to those in Embodiment 1, and their explanation is omitted.

[0044] The rhythm learning device 1b comprises a time signature indicator 10, a note / rest indicator 20, and a sound generation mechanism 30.

[0045] The time signature indicator 10 displays the time signature 41. As shown in Figures 6 and 7, in Embodiment 2, the time signature indicator 10 is a time signature display mat 16 that is rectangular in shape and has a joint portion 17 at least at the right end. There are several types of time signature display mats 16, and the time signature 41 is displayed on the surface 161 of each time signature display mat 16. Specifically, in Embodiment 2, as in Embodiment 1, in order to learn the basics of rhythm, each time signature display mat 16 displays the time signature 41 for the time signatures that are particularly basic, such as 2 / 4 time, 3 / 4 time, 4 / 4 time, 3 / 8 time, and 6 / 8 time, where the reference note that indicates the length of one beat is a quarter note or an eighth note. In addition, on the surface 161 of the time signature display mat 16, a first frame constituent line 426, which is part of the frame 42 that divides one beat indicated by the time signature 41, is displayed at the joint portion 17 at the right end.

[0046] The note / rest indicator 20 is used in combination with the time signature indicator 10 to display either a note 51 or a rest 52. The note / rest indicator 20 is roughly rectangular in shape and has a horizontal length that is a natural number multiple of the note value of one beat indicated by the time signature 41. The note / rest indicator 20 displays either a note 51 or a rest 52 corresponding to the note value indicated by the horizontal length of the note / rest indicator 20.

[0047] As shown in Figures 6 to 8, in Embodiment 2, the note / rest indicator 20 is a note / rest indicator mat 26 that is rectangular in shape and has a hollow section 28 and an air blowing nozzle 29 that communicates with at least one side (the front side in Embodiment 2) from the hollow section 28, and has joint sections 27 at at least the left and right ends. The note / rest indicator mat 26 has the same vertical length (front-to-back length) as the time signature indicator mat 16. There are multiple types of note / rest indicator mats 26, and the surface 261 of each note / rest indicator mat 26 displays various notes 51 or rests 52 necessary to form the basic rhythm in the time signature indicated by the time signature 41 displayed on the time signature indicator mat 16.

[0048] Furthermore, on the surface 261 of the note / rest display mat 26, second frame constituent lines 427, which form part of the frame 42 that divides one beat indicated by the time signature 41, are displayed at the upper and lower ends, excluding the joint parts 27, and third frame constituent lines 428, which form part of the frame 42 that divides one beat indicated by the time signature 41, are displayed at the left and right joint parts 27. The time signature display mat 16 and the note / rest display mat 26 are connected to each other by joining the joint parts 17 and 27. When the time signature display mat 16 and the note / rest display mat 26, or when the note / rest display mats 26 are connected to each other, the frame constituent lines 426, 427, and 428 become one, as shown in Figures 6 and 7, and a rectangular frame 42 is displayed on the surface 261 of the note / rest display mat 26. The frame 42 has dividing lines 421 that divide the inside of the frame 42 into upper and lower sections.

[0049] Furthermore, on the surface 261 of the note / rest display mat 26, a beat indicator 43 is displayed inside the frame 42. The beat indicator 43 is displayed above the dividing line 421 inside the frame 42. Preferably, the beat indicator 43 is displayed at the upper left end inside the frame 42. In Embodiment 2, the beat indicator 43 is shown as a black circle. The beat indicator 43 is not limited to a black circle; it may be any other shape, or it may be a design such as a metronome or castanets that makes the user aware of the beat.

[0050] When a note 51 or rest 52 displayed on the note / rest display mat 26 corresponds to the note value of one beat of the time signature 41, the note / rest display mat 26 has a horizontal length (left-right length) that serves as the basis for one beat. This horizontal length that serves as the basis for one beat is preferably such that, when the note / rest display mats 26 are joined together horizontally at the joint 27, a preschooler or a child in the lower grades of elementary school can step on one note / rest display mat 26 in one step. Furthermore, when a note 51 or rest 52 displayed on the note / rest display mat 26 corresponds to the note value of two or more beats of the time signature 41, the note / rest display mat 26 has a horizontal length that is the basis for one beat extended horizontally by the number of beats indicated by the note value. In other words, if the displayed note 51 or rest 52 indicates a note value of 2 beats in the time signature 41, the note / rest display mat 26 has a horizontal length that is twice the standard horizontal length of one beat. Also, if the displayed note 51 or rest 52 indicates a note value of 3 beats in the time signature 41, the note / rest display mat 26 has a horizontal length that is three times the standard horizontal length of one beat.

[0051] The note / rest display mat 26 has dividing lines 25 that separate each beat when there are two or more beats. That is, the note / rest display mat 26 is divided into sections of the same number of beats by the dividing lines 25. It is preferable that the dividing lines 25 are shown as lines different from the frame lines 426, 427, 4238 displayed on the time signature display mat 16 and the note / rest display mat 26, for example, dashed lines as shown in Figures 6 and 7, lines thinner than the frame lines 426, 427, 428, or lines of a different color from the frame lines 426, 427, 428.

[0052] Furthermore, the note / rest display mat 26, which displays notes 51 or rests 52 with a duration of two beats or more, displays a beat indicator 43 within each section separated by dividing lines 25. In addition, the note / rest display mat 26, which displays notes 51 or rests 52 with a duration of two beats or more, also has hollow sections 28 separated along with the dividing lines 25, and separate air blowing nozzles 29 are provided for each hollow section 28.

[0053] The notes 51 or rests 52 displayed on the note / rest display mat 26 are notes 51 or rests 52 that have a note value corresponding to the length of the beat indicated by the note / rest display mat 26. That is, in a time signature where one beat is a quarter note, for example, one quarter note or quarter rest will be displayed on the note / rest display mat 26 that has the horizontal length that is the standard for one beat. If an eighth note, which has half the note value of a quarter note, is to be displayed, two eighth notes will be displayed. The same applies when displaying triplets of eighth notes, sixteenth notes, dotted eighth notes, etc. Similarly, on the note / rest display mat 26 that has a horizontal length twice that of the standard for one beat, for example, if a half note, which has twice the note value of a quarter note, is to be displayed, one half note will be displayed. When displaying a dotted quarter note, since the dotted quarter note and eighth note together represent a two-beat duration, both a dotted quarter note and an eighth note are displayed. The same applies to the note / rest display mat 26, which has a horizontal length three times that of the standard horizontal length for one beat.

[0054] In the case of a note / rest display mat 26 that displays notes 51 or rests 52 with a duration of two beats or more, the note 51 or rest 52 is written within the section separated by the dividing line 25, in the section corresponding to the beat number on which the note 51 or rest 52 is inscribed. That is, the note 51 or rest 52 inscribed on the first beat is written in the first section from the left, the note 51 or rest 52 inscribed on the second beat is written in the second section from the left, and the note 51 or rest 52 inscribed on the third beat is written in the third section from the left.

[0055] The same applies to time signatures where an eighth note constitutes one beat. On a note / rest display mat 26 with a horizontal length that corresponds to the standard length of one beat, for example, one eighth note, one eighth rest, two sixteenth notes, etc. On a note / rest display mat 26 with a horizontal length twice that of the standard length of one beat, for example, one quarter note, a combination of a dotted eighth note and a sixteenth note, etc.

[0056] The sound-producing mechanism 30 is a mechanism that produces sound when force is applied to the beat indicator 43. In Embodiment 2, as shown in Figure 8, the sound-producing mechanism 30 consists of a hollow section 28 that contains air inside the note / rest indicator mat 26, and an air blowing nozzle 29 that releases the air from the hollow section 28 to the outside of the note / rest indicator mat 26. That is, when the note / rest indicator mat 26 is stepped on, the air contained in the hollow section 28 is released to the outside from the air blowing nozzle 29, and the sound produced when that air is released makes a sound. In the note / rest indicator mat 26 that displays notes 51 or rests 52 with a note value of two beats or more, the hollow section 28 is divided along with the dividing line 25, and a separate air blowing nozzle 29 is provided for each hollow section 28, so that when you step on each section divided by the dividing line 25, a sound is produced in each section.

[0057] The time signature display mat 16 and the note / rest display mat 26 are made of resin. The time signature 41, frame 42, beat indicator 43, note 51, and rest 52 are displayed by printing or other means on the surface 161 of the time signature display mat 16 or the surface 261 of the note / rest display mat 26. It is preferable that the time signature display mat 16 and the note / rest display mat 26 have an anti-slip surface on the back. This prevents the note / rest display mat 26 from slipping when walking on it, thus preventing falls and injuries.

[0058] The time signature display mat 16 and note / rest display mat 26 are used by joining together multiple arbitrary note / rest display mats 26 to the right of one time signature display mat 16 so that the rhythm corresponds to the time signature 41 displayed on the time signature display mat 16. In normal sheet music, vertical lines are displayed for each measure, but since arbitrary note / rest display mats 26 are joined together, vertical lines cannot be shown on the note / rest display mats 26. Therefore, in Embodiment 2, when vertical lines are needed, a black, elongated sheet, which is a vertical line sheet 46, is prepared as shown in Figure 7, and by placing the vertical line sheet 46 at the division of each measure, the measure can be made to be noticeable.

[0059] Next, with reference to Figure 9, the method of using the rhythm learning tool 1b will be described. Similar to Embodiment 1, the rhythm learning tool 1b is used together with a rhythm-language list table 100, which lists musical notes 51 or rests 52 that represent multiple basic rhythms, and language 53 that verbalizes the rhythms of the musical notes 51 or rests 52.

[0060] First, learners of rhythm, or instructors teaching rhythm to learners, create a musical score of the desired rhythm by connecting note / rest display mats 26 to the right of the time signature display mat 16 so that they correspond to various rhythms of the desired rhythm, each corresponding to the time signature 41. The rhythm to be learned could be, for example, the rhythm of a new piece of music to be played. Specifically, next to the time signature display mat 16 showing the time signature 41 of the desired rhythm, a note / rest display mat 26 showing the notes 51 or rests 52 that make up the desired rhythm is selected, and the joint section 27 of the note / rest display mat 26 is connected to the joint section 17 of the time signature display mat 16, or to the joint section 27 of the note / rest display mat 26 to its left, to create a musical score of the desired rhythm. To emphasize a measure, a vertical line sheet 46 is used, and the vertical line sheet 46 is placed at the end of a measure to create a musical score of the desired rhythm. For example, a rhythm like the one shown in Figure 7 can be created.

[0061] The learner finds the language 53 corresponding to the musical note 51 or rest 52 of the rhythm shown by the rhythm learning tool 1b from the rhythm language list 100 shown in Figure 9, and applies the language 53 to the rhythm shown by the rhythm learning tool 1b. Then, while applying pressure to the beat indicator 43 at a constant tempo to produce a sound, the learner pronounces the language 53 corresponding to the note value of the musical note 51 or rest 52. In Embodiment 2, since a sound is produced by walking while stepping on the beat indicator 43, the learner pronounces the language 53 corresponding to the note value of the musical note 51 or rest 52 while walking while stepping on the beat indicator 43 at a constant speed. This allows the learner to learn rhythm while being aware of the beat.

[0062] As described above, the rhythm learning tools 1a and 1b of the present invention are equipped with a beat indicator 43 that makes the user aware of the beat, and a sound-producing mechanism 30 that produces a sound when force is applied to the beat indicator 43. This allows the user to visually perceive the beat indicator 43 and become aware of the beat with their eyes. In addition, since a sound is produced when force is applied to the beat indicator 43, the user can become more strongly aware of the beat by listening to the sound while applying force to the beat indicator 43 themselves, rather than passively listening to the sound of a metronome or the like. Then, by becoming aware of the beat through three points—the eyes, the action of applying force, and the sound produced by the action—and by speaking the language 53 that verbalizes the rhythm indicated by the musical notes 51 or rests 52, the user can learn accurate rhythm while being aware of the accurate beat.

[0063] Furthermore, in the rhythm learning tool 1 of the present invention, the beat indicator 43 is displayed at the upper left end inside the frame 42 that divides one beat. As a result, the beat indicated by the beat indicator 43 can make the user aware of the start of sound production and the start of conducting, allowing them to learn rhythm while feeling the beat more strongly.

[0064] Although embodiments of the present invention have been described above, the present invention is not limited to the above embodiments, and various modifications are possible without departing from the spirit of the invention.

[0065] For example, in Embodiment 1 above, the rhythm learning tool 1a is composed of a board 11 and a card 21, with a frame 42 displayed on the board 11. In Embodiment 2 above, the rhythm learning tool 1b is composed of a time signature display mat 16 and a note / rest display mat 26, with a frame 42 displayed on the note / rest display mat 26. However, the present invention does not necessarily have to be configured in this way. For example, in the rhythm learning tool 1 of Embodiment 1, the frame 42 may not be displayed on the board 11, but on the card 21. Similarly, in the rhythm learning tool 1b of Embodiment 2, the time signature display mat 16 may be made large enough to accommodate the note / rest display mat 26 side by side, the frame 42 may be displayed on the time signature display mat 16, and the note / rest display mat 26 may be placed inside the frame 42. The configuration is not limited to this example; the time signature indicator 10 and the note / rest indicator 20 can be configured in any way as long as, when the time signature indicator 10 and the note / rest indicator 20 are combined, a frame 42 that divides one beat indicated by the time signature 41 and a beat indicator 43 that shows the beat are displayed inside the frame 42. [Industrial applicability]

[0066] The rhythm learning device and rhythm learning method of the present invention enable rhythm learning while being aware of the beat, and since they can be used by learners acquiring musical skills, they have potential for industrial application. [Explanation of Symbols]
