Description

Technical Field

[0001] The utility model relates to the field of wind instruments, in particular to a multi-faceted tonality delta blues harmonica. Background Art

[0002] There are 12 general harmonica tones, arranged from low to high: G, #G, A, bB, B, C, #C, D, bE, F, #F, and 14 special tones plus LOW F, which is lower than G, and HG, which is higher than #F. Each harmonica has a different tone. The most commonly used harmonica on the market is C tone, which is neither high nor low, suitable for playing most songs; G tone is like a low cello sound, suitable for playing sad songs; A tone has a more blues style, and is somewhat like saxophone sound; the clear F tone takes you into a fairy tale world; bE and bB remind people of the joy and hesitation of a violin; many modern pop music is suitable for playing in D tone... Each tone plays a different flavor of music. Since a blues harmonica can only play a limited number of chords in one tone, many harmonica friends will buy multiple harmonicas of different tones. Utility Model Content

[0003] In view of the problem that "a blues harmonica can only play limited chords in one tonality" in the prior art, the utility model provides a multi-faceted tonality delta blues harmonica, which is convenient for changing tonality while arranging the tonality of each face according to the commonly used Ⅱ-Ⅴ-Ⅰ of jazz-style music, so as to facilitate playing chords of all levels through the multi-hole blowing and suction technology and the conversion face method; at the same time, "two five one" can also be regarded as the dominant key Ⅴ-Ⅰ-Ⅳ, so that one harmonica can play the traditional 12-bar blues commonly used chord progressions Ⅰ-Ⅰ-Ⅰ-Ⅰ, Ⅳ-Ⅳ-Ⅰ-Ⅰ, Ⅴ-Ⅳ-Ⅰ-Ⅴ and other chord progressions. At the same time, the resonance cavity of the utility model is larger than that of the traditional blues harmonica, and the box reverberation is fuller.

[0004] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0005] The multi-faceted tonality delta blues harmonica comprises a fret, two reed plates, two cover plates and docking screws. The fret is arranged between the two reed plates, and the two cover plates are respectively located above and below the two reed plates. The docking screws lock the cover plates, the reed plates and the fret into one. The fret, reed plates and cover plates are assembled into a body with a polygonal structure, and each side is provided with a plurality of sound holes. The tonality of the sound holes on each side of the body is different, and sound holes are provided in the center of the fret and reed plates.

[0006] A further improvement is that the sound hole opened in the center of the cover plate can be used to install a "kazoo" membrane to further enrich the tone.

[0007] A further improvement is that a rotating shaft is connected to the sound hole of the fret, and the upper and lower ends of the rotating shaft extend out of the sound hole of the cover plate. The rotating shaft is rotated to facilitate switching the mouthpiece surface of the piano body.

[0008] A further preferred solution is that the piano body is an equilateral triangle, each side has ten sound holes, the order of the blowing notes from left to right is 1, 3, 5, 1, 3, 5, 1, 3, 5, 1, and the order of the inhaling notes from left to right is 2, 5, 7, 2, 4, 6, 7, 2, 4, 6, that is:

[0009] .

[0010] A further improvement is that the three sides of the piano body are in the tonality of G, C and F. The second position tonality DGC is transposed, which is convenient for playing the 12-bar blues in the key of G.

[0011] A further improvement is that the three sides of the piano body are in the tonality of D, G and C. The second position tonality ADG modulation is convenient for playing the 12-bar blues in the key of D.

[0012] A further improvement is that the three sides of the piano body are in the tonality of A, D and G. The second position tonality EAD is transposed, which is convenient for playing the 12-bar blues in the key of A.

[0013] A further improvement is that the three sides of the piano body are in the key of E, A and D. The second position key BEA is changeable, which is convenient for playing the 12-bar blues in the key of E.

[0014] A further improvement is that the three sides of the piano body are in the key of B, E and A. The key of the second position is F#-BE, which is convenient for playing 12-bar blues in the key of B.

[0015] A further improvement is that the two spring plates are respectively a whole spring plate or composed of three sub-block spring plates. A whole spring plate is convenient for production; a sub-block spring plate is convenient for performers to replace the spring plates they need according to their personal preferences in actual use. Beneficial Effects

[0016] The harmonica of this structure forms a multi-faceted tonal playing mouth, one instrument has multiple tones, and the switching is free. The harmony of a single instrument body is rich and complete, and the playing style is unique. The resonance cavity of the instrument is large, and the reverberation of the box is fuller.
