Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of harmonica manufacturing, and relates to a single-row 36-hole full-pitch harmonica with a semitone alternation arrangement structure. BACKGROUND

[0002] The traditional harmonica has the following defects:

[0003] 1. Fixed key: Single-row multi-hole harmonicas and diatonic harmonicas are fixed in key, and when playing, different harmonicas need to be matched to play complex pieces when transposition or modulation is required.

[0004] 2. Complex semitone operation: the semitone scale (such as Hohner Chromonica) needs to switch semitones through side sliding keys, which destroys the continuity of playing.

[0005] 3. Unordered scale arrangement: the high and low arrangement of the scale is unordered, and the playing logic is unclear, such as the following three common types:

[0006] 1. Duet harmonica -- 24-hole general solo arrangement

[0007] Tablature scale:
