Chromatic Accordion Musical Instrument for Versatile Music Applications

The accordion is a musical instrument in which the source of sound is steel tongues riveted to metal strips and vibrating under air pressure in the corresponding openings of the strips. In the accordion's construction, it is possible to distinguish right and left sections connected by furring. The right section of the accordion contains a box and a fingerboard with a button-type keyboard.

The box contains the right deck, resonators, valves and registers. To the right box there are straps that hold the harmonica on the musician's shoulders, as well as a grille. The left section of the harmonica also consists of a box in which the left deck, resonators, mechanics and keyboard for the left hand are mounted.

The left keyboard contains three rows of buttons, which alternate bass keys with chord keys. The left section has a strap worn on the left hand to control the furry chamber.
