Accordion/Right hand (Diatonic button accordion)



A diatonic button accordion is a type of button accordion where the right keyboard only has the notes of diatonic scales in a small number of keys. The left, or bass side, usually contains the main chords of the instrument's key and their root notes.

Because diatonic accordions have only a few keys they can play in, and usually cannot play accidentals, they are very restricted in what they can play. Usually they can only play folk music and classical music that doesn't contain many accidentals or changes of key signature.
