Diatonic button accordion

A diatonic button accordion is a type of button accordion where the melody-side keyboard is limited to the notes of diatonic scales in a small number of keys (sometimes only one). The bass side usually contains the principal chords of the instrument's key and the root notes of those chords.

Some diatonic button accordions (e.g.: melodeon) are bisonoric, meaning each button produces two notes: one when the bellows is compressed, another while it is expanded; other instruments (e.g.: garmon')are unisonoric, with each producing the same note regardless of bellows direction; still others (e.g.: schwyzerörgeli, trikitixa) have a combination of the two types of action.
