An accordion is like a breathing creature: it howls, shouts, sighs, gasps, whispers.
The accordion takes its name from its left side. With the exception of the first row, the ground basses, every button does not give one tone there, but immediately a whole chord. The accordionist cannot see his bass buttons, the left hand plays by touch. Grondbas C is the only one with a dimple in the bud.
The accordionist plays the melody with the right hand, via the white and black keys of a keyboard or – on a button accordion – via ingeniously grouped round buttons.
Which buttons and keys does an accordion have?
The ground basses are arranged on the basis of the circle of fifths. The rows of buttons next to it – called standard basses – consecutively give a major and a minor chord, a dominant seventh chord and a diminished seventh chord on those root notes.
The number of standard basses indicates the size of an accordion: from 24 bass accordions to the largest variants with 96 or even 120 basses. The weight of an accordion can vary from 4 to 14 kilos.
