An accordion key is a type of button or lever that is used to play an accordion. When the key is pressed, it opens a valve that allows air to flow into the accordion’s bellows. This air is then used to create sound by vibrating the accordion’s reeds. Accordion keys are typically made of plastic or metal, and they can be either round or square. They are usually arranged in a chromatic order, with the white keys representing the natural notes and the black keys representing the sharps and flats.

Accordion keys are an important part of the instrument, and they must be in good working order for the accordion to play properly.
