In Depth

The accordion produces sound when air from the bellows passes over metal reeds.‍​‌​‍​‍​‍​‍​‍​‍​‍​‌​‌​‌​‍​‌​‌​‍​‌​‍​‌​‌​‍​‍​‌​‌​‌​‌​‍​‍​‍​‌​‍​‍ The player compresses and expands the bellows while pressing keys or buttons, and different instruments use different button layouts — the piano accordion has a keyboard on one side, while button accordions use a grid system. Originally developed in early 19th-century Vienna, the accordion became central to folk music traditions worldwide. It is essential in French musette, Argentine tango, Cajun music, and Tex-Mex conjunto. Despite its association with folk genres, the accordion has found a place in contemporary classical and experimental music.
Did you know?

The accordion was banned from the concert hall for decades because critics considered it a street instrument. It wasn't until the mid-20th century that serious composers began writing for it.
