An accordion is a musical instrument that has keys similar to a piano, but is small enough for a person to hold. It makes sounds using air pushed and pulled through reeds using a bellows. The accordion can also have buttons instead of keys. The 6-plus-6-system with three rows has the same fingering in all twelve scales.
The accordion was first patented in 1829 in Austria by Cyrill Demain.
