Accordion
From Wikipedia, the free encyclopedia
An accordion is a musical instrument that has keys similar to a piano, but is small enough for a person to hold, and 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 invented in 1822 in Germany by Friedrich Buschmann.[1]
