Accordion pertains to a hand-held musical wind instrument that is made of bellows attached to two rectangular frames on which buttons are mounted and, on some models, keys resembling piano keys.

The accordion is played by pushing in and pulling out the bellows. This action forces trapped air to pass over metal tongues called reeds. This flow of the air makes the reeds vibrate and produce sound.

There are two (2) different types of accordions:
1. Diatonic accordion also called double-breathed enables two related notes to be played by pressing the same button. One note is produced when the bellows is compressed and the other when it is enlarged; and
2. Chromatic accordions produce the same note during both compression and expansion of the bellows. The most widely used chromatic accordion is the piano accordion, which has a keyboard like a piano in place of the right-hand buttons.
