What is a "concertina"?

A concertina is a small, hand-held accordion-like instrument with a hexagonal or oval shape. It consists of a set of metal reeds inside a bellows. When the bellows are pushed or pulled, air flows through the reeds, creating sound.

Concertinas are used in various musical styles, including folk, traditional, and classical music, and are known for their distinct, expressive sound and portability.
