Concertina

A concertina is a portable, accordion-like musical instrument with push or pull buttons on both ends, allowing players to produce sound by expanding or contracting the flexible, bellows-like middle. Its buttons open different reeds inside, creating musical notes. The concertina is valued for its compact size, versatility, and expressive range, making it popular in folk, traditional, and even some classical music. Its unique design allows for a variety of playing styles, and it can be played solo or as part of ensemble, offering a distinctive sound characterized by rhythmic bellows movement and melodic complexity.
