Classical accordion is the use of the concert accordion (often a free-bass “convertor” accordion or Russian bayan) as a fully fledged classical instrument in solo, chamber, and concerto settings. Unlike folk, pop, or musette traditions, the classical accordion employs a free-bass left hand capable of single-note lines and full polyphony, allowing true four-part counterpoint and organ- or keyboard-like textures. The instrument’s bellows enable uniquely elastic phrasing and long, organ-like sustains, while registrational changes supply a palette ranging from reedy delicacy to orchestral weight. The repertoire spans baroque and romantic transcriptions, 20th‑century modernism, and a rich body of late‑20th and 21st‑century works written specifically for the instrument, frequently exploring extended techniques (bellows shakes, air-button noises, key/percussion effects) and, in contemporary settings, electronics.
