A sonata is a specific form of musical composition that typically consists of three main sections: exposition, development, and recapitulation. It is usually characterized by its use of themes and motifs that are developed and transformed throughout the piece. Sonatas can be written for solo instruments or for small ensembles, and they can be in any key and time signature.
