Fugue

A fugue is a polyphonic musical form based on the principle of imitation. It typically begins with a main theme (the subject) introduced by one voice, then repeated and developed by other voices in an interwoven texture. Each voice maintains its own melodic and rhythmic independence, resulting in a complex and structured composition. Made famous during the Baroque era by composers like Johann Sebastian Bach, the fugue is a highly disciplined form often studied in classical composition.
