A '''fugue''' (from Italian "fuga," or flight) is often described as "a movement of continuity" or a piece that focuses on both musical technique and musical texture. The fugue is based on strict rules of [[counterpoint]], which flourished in German music of the 18th century, but has been used since then as a vehicle for elevated emotions. [[J.S. Bach]] is considered the master of the fugue, and fugues also played an important role in the late works of [[Beethoven]] and [[Shostakovich]].

A '''fugue''' (from Italian "fuga," or flight) is often described as "a movement of continuity" or a piece that focuses on both musical technique and musical texture. Generally speaking, the fugue is not considered a musical structure because it is infinitely variable. It is rather a style or method of [[counterpoint|contrapuntal]] writing which may or may not be distinguished into finite sections. The fugue is based on strict rules of counterpoint, which flourished in German music of the 18th century, but has been used since then as a vehicle for elevated emotions. [[J.S. Bach]] is considered the master of the fugue, and fugues also played an important role in the late works of [[Beethoven]] and [[Shostakovich]].
