Fugue in G major BWV 577 (Bach)

The piece is often referred to as the "Gigue" fugue. It earned this moniker because its lively subject is written in a compound meter (usually 12/8 time) that resembles the baroque dance form of the same name. The cheerful, bouncing rhythm makes it one of Bach's most accessible organ works.

While traditionally catalogued under Bach's name, some musicologists have debated whether he actually composed it. The piece's unusual structure has led scholars to suggest it might have been written by one of his sons or a contemporary. However, it remains officially cataloged as a Bach composition.

BWV 577 is explicitly written for the pipe organ, requiring a pedalboard to play the bass notes. The lively tempo and rhythmic drive make it an excellent showcase for an organist's agility on the pedals. It is a standard repertoire piece for organ recitals and church services.

The fugue is written in G major, a bright and triumphant key in the Baroque era. Because it is written for organ, performers must use specific registrations (combinations of organ stops) to bring the joyful melody to life. This typically involves using principal stops to create a loud, clear tone.
