Chaconne

A musical variation form built over a recurring harmonic progression or bass pattern. Its repeating foundation supports successive changes in melody, texture, rhythm, and instrumentation.

Ground bass: A bass line repeated throughout a composition, often supporting variations above it. A recurring bass line is one foundation on which a chaconne can build.
Baroque music: European art music from about 1600 to 1750, marked by elaborate counterpoint and expressive contrast. The chaconne became a prominent instrumental form during the Baroque era.

Passacaglia: A variation form commonly built over a repeating bass or harmonic pattern. The passacaglia is the closest formal counterpart, and the names sometimes overlap in historical usage.
Harmonic progression: A sequence of chords that shapes a passage’s tonal movement. Some chaconnes repeat a chord sequence rather than a fixed bass melody.

Theme and variations: A musical form in which a stated theme is followed by altered versions. Unlike many chaconnes, this form need not preserve a repeating bass or chord sequence.
Variation: A compositional process that alters musical material while preserving recognizable features. Each new passage transforms the chaconne’s recurring foundation.
