Definition

A 'cantus firmus' is a pre-existing melody used as the foundation for a polyphonic composition.

Composers weave new melodic lines around it, creating complex harmonies. It's like building a musical skyscraper on a solid foundation. Unlike a solo piece, the 'cantus firmus' supports and interacts with other melodies.

Etymology

It originated in the medieval period as composers started developing polyphony. The term emphasized the stability of the core melody.
