What describes a countermelody?

A countermelody is defined as a second melody that harmonically complements and contrasts with the main melody. It can be played above or below the primary melody, enriching the overall texture of a musical piece. This interaction provides depth and complexity, allowing for a more intricate musical dialogue.

For example, in a piece for two instruments, one might play the main melody while the other plays the countermelody, creating a layered effect where both melodies are distinct yet interdependent. The countermelody does not simply repeat the main melody or serve only as an accompaniment; rather, it exists as a separate musical idea that interacts with the primary tune, enhancing the listener's experience.

This distinction is crucial in understanding how melodies can work together in a composition, adding to the emotional and artistic expression of the music.
