In music, variation is a formal technique where material is repeated in an altered form. The changes may involve melody, rhythm, harmony, counterpoint, timbre, orchestration or any combination of these.

Variation is often contrasted with musical development, which is a slightly different means to the same end. Variation depends upon one type of presentation at a time, while development is carried out upon portions of material treated in many different presentations and combinations at a time.^[1]
