Which term is used to describe the repetition of a musical piece?

The term "reprise" is used to describe the repetition of a musical piece. In musical terminology, a reprise refers specifically to the return of a theme or melody that has been presented earlier in the composition. This technique helps to create cohesiveness within a piece, allowing listeners to connect with earlier material, and often adds to the overall emotional impact of the music. Reprises are common in various genres of music, including classical works, musicals, and popular songs, where they serve to reinforce key motifs or sections.

The other terms do have their own meanings, but they are not typically used to describe the repetition of a musical section in the same context as a reprise. "Cycle" may refer to a series of events or thematic elements, but it does not highlight the specific act of repetition in music. "Echo" implies a reverberation or a sound bouncing back rather than a direct repeat of a musical phrase. "Rewind" generally refers to going back to an earlier point in time or playback, particularly in media formats, but it does not denote the musical repetition itself. Hence, "reprise" is the most accurate term for this concept in music.
