What is a round in music?

A round is a musical composition that features two or more voices singing the same melody, but starting at different times. As each voice completes the melody, they begin again, creating a perpetual cycle of overlapping harmonies. Rounds are typically short and easy to sing, making them popular in group singing settings such as choirs and camps. Some famous examples of rounds include "Row, Row, Row Your Boat" and "Frère Jacques." Rounds can be used as a warm-up exercise or as a musical performance piece.
