Don't describes a round: It is a term used interchangeably with monophony, Voices enter in succession with varied melodies.
Explanation:
Round can also be called a perpetual or infinite canon. This is because it is a type of canon that allows a group of voices (usually 3) to enter the song in successive ways while they sing the same melody in unisoto. Each voice, within the round, can restart whenever its line within the melody is finished, thus generating a harmonious and melodious cycle.
Because it is a type of canon, the round is a strictly imitative form. In addition, it provides a playful characteristic to the melody that is much appreciated today.
