Canon (music)

For other meanings of the word "canon" see canon.

A canon is a piece of voices (or instrumental parts) that sing or play the same music starting at different times. A round is a type of canon, but in a round each voice, when it finishes, can start at the beginning again so that the piece can go “round and round”. Perhaps the most well-known canon is the Pachelbel Canon written by Johann Pachelbel.
