What is the difference between a round and a canon?

Answer 1

A canon is a song in which different parts, starting at different times, sing the same thing and do not repeat. A round is a song in which different parts start at different times but sing the same thing multiple times.

Answer 2

A round is a musical composition in which two or more voices sing exactly the same melody (and may continue repeating it indefinitely), but with each voice beginning at different times so that different parts of the melody coincide in the different voices, but nevertheless fit harmoniously together.

A round is a type of canon.

Canons imitate but occasionally do not duplicate the lead.

Answer 3

No, the word round has many definitions and many synonyms, but canon is not one of them.

Actually, in musical terms, a round is a type of canon. So the answer is 'yes'.
