A Rondellus is a round; a rota is a canon at the unison. The rondellus is much the senior of the two, though in some of its moods it does not at all behave like a venerable relic of the Middle Ages. But that is what it is, and in its early life it had a respectable place in the music of the church. It is true that during some of that time one might have heard rounds sung in every ale-house, but if so nobody bothered to write them down, and the first printed collection is no earlier than 1609.
