What term describes a musical form based on imitation and a round, where a single tune is sung by others entering at different times?

• A. Fugue
• B. Canon (round)
• C. Imitation
• D. Round

Answer: (B)

A canon, especially a round, is built on exact imitation with staggered entrances. One voice (or a group) sings a tune, and other voices begin the same melody after a fixed interval, producing overlapping lines that fit together like a loop. That repeated, imitated entry is the hallmark of a canon, and when it’s arranged as a round, the same tune can continue looping as new singers join in at regular gaps. A familiar example is a round you can sing in groups, where everyone sings the same melody in succession and the piece can go on indefinitely. This differs from a fugue, which also uses imitative entrances but develops the material with subject entries, countersubjects, and episodes rather than a simple cyclic repetition. Imagination of the term “imitation” by itself lacks the formal structure, while a round captures the cyclic, round-like repetition; naming it canon (round) precisely signals both the imitation and the looping, staggered entrances.
