When does polyrhythm occur?

When does polyrhythm occur?

• A. When only one rhythmic pattern is present.
• B. When tempo changes rapidly.
• C. When two conflicting rhythmic patterns are present simultaneously.
• D. When the harmony changes on every beat.

Answer: (C)

Polyrhythm is when two or more rhythmic patterns are played at the same time, creating simultaneous patterns that don’t share a simple one-to-one subdivision. A classic example is three notes played in the time another voice plays two notes—three against two—so the two rhythms line up only at longer intervals. This simultaneous coexistence of different rhythmic groupings is what defines polyrhythm. So, having two conflicting patterns present at the same moment fits the idea of polyrhythm. Tempo changes would alter speed, not the coexistence of rhythms. Harmony changing on every beat concerns chords, not rhythmic structure. And a single rhythmic pattern, even repeated, is monorhythm, not polyrhythm.
