Polymeter is defined as which of the following?

• A. When two or more meters operate simultaneously.
• B. When different meters alternate irregularly.
• C. When rhythm is syncopated.
• D. When tempo changes within a measure.

Answer: (A)

Polymeter is when two or more meters operate simultaneously. Each part or instrument keeps its own metric structure, so you might hear a 3/4 pattern layered with a 4/4 pattern at the same time. They align only at points dictated by the least common multiple of their beat counts—for example, 3/4 over 4/4 line up every 12 quarter notes (four measures of 3/4 equal three measures of 4/4). This simultaneous use of different meters creates a layered, cross-rhythmic feel. The other ideas describe different concepts: alternating meters would mean switching between meters rather than running them together; syncopation is about shifting accents within a single meter; tempo changes within a measure involve changing speed, not changing the underlying meter.
