Which term describes a shift from two to three or vice versa?

• A. Rubato
• B. Hemiola
• C. Smorzando
• D. Sotto voce

Answer: (B)

Hemiola captures a moment when the sense of meter shifts between two-beat grouping and three-beat grouping, creating a 3:2 cross-rhythm. In other words, three notes are heard in the time usually occupied by two, or two notes are heard in the time of three. This produces a temporary restructuring of the beat—two pulses can feel like three, or three can feel like two—often spanning barlines to emphasize the change. This rhythmic device adds a natural tension and forward drive by altering how the ear perceives the beat, rather than simply changing tempo or dynamics. The other terms describe expression or dynamics rather than a change in how the beat is grouped, so they don’t describe this rhythmic shift.
