Which term denotes a shift in the rhythmic pulse from division of 2 to division of 3, such as 6-8 into 3-4?

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

Answer: (C)

The key idea here is a rhythmic shift called a hemiola. It happens when the subdivision of the beat changes feel—from grouping in two to grouping in three (or vice versa) within the same span of music. For example, in a measure that’s normally heard as 6/8, you typically feel two main pulses beacuse the eight-notes are grouped as two sets of three. A hemiola temporarily reinterprets that same material so it comes across as three pulses (like a 3/4 feel) over the same length of time, or the reverse. So the passage that could be heard as two groups of three eighths ends up feeling like three groups of two, creating a distinct shift in the pulse. That’s why this term fits the idea of moving from division of 2 to division of 3, such as 6–8 into 3–4. The other terms refer to different concepts: a minuet is a dance style often in 3/4; rubato is flexible, expressive timing; and sotto voce means playing softly.
