Definition: A rhythmic device where two groups of three beats are replaced by three groups of two beats (or vice versa), giving the effect of a shift between triple and duple meter.
The Savvy Take: This is the classic “1-2-3, 1-2-3” becoming “1-2, 1-2, 1-2.” It creates a braking effect, often used by Brahms and Baroque composers to signal the end of a phrase. Lean into that drag!
