Hemiola

About Hemiola

Hemiola is a rhythmic device where a passage in triple meter is temporarily felt as duple, or vice versa — without the time signature actually changing. In 3/4, a hemiola groups two bars into three sets of two beats (2+2+2) instead of the usual three sets of three (3+3+3). The effect is a momentary metric displacement — the music seems to slow down or regroup before resolving back to the original meter. It's common at cadences in Baroque and Classical music.
