In music, homorhythm (also homometer) is a texture where there is a "sameness of rhythm in all parts" or "very similar rhythm" as would be used in simple hymn or chorale settings. Homorhythm is a condition of homophony. All voices sing the same rhythm. This texture results in a homophonic texture, which is a blocked chordal texture. Homorhythmic texture delivers lyrics with clarity and emphasis. Texture in which parts have different rhythms is heterorythmic or heterometric.
The term is used for compositions in which all the voice-parts move simultaneously in the same rhythm, forming a succession of chords. It may also be called chordal style, familiar style, note-against-note style, isometric, and homophonic. Isometric may used to refer to music in which each vocal part has the same number of syllables, with isorythmic being used to refer to music in which each voice has the same rhythm.
