Inmusic,homorhythm (alsohomometer) is atexture having a "similarity of rhythm in all parts"[2] or "very similarrhythm" as would be used in simplehymn orchorale settings.[3] Homorhythm is a condition ofhomophony.[2] 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 isheterorythmic orheterometric.
The term is used for compositions in which all the voice-parts move simultaneously in the same rhythm, forming a succession of chords.[4][5] It may also be calledchordal style,familiar style,note-against-note style,isometric, andhomophonic.[3]Isometric may used to refer to music in which each vocal part has the same number of syllables, withisorythmic being used to refer to music in which each voice has the same rhythm.
Isometre is the use ofpulse without regularmeter. The music is used in thepsalmsongs of theOrthodox Reformed Churches in the Netherlands, based on the rhythm made byPetrus Datheen (16th century), as well as some other churches.[clarification needed] Isometric music may be homometric music or music in which each vocal part has the same number of syllables, withisorythmic being used to refer to music in which each voice has the same rhythm.
