In music, homophony (/həˈmɒf(ə)niː,hoʊ-/;[1][2], Greek: ὁμόφωνος, homóphōnos, from ὁμός, homós, "same" and φωνή, phōnē, "sound, tone") is a texture in which a primary part is supported by one or more additional strands that provide the harmony.[3] One melody predominates while the other parts play either single notes or an elaborate accompaniment. This differentiation of roles contrasts with equal-voice polyphony (in which similar lines move with rhythmic and melodic independence to form an even texture) and monophony (in which all parts move in unison or octaves).[4] Historically, homophony and its differentiated roles for parts emerged in tandem with tonality, which gave distinct harmonic functions to the soprano, bass and inner voices.
A homophonic texture may be homorhythmic, which means that all parts have the same rhythm.[5][6]Chorale texture is another variant of homophony. The most common type of homophony is melody-dominated homophony, in which one voice, often the highest, plays a distinct melody, and the accompanying voices work together to articulate an underlying harmony.[7]
Initially, in Ancient Greece, homophony indicated music in which a single melody is performed by two or more voices in unison or octaves, i.e. monophony with multiple voices. Homophony as a term first appeared in English with Charles Burney in 1776, emphasizing the concord of harmonized melody.[8]
