There are more precise terms which describe the number and relationships between voices:
- Monophony (base musical texture) is music with just one part (such as Gregorian chant).
- Heterophony is a kind of complex monophony - there is only one melody, but multiple voices each of which play the melody differently.
- Polyphony is music with several parts, each independent but related and each as important as the others - none of them is merely accompaniment.
- Homophony is music in which the top part has a dominant melody and other parts are subservient to it, moving in the same, or nearly the same, rhythm.
- Monody is 17th century Italian song with a dominant melody and a separate accompaniment.
Note that none of these terms accurately describes the majority of western music made today, featuring a melody and rhythmically free accompaniment; in homophony the accompaniment is not rhythmically free, and monody is typically used in a historically specific way.
A simultaneity is more than one complete musical texture occurring at the same time, rather than in succession.
A more recent type of texture first used by György Ligeti is micropolyphony. Other textures include homorhythmic, polythematic, polyrhythmic, onomatopoeic, compound, and mixed or composite textures (Corozine 2002, p.34).
