I’m looking for the term for the study of rhythm andthe role and rhythm of each voice in multi voice composing. For example “lead part/voice/melody or supporting part/voice/melody”. By rhythms what I mean is the length of the notes usually used in each role (say whole and half notes for the supporting voice and an eighth sixteenth and quarter notes for the lead part). Texture seems to be close to what I’m speaking of, but I’m still not sure if I’ve come across a specific theorist that covers this.
I’m currently studying part writing & voice leading, counterpoint, texture (monody, polyphony, homophony) etc. I’ve done plenty of research in each but I still haven’t come across exactly what I want to study within these ideas.
