If I have a single melodic line and have staccato 1/16th notes playing just the tonic of the key behind my melody with another instrument, would that be considered a heterophonic texture? What I mean is, are the 16ths notes considered a melodic variation of my original melody (heterophonic), are they forming a harmonic accompaniment (homophonic), or are the 16th notes more of a pedal tone (biphonic). Is it something totally different?
I'm trying to learn my various musical textures and want to make sure I am using the correct terms. Hope the question makes sense?
