Here is a newbie (n00b) question:
Do all piano compositions have voices? I would assume that if both hands are used to play notes, then that piece has two voices.
Anyone want to clarify?
Some pieces have just one voice like a violin/cello/voice solo with accompaniment (Chopin nocturne op. post. in C# minor or Chopin etude op25 no7).
Some pieces aren't fugues but are composed SATB, like a string quartet (Beethoven piano sonata #16, last movement, introduction)
In these, you can clearly hear the individual voices (melodies) in contrast to any accompaniment, which tends to be less melodic and more harmonic (chordal).
