Well.. i think that all of them could be answers. For example, in ravel`s bolero you can hear that there is a parallel discourse at various instruments.. but in other orchestral works there are musical lines that are in opposite ways. in Debussy`s piano works the typical harmony is parallel. but i am saying that all of the answers could be good because it did not matter the way of the musical "motions", but the result. the harmony used in many of debussy`s works is called the gravitational system, and it can be seen in his preludes, and of course the interaxial system which principals are that every sound has it`s own axe, and all the chords are major.. the movement of the voice was irrelevant, but the harmony is.
