I suppose that the point of these pieces, if they have one, is that one uses as much or as little of each, in whatever order one likes. One can use them "as is" - long ambient repetitive pieces (up to a total of 200 minutes) - or not. I wrote them to listen to myself, with little thought to anybody else. Piano is good, as is player piano or piano playing software. Piano is best, of course.
