There is a sense in which after much complex art, much elaborate art, much sermonizing art of the sort I was talking about earlier, people sometimes get the urge to simplify things down and in a sense they say let's go back to the five finger exercise, let's see what a note on the piano sounds like instead of playing, you know, Chopin or Stravinsky all the time, let's remind ourselves what the actual note sounds like, or two notes together, or one note and then a gap and then another note, and you suddenly become aware of the richness, in a sense in these very simple elements.
