I consider the first 20 performances just learning the piece. Think about it this way: If you think about a pianist who plays a Schubert sonata through his whole lifetime - if you listen to Rubenstein or Horowitz playing their repertoire later in their life, you understand the richness with which they play that music, and how differently they must have played it when they were younger.
Philip GlassI was a regular kind of academic music student. I was at Juilliard. I had to study all the contemporary music of the time, and changing that language very radically was just a sign or a signal that I was going to try to do something very different. I find that that's what I feel closest to. I found no real inner response in me in a non-tonal language.
Philip GlassI don't think I'm capable of making radical changes, but over a period of four or five years you can perceive very big changes, and they seem rather small at the time.
Philip GlassMy biggest problem about writing is whenever I write piano pieces, because I then have to learn to play them, which is sometimes not so easy.
