Thanks so much for the clarity Jerry. I did not quite catch the title in my interview with Mary, and she couldn't recall the author's name - so you have now explained both and this will send me on a mission to read it. Certainly the ideas left a lasting impression on Mary. I asked her to autograph my copy of her book, which she did with the inscription '1 + 1 = 3'
I feel that it could be useful to have a discussion-forum on the music of Stockhausen. There are so many people from all over the world, young and old, learned and eager to get into contact with this musical world: musicologists, composers, musicians, music lovers; people who plan concerts - who write books or have to give lectures and so on. So there should be much stuff, many ideas that we can share. And when we have open questions, there may be people who studied just that and could give a hint or a stimulus.
A problem might be the English language, but i feel that is the only possibility that many people who are interested can participate. And we can exercise tolerance to mistakes!
