It is with increasing astonishment that I learn what you think I have been saying, Robin. If I have ever said anything to cause you to believe that I object to anything of the sort, then I apologise abjectly, and must insist that my position is quite the opposite. You are perfectly correct to say that I understand the importance of the inserts in Zeitmasze, though I am afraid I am going to have to take issue once again by pointing out that Stockhausen had been using inserts (for exactly that same reason) for some time before that work: at least as early as Kontra-Punkte, in fact (and I do wonder how much influence Cage may have had on that composition). I do look forward to reading the chapter on Whitehead, from a book that has up until now escaped my attention.
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!
