This was (and is) a hard piece for me to get into totally. The earlier recording on Nonesuch was never that enjoyable to me since it just seemed so chaotic with all the clapping at the beginning. The 2nd recording on DG (and Stockhausen Edition) I like much more because it starts in a different section - very dramatic and rhythmic. Who was it that said that the most important parts are the beginning and endings? Definitely has a point. In any case, this piece really opened up for me after analysing it and after getting used to the "noises". Each Moment section is like a gem with a puzzle inside.
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!
