Thank you all so much for this discussion and for reigniting my interest in this piece, and another facet to return to with the recording and score. I will most certainly be keen to read your book Jerry.
I love, too, your reference to the 'great sigh' at the end of the LICHT Superformula. I had not thought of it in that way until now, but it's a beautiful description and one that contributes wonderfully to the approach to LICHT I am taking in my own exploration of LICHT in my PhD studies.
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!
