A couple weeks ago I used a "falling leaves" analogy to describe Klavierstuck XI. In this work, actual leaves are used as "found sound objects" to make musical noise. In a barn. With a homemade shower stall. Hilarity ensures.
HERBSTMUSIK HERBSTMUSIK is a theatrical piece portraying a "scene from daily life". Richard Toop describes (in his article "Stockhausen's Secret Theatre - Unfinished Projects..."), sketches for a 1969 work called OPER (Opera), where some scenes consist of "abstract" activities which create musical sounds, and some other scenes consist of more typical "daily life" activities, but which emphasize the "ambient" noises of these scenarios (or add musical signals). HERBSTMUSIK, written a few years later, is kind of a combination of these two ideas, and portrays typical rural activities in a barn (or at least what I assume to be typical, having never played in a barn myself), set to various regular and irregular rhythms. The activities (hammering, breaking wood branches, threshing straw, rolling around in a pile of leaves, etc...) are organized so that the sounds of their stage actions are "musical". These were designed to create a kind "autumnal sound environment", and were probably informed by Stockhausen's own nostalgia for earlier times.
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!
