Anyway, it s the music that I later called Ambient. I don t think I understand what that term stands for anymore - it seems to have swollen to accommodate some quite unexpected bedfellows - but I still use it to distinguish it from pieces of music that have fixed duration and rhythmically connected, locked together elements.
The pedigree of this piece includes Thursday Afternoon, Neroli (whose subtitle is Thinking Music IV) and LUX. Ive made a lot of thinking music, but most of it I ve kept for myself. Now I notice that people are using some of those earlier records in the way that I use them - as provocative spaces for thinking - so I feel more inclined to make them public.
Pieces like this have another name: they re GENERATIVE. By that I mean they make themselves. My job as a composer is to set in place a group of sounds and phrases, and then some rules which decide what happens to them. I then set the whole system playing and see what it does, adjusting the sounds and the phrases and the rules until I get something I m happy with. Because those rules are probabilistic (often taking the form perform operation x, y percent of the time) the piece unfolds differently every time it is activated. What you have here is a recording of one of those unfoldings. CD in case bound sleeve with 12 page booklet.
