I understood intersection in Xenakis sieve theory, as he explained himself here. But can anyone provide me a musical example from its production where he effectively used this?
Although I can't trace a thread between sieve theory and Xenakis's own compositions, a generalization of it (weighted sieves: set-theoretic operations defined as in fuzzy set theory) is used effectively by Sever Tipei's 1980's compositions using his (Sever's) MP1 software. An accessible composition and an accessible description(!) is Maiden Voyages.
