The book is from basically the “experimental music” school of electronic music. The idea was/is that music will be completely transmuted by electronics and computers, leaving traditional music behind. Here “traditional music” means almost everything people actually listen to, from orchestras to GarageBand electronica to pop.

The claim may be a bit aspirational right now, but in theory “electronic music” subsumes all music. Or enlarges music so much that traditional musical ideas are special cases, not necessarily relevant.

I’m trying to pitch this properly as a very cool concept. But I no longer believe it will happen in my lifetime.
