The Theory and Technique of Electronic Music
"This is a book about using electronic techniques to record, synthesize, process,
and analyze musical sounds, a practice which came into its modern form in the
years 1948-1952, but whose technological means and artistic uses have undergone
several revolutions since then. Nowadays most electronic music is made
using computers, and this book will focus exclusively on what used to be called
computer music", but which should really now be called electronic music using
a computer".
