This document provides information about electronic music and chance music from the 20th century. It defines electronic music as music that uses tape recorders and other technology to experiment with sounds, with early innovators including Edgar Varese and Karlheinz Stockhausen. Chance music is defined as music where the sounds emanate from the environment and the combination of sounds cannot be duplicated, with John Cage pioneering the genre through works like 4'33". The document educates on the similarities and differences between the two styles through a Venn diagram and encourages students to think about electronic music today.
