Edgard Victor Achille Charles Varèse—a French composer who spent much of his career in the United States—is renowned for his groundbreaking approach to music. His works spanned the 20th Century and are known for emphasizing timbre and rhythm. Varèse's innovative use of electronic media earned him the moniker "Father of Electronic Music." Notable compositions include Amériques and Ionisation, which featured unconventional sounds and instruments. Varèse was influential on composers like Boulez, Cage, and Zappa. He founded the International Composers' Guild and envisioned global, multi-lingual choral symphonies. Varèse's exploration of sound as a spatial entity reshaped classical music's boundaries.
