His work spans various genres, including orchestral, chamber, and vocal music, often characterized by a blend of traditional forms and avant-garde techniques. Notable works include "Sinfonia" (1968), a groundbreaking piece for orchestra and voices that integrates quotations from other composers, and "Sequenza" series, which consists of 14 solo pieces for different instruments, showcasing the virtuosity and expressive potential of each instrument.
