Jorge was the eldest of three brothers. From an early age he demonstrated his leadership and talent as a composer and creator, writing his first piece at age fourteen. At 19 years old, into his beloved institution, the University of Chile, his qualities were felt immediately as an organizer, founding, along with Gustavo Becerra Alfonso Castagnetto and Sergio Canut de Bon, the magazine "Psalterium", to collect both the concerns of students of the National Conservatory, including concerns about the Chilean art world in general.
