The Tumon Bay Youth Orchestra™ (TBYO) held its first rehearsal in September 2018 officially launching Guam’s newest community youth orchestra. The ensemble is open to all youth ages 25 and under. Current membership includes college students and gifted youth from Guam’s public, private, defense and home schools.
This past summer and early fall, youth leaders of the TBYO mentored younger beginner musicians in the TBYO Jr. camps. As a result, TBYO has established a second orchestra (TBYO 2026) composed of youth who are in their high school sophomore year or younger. The ensemble welcomes new members who have previously taken an introductory ensemble course (beginning band/orchestra) or are concurrently taking private music instruction - no auditions are required to join at this time.
In July 2024, the Tumon Bay Youth Orchestra will join the Guam Territorial Band - Official Band of Guam, USA (GTB) in representing Guam at the SUMMA CUM LAUDE MUSIC FESTIVAL in Vienna, Austria. Both TBYO and GTB represented Guam at the 2019 Australian International Music Festival in Sydney, Australia bringing back two GOLD Awards.
Prospective members must audition to join the orchestra. New members are welcome at any time, year round. The main goals for the TBYO is to provide a platform for youth musicians from various schools to build camaraderie through music. Repertoire for the ensemble is vast and includes the grand masterworks of centuries past to the latest movie or video game soundtracks. We aim to entertain audiences of all ages.
