Trabuco Hills High School, a member of the Saddleback Valley Unified School District (SVUSD), is located in Mission Viejo, California. The instrumental music program boasts locally, regionally and nationally recognized competing units such as the Thundering Mustangs Marching Unit, Color Guard, Percussion Ensemble, Symphony Orchestra, Chamber Strings, Intermediate Orchestra, Wind Ensemble, Symphonic Band, Jazz Ensemble and Pep Band. In 2001, Trabuco Hills High School was recognized as one of the four schools in the state to receive the California Distinguished School of Fine Arts award.


For the 2018-2019 school year, the Trabuco Hills High School Instrumental Music Program will be the proud host to one of the largest Western Band Association (WBA) circuit show in Southern California. The date for this year's show will be the traditional week before the WBA Marching Band Championships in Fresno, California. The 26th Annual Tournament in the Hills (WBA) will be held on Saturday, November 10, 2018. This tournament is the LARGEST single-day fundraiser for the entire instrumental music program. Consequently, we require that EVERY PARENT involved in any aspect of the instrumental music program (band, guard, orchestra and jazz ensemble) to volunteer in one way or another!!! Additionally, we were selected by the Western Band Association (WBA) circuit for the third year to be the proud host of the 2018 WBA Long Beach City College Super Show (WBA) on Saturday, October 27, 2018. Lastly, we will be hosting our second S&E festival again this year. The 2019 Trabuco Hills High School Solo & Ensemble Festival (SCSBOA) will be held on Saturday, May 11, 2019. SAVE ALL THESE DATES!!!


Bingo, held every Thursday night in the THHS Multipurpose Room and run exclusively by the music boosters is, along with Tournament in the Hills, a MAJOR fundraiser. Volunteering or playing is a great way to help the program, meet other boosters, and have a lot of fun. Proceeds go into the general fund of the Boosters and benefit all students in the Instrumental Music Program. Check out our website at
