Clark High School is home to a number of performing groups, including the orchestra, band, and choir.
There is a beginning orchestra, for any student wishing to learn to play a classical string instrument, and intermediate and advanced orchestras for more experienced players. More proficient musicians may opt to audition for the chamber orchestra, which challenges students with a considerably advanced repertoire.
Once Marching season ends the marching band divides into two bands for the winter and spring seasons: the symphonic band (for intermediate musicians) and the wind ensemble (for advanced musicians). A drumline performs during the winter season, and there is a jazz band which has performed at Disneyland and on KLVX's Inside Education.
The chorus consists of several different groups. These include: All-men, All-women, Jazz, Concert, Advanced, and Chamber choirs.
Clark's full orchestra (consisting of orchestra and band) performed at Carnegie Hall in New York in 2008 and 2012. In March 2015, Clark's chamber orchestra performed at an ASTA national competition at Abravanel Hall in Salt Lake City. They placed as national and grand champions.
