Orchestra 1 (Freshman Orchestra) is composed entirely of freshman. What has traditionally been a group of about 50-60 members has in recent years blossomed into a grand ensemble of close to 100 members. Mr. Rick England conducts the orchestra, which performs many concerts, ranging from a beautiful Winter Concert, to the nice spring Concert in the Park, to the Fall String Concert (which it is one of the six orchestras performing). The orchestra also performs yearly at Disneyland's Carnation Plaza and takes a trip to Long Beach where they perform at SCSBOA String Festival.
 

Orchestra 2 (String Orchestra) has in the past been the largest of the three groups, so large, in fact, that it's director, Mr. Tom Forbes, has had to split the group into two periods in order to accommodate the size of the orchestra room. In addition to their many concerts, the orchestra goes with Orchestra 3 on the annual 4-5 day tour to places such as San Diego and San Francisco. On the tour, the orchestra also teams up with Orchestra 3 to compete as the Arcadia High School String Orchestra, which perennially wins prestigious awards at the competitions.

To be a member of Orchestra 3 (Symphony Strings), the musicians must audition. The group performs a wide variety of music, from Dvorak and Mendelssohn to Andrew Lloyd Webber and John Williams. In this past year, the orchestra competed in the Heritage Festival at San Jose, CA, and won multiple awards, including Best Orchestra Program and Best Performance by an Orchestra. The ensemble often joins with brass, wind, and percussionists from the band to perform as the Arcadia High School Symphony Orchestra in many of the year's concerts. The orchestra is directed by both Mr. Rick England and Mr. Tom Forbes.
