Allied Groups

In addition to our college performing ensembles, SRJC hosts several allied groups that are run through the Community Education program. These non-credit courses are designed for members of the community who are not actively seeking a degree. For current information about course offerings and instructions how to enroll, visit the Community Education website.

Santa Rosa Chamber Orchestra (formerly the Baroque Sinfonia of Sonoma County)

This small chamber orchestra of the approximate size and instrumentation of Haydn's day includes students and members of the community from many walks of life who perform for their own enjoyment and the entertainment of others. Established in November 1971, its principal purpose is the performance of lesser-known works of the Baroque, Rococo, early Classical, and Contemporary periods. Each performance features an outstanding soloist from Northern California. The Orchestra performs three sets of concerts each semester, and rehearses Monday evenings from 7:00 to 10:00 PM.

The Symphonic Chorus performs at least two concerts each year, is the on-stage chorus for the annual Redwood Empire Sing-Along Messiah, and performs regularly with the Santa Rosa Symphony and other professional instrumentalists. The choir rehearses Monday evenings from 7:00 to 10:00 PM.

North Bay Sinfonietta

The North Bay Sinfonietta was formed by Conductor Cynthia Weichel in January 2014. The impetus to form this ensemble came from the many former loyal members of the Santa Rosa Junior College Orchestra which Ms. Weichel conducted from 1999 to 2012. The 30 plus members include amateur, professional and student musicians from Sonoma County. The orchestra’s mission is to present innovative programming which will include a broad range of music from Baroque to Contemporary, from standard symphonic music to chamber works, including music from lesser-known composers. The orchestra will also feature outstanding guest soloists from the greater Bay Area, and offer solo opportunities for talented musicians within our community. The orchestra presents concerts in the community in October, December, March and May. Membership is open to string, woodwinds, brass, and percussion players. Participation in the course requires an audition with the Music Director/Conductor prior to registration.
