Sonoma Bach is a non-profit arts organization based in Sonoma County, California. Founded in 1991 as a resident organization at Sonoma State University, we became fully independent on July 1, 2010. Sonoma Bach sponsors several early music ensembles, presents an exciting concert series, offers classes and workshops, produces the Choir Loft radio show, and much, much more. We invite you to explore and see what we're up to!
