Babbling brooks, birdsong, wind—the earth’s aural marvels have been the subject of musical compositions across time and cultures. For instance, Beethoven’s Symphony No. 6, Pastoral, reflects the sights and sounds of the rural areas that the composer would visit. It is one of three pieces that will be performed on Earth Day by the Sonoma State University (SSU) Symphony Orchestra in its Songs of the Earth concert. In addition to Beethoven’s work, the symphony will also perform Lyadov’s Eight Russian Folk Songs as well as Moritûra Terra (Latin for “Dying Earth”), the winning entry of the SSU Composition Contest. The concert will be held on April 22 at 7:30 p.m. in Weill Hall at SSU’s Green Music Center in Rohnert Park. Tickets are $8; free for SSU students. See sonoma.edu/music for more information.
