Chamber Music Society of Oregon
    The award-winning Oregon Sinfonietta, now in its 44th season and conducted by Dr. Donald L. Appert, is a full symphony orchestra of about sixty musicians that draws together community musicians from the greater Portland, Oregon and Vancouver, Washington metropolitan area. The orchestra performs four free concerts per season at the Sunnyside Seventh-day Adventist Church in SE Portland. The exciting repertoire for the 2016 – 2017 season includes Mozart's Violin Concerto No. 5, overtures by Brahms and Wagner, Beethoven's Eroica symphony, Shostakovich's Symphony No. 9, and Tchaikovsky's Pathιtique symphony, along with other great works. Talented winners of the CMSO Concerto Competition also perform full concertos with the orchestra each season.
    The Oregon Sinfonietta is seeking more string players, particularly cello and bass, to join us in performing the great works of the classical music repertoire. No audition is necessary. Rehearsals are held on Thursday nights, 7:00 p.m. to 9:30 p.m., at Concordia University, Portland, Oregon, in the Fine Arts Building on NE 27th Avenue, between NE Holman and NE Dekum streets. (Please see the below maps and directions to Concordia University.) For more information, please call (503) 285-7621, or e-mail Dr. Appert at
