Oregon Sinfonietta
    The Chamber Music Society of Oregon is a 501(c)(3) non-profit organization that is administered by a dedicated group of unpaid volunteers. As always, our only expenses are for practical matters, such as rooms for rehearsal and performance, sheet music and soloists. CMSO does not receive any government funding, relying instead on donations from individuals and general fundraising. For the first time in many years, CMSO is having to pay for rehearsal space, so donations are gratefully accepted and appreciated. Donations are tax-deductible to the extent permitted by law. To donate, please enclose the following form with your contribution and mail to the address below.
