When you think of chamber music, your mind wanders back in time a little — or perhaps a lot. Chamber music has roots back in the 17th century or so, when it started as the precursor to modern living room shows, with music written for small groups of instruments that could fit within the confines of a palace chamber, drawing room or reception hall. Today, chamber musicians keep the energy of the tiny orchestra alive with performances in churches, private residences and smaller venues — and Voices of Changes fills an even smaller niche in the little world of chamber music. This local ensemble of first-rate musicians takes on contemporary classical compositions, including 20th century classics and pieces by still-living composers. At 7:30 p.m. Monday, Oct. 24, at the Caruth Auditorium at SMU’s Owens Arts Center, 6101 Bishop Blvd. In their “Nanguan Concert,” Voices of Change will combine traditional ensembles with Chinese instruments for a night that’s billed as eclectic, classical and very much alive. Tickets are $30 at voicesofchange.com.
