Mid-Columbia Sinfonietta this weekend will be presenting a musical program called “America: A Musical Portrait” at the Wy’east Middle School Performing Arts Center in Odell. The centerpiece will be a concerto Sinfonietta conductor Mark Steighner wrote for the mountain dulcimer. Mountain dulcimer virtuoso Stephen Seifert says the folk instrument is based on simple concepts, but is full of possibilities that the concerto brings out. Also in the concert will include Aaron Copland’s Lincoln Portrait, featuring narration from the speeches and writings of Abraham Lincoln by Hood River Mayor Paul Blackburn on Friday and Oregon Congressman Greg Walden on Sunday, and music by Anton Dvorak and Mark O’Connor. Performances will be Friday evening at 7 p.m. and Sunday afternoon at 2 p.m., with suggested donation $10.
