Hear pieces from a variety of composers at the Seattle Chamber Music Society's annual six-day winter program. This year's theme is centered on a celebration of Beethoven’s 250th birthday. The first weekend of the festival will feature half of Beethoven’s string quartets, performed by the Ehnes Quartet, with each of the first three concerts featuring one work from the three eras of his life and career as a composer. The second weekend will feature violin sonatas by Grieg and Mozart, piano trios by Schubert and Ravel, and both of Brahms’ string quintets, along with concluding concerti by Johann Sebastian Bach.
