Members of the Columbia Orchestra will present a free chamber music concert at 7:30 p.m. tomorrow at Christ Episcopal Church, 6800 Oakland Mills Road, in Columbia.

The program will feature a Beethoven sextet for horns and strings, string quartets by William Grant Still and Hugo Cole, and more.

The Classical Encounters String Quartet - Columbia Orchestra violinists Robin Strempek and Marlene Browne, violist Chris Gosper and cellist Carolyn Ginnever - will perform two rarely heard string quartets by Cole, a British composer and music critic.

Cole, who studied in Paris with noted composition professor Nadia Boulanger, wrote his first and second Miniature String Quartets as examples of tuneful 20th-century compositions.

Violinists Paul Li and Catherine Ann Kraft, violist David Zajic, and cellist Arthur Fleming will perform Danzas de Panama by Still, an African-American composer.

This string ensemble will be augmented by two horns, Jeff Girdler and Anne Ward, to perform Beethoven's Sextet in E-flat major for Horns and Strings.

The intimate chamber music will be in stark contrast to Beethoven's monumental Symphony No. 9 (Choral), to be performed April 5-6 by the full Columbia Orchestra along with the McDaniel College Concert Choir, the Masterworks Chorale of Carroll County and the Peabody Children's Chorus.
