Festival faculty and fellows share the stage in this program featuring works that intermingle wind and string instruments. Amy Beach’s brilliant Theme and Variations is an early 20th-century Romantic treasure from the first American woman to publish a symphony. Jean Françaix’s superbly crafted music is bracingly witty and always entertaining. His Dixtuor for 10 players brings together the rarely seen combination of wind and string quintets. Beethoven’s Septet was an immediate success at its premiere in 1800 and quickly became one of his most popular works. This luminous piece is scored for a mixed ensemble with a notably challenging violin part, taken on in this performance by faculty violinist Martin Beaver.
