Washington Square Music Festival

This popular summer series opens its 56th season with a quirky item: Villa-Lobos's Concerto for Harmonica and Orchestra. (The solo part will be played by Robert Bonfiglio.) Other works include Debussy's Reverie (arranged for harmonica and ensemble) and the adagietto from Mahler's Fifth Symphony, for strings and harp (but no harmonica). On June 24, the series continues with a vocal-music program, which includes pieces by Scarlatti, Chailley, Cherubini, Poulenc and others.
