Sinfonia Concertante in E-flat major for violin, viola and orchestra, K. 364 (selections)

The sinfonia concertante — half concerto, half symphony — sets multiple soloists against the orchestra, and Mozart's E-flat major work of 1779, written in Salzburg, is the genre's acknowledged masterwork. Violin and viola trade phrases like two operatic characters, and Mozart asks the viola to tune its strings up a semitone for extra brilliance. The C minor Andante is among his most profound slow movements. This concert presents selections from the work.
