The Sinfonia Concertante for Violin, Viola and Orchestra in E-flat major, K. 364 (320d), was written by Wolfgang Amadeus Mozart. At the time of its composition in 1779, Mozart was on a tour of Europe that included Mannheim and Paris. Mozart had been experimenting with the sinfonia concertante genre and this work can be considered his most successful realization in this cross-over genre between symphony and concerto. The average performance time of the three movements of this piece is half an hour.
