As one might expect from its name, the Mozart Sinfonia concertante in E-flat, K. 364 is both symphonic in character and has a violin and viola soloists, in the manner of a double concerto. However, concertante also meant to play “in concert” among a mixed group of instruments, and Mozart writes in this more conversational vein as well.
Each of the winds has a distinctive voice in addition to the two soloists, sometimes playing along with them colla parte and other times interjecting their own phrases. Mozart’s writing in this symphonic concerto was inspired by his travels, first to Munich and Mannheim in 1777, then on to Paris in 1778.
Here are Isabelle Faust and Antoine Tamestit in this lovely work:
