The circumstances of the origin of Sinfonia concertante in Eb major (KV 297 b) are disputed; it was probably created in Paris in April 1778 for four famous solo instrumentalists of the Mannheim Court Chapel. In his arrangement, Werner Egk included and extended the concertante aspect: In 1981, a few weeks before his death, he arranged the work for two oboes, clarinets, horns, bassoons each and double-bass so that now a solo quartet is opposed to a tutti quartet. For wind ensembles, this piece is a valuable addition to their repertoire, for Mozart lovers it is a charming view from an unfamiliar perspective. Instrumentation: 8 wind instruments (2 oboes, 2 clarinets, 2 bassoons, 2 horns) and double bass KV 297b
