The Serenade for Winds in E-flat major K. 375, was written by Wolfgang Amadeus Mozart, on 15 October, 1781, for St Theresa's day. The original version of the serenade is scored for two clarinets, two horns, and two bassoons. Mozart later revised the score to add parts for two oboes. It is a work in five movements, and a complete performance lasts around 25 minutes.
