In November 1781 Mozart, in a letter to his father, mentioned the composition of this Serenade: 'I wrote this music for St Theresa's Day [15 October] - for Frau von Hickl's sister, or rather the sister-in-law of Herr von Hickl, court painter. But the chief reason why I composed it was in order to let Herr von Strack, who goes there every day, hear something of my composition, so I wrote it rather carefully.'Instrumentation:2 horns, 2 oboes, 2 clarinets and 2 bassoonsKV 375
