Mozart composed 5 divertimenti for 2 basset horns and basson between 1783 and 1785. They were published in 1803. In 1805 an unknown composer published a piano transcription, rearranging the movements of the 5 divertimenti into 6 sonatines. Most popular is no. 1 and you probably know it from your early piano lessons.
I used both the piano transcription and the original wood wind score for my organ transcription. The organ score is attached.
