Here is an animation on the third part of the Divertimento K.253 for 2 Oboes, 2 Horns and 2 Bassoons.
You can follow the plan of the work, and read the score which is synchronized with the music, but also listen to every instrument separately or make all the associations you want.
Downloading can be a little bit long because there are 6 recordings included in the animation.
