Pianist Henrik Kilhamn analyzes Mozart's Sonata "Facile" in C major KV.545, 1st movement: Allegro. We find all the usual Mozart elements of phrase efficiancy, scales and amazing sequences, and although Mozart said it was "for beginners" it's never easy to pull off his gestures as smooth and free of friction as you would want them. It's also a good piece to understand the core building blocks of sonata form, because it's almost prototypical for the purpose (albeit with a significant individual variation). 

Apologies for the audio quality in the beginning and end - there was a technical mishap that I discovered too late so I had to use an inferior audio quality source.
