Most difficult single movement of a Mozart sonata?

[glavigne]

What's the most difficult movement of a mozart sonata, outside the context of the other movements? Musically? Technically?

[49410enrique]

hmm i'd vote on technical and and musical basis (i.e. ensemble) i was approach by another student about preppping this with them in the summer, i had to say i'll think about it, i don't really 'fear'  any of the other piano sonatas, but this one makes me nervous just thinking about performing it.!

I am a Grade 10 piano student in the Royal Conservatory of Music, and I have played many piano sonatas by Mozart. I don't think any of his movements are extremely hard; he prefered elegance over virtuosity. But some notable movements her wrote were the 1st and 3rd movement of his K 331 (the second being Alla Turca).
