Oops I forgot to read the 1st post. Well at your level, I recommend Beethoven's 9th or 10th sonatas. Both of these are very beautiful works. Also, I think Mozart's Sonata K.332 is a great choice. For Haydn, play the Hob.XVI 36 in c sharp minor, which is a very pretty work.Oh and afarmboysforte, how would you compare Haydn's Sonata Hob.XVI 52 to Beethoven's Sonata Op.2 no.3?
