Am I the only one who doesnt know any famous piano pieces by Haydn?

I want to find a something that you could call a 'crowd pleaser' or at least something interesting.

Do any of you play Haydn? I always play mozart and could do with a change!!

Unlikely

Too many to list, but Hob XVI/23 in F has all the right ingredients and is my personal favourite. But it is generally agreed that his last 6 sonatas are his finest

At least 3 of us ... probably many more

Nothing wrong with Mozart. You COULD play nothing else for the rest of your life and be very happy.

Also Hob. XVI/37 in D is reasonably well known - at least you stand a chance of recognizing it when you hear it.Brendel plays Hob XVI:37, 1st Movement, Allegro con brio I don't know if it is one of his last six, but it is in Vol. 2 of my 3 volume edition

Including me, for the moment.

I much prefer Mozart, Beethoven and Schubert piano sonatas. However, I am aware that variety is good for my musical education and although I prefer these three, Haydn still has some wonderful moments and, sometimes, what I can only describe as a sense of playfulness.

As for being happy for the rest of ones life with just Mozart, not so sure: You might want a little more variety . . . eventually . . . maybe. Or maybe not!
