i mean, i don't want an ABRSM grade...hehehe... but to what standard pieces do you compare it?
Not that tricky. I suppose if you can play most of the Beethoven middle-period sonatas without busting your guts you shouldn't have too much trouble with it.
have you heard his cipressi op. 17 or alt wien op. 30?Hamelin is playing them at this year's Husum festival...
