From what I've heard, Josef Hoffman had very small hands and even had a specially manufactured piano with less wide keys. I think Pletnev and Ashkenazy also have quite small hands.
Not that i am famous, but i have got small hands. An uncomfortable 10th at best.Perhaps my hands are better suited to dislocating peoples thumbs in arm wrestling competitions.Thal
I have small hands myself (octave only) and am curious to know small-handed pianists who made it to the top. The only one I know is the late Alicia de Larrocha. Do you know any other famous pianist with known small hands?
