Just look at Alicia De Larrocha
Exceptionally small (just 4.8 feet) her hands are very small
She plays just everything from the literature including Frank, Rachmaninov, Granados and play them beutifully no matter if she has to use broken chords
Another pianist here in pianostreet (Robert Henry) reaches a 9ninth and has rather small hands. He playes everything from the piano repertory too nothing excluded
