Of all living pianists, to the best of my belief, Anton Rubinstein is the most infallible reader and transposer a prima vista. I have stood behind him, scarcely crediting the evidence of my own senses, whilst he has rendered a manuscript orchestral score, in sixteen parts, on the piano with all the freedom and apposite expression of a first-class pianist who should be playing a P.F. composition with which he was tolerably familiar.
