"The critics are occasionally pleased to compliment a pianist by saying that he plays in the grand style. Exactly what do they mean by that phrase? In the broadest sense, they mean a style of playing which penetrates deeper than the physical conquering of the piano. It concerns itself with the release of music. The “grand style” moved listeners through interpretation."
