Essentials of Touch
ossip gabrilowitsch
"Modern pianoforte teachers in many instances seem to make deliberate attempts to complicate the very simple matter of touch. In the final analyses the whole study of touch may be resolved into two means of administering force to the keyboard, i. e., weight and muscular activity. The amount of pressure brought to bear upon the keys depends upon the amount of arm weight and upon the quickness with which the muscles of the hand, forearm, full-arm and back permit the key to be struck. Upon these two means of administering force must depend whatever differentiation in dynamic power and tonal quality the player desires to produce. The various gradations of tone which the virtuoso's hand and arm are trained to execute are so minute that it is impossible for me to conceive of a scientific instrument or scale to measure them. Physiologists have attempted to construct instruments to do this, but little of value has come from such experiments.
