The Significance of Weight Playing
"In this method of playing, the fingers are virtually 'glued to the keys' in that they leave them the least possible distance in order to accomplish their essential aims. This results in no waste motion of any kind, no loss of power and consequently the greatest possible conservation of energy. In this manner of playing the arm is so relaxed that it would fall to the side if the keyboard were removed from beneath it. Since the hand and the arm are relaxed the back (top) of the hand is almost on a level with the forearm.
"The high angular stroke which characterized the playing of the Czerny epoch and which could hardly fail to cause tired muscles and unbearably stiff playing, is seen very little in these days. By means of it the student was taught to deliver a blow to the keyboard—a blow which permitted very little modification to the requirements of modern technic.
"In my experience as a pianist and as a teacher, I have observed that the weight touch allows the greatest possible opportunity for the proper application of those all-important divisions of technic without which piano playing is not only inartistic, but devoid of all interest. Weight playing permits nothing to interfere with discriminative phrasing, complicated rhythmical problems, the infinitely subtle variation of time for expressive purposes now classed under the head of agogics, all shades of dynamic gradation; in fact everything that falls in the domain of the artist pianist.
