7. Shaking the Arm
*Czesław Sielużycki - “The pianist’s hand” p. 261 and 305-306, Polish Music Edition, Cracow, 1982
Of course I do not mean that one must merely “shake the shoulder” to play correctly. The truth is closer to the opposite: it is correct playing that brings the impression of shaking the arms when performing certain very well defined technical movements. At the most, this shaking can be gradually stimulated principally by practicing staccato exercises or by doing gymnastics away from the piano (cf. exercise n° 2).
