The Russian technique of piano playing is a specific school of thought and methodology developed by Russian pedagogues and musicians, such as Henry Ellenberg, Neuhaus, and Yudina, which has been taught in Russia and Eastern Europe for over a century. The technique is marked by its strong physical and physiological basis, with a special emphasis on tone production through the use of finger action, arm weight, and wrist motion. The goal is to develop a sense of naturalness, freedom, and relaxation in playing that will eventually lead to the greatest possible expressive effect.
