[1.IV.6.2] The Physiology of Technique
We still lack even a rudimentary understanding of the bio-mechanical processes that underlie technique. It certainly originates in the brain, and is probably associated with how the nerves communicate with the muscles, especially the fast muscles. What are the biological changes that accompany technique, or when the fingers are “warmed up”? What is the mechanism of PPI (section II.15)? What muscles are most important for playing the piano: the flexors, interossi, or lumbricals? Research on this type of knowledge applicable to piano practice has been rarely conducted and there is no indication that this situation will improve anytime soon. However, there is little question that this type of research is needed if we are to understand the physiology of technique.
