I've been looking for some concrete descriptions of technique.Though I have yet to find someone that is able to really describe his or her technique in a very concrete, understandable way. Who can manage to put into wórds, what he or she does at the piano. What I have found are comments which include a more general approach, rather than a very detailed and concrete description.Which includes sensations felt in tiny muscles, arm pressure points, wrist twisting, elbow pressure, hand-figuration (flat fingers, curved fingers, semi-curved) weight on hand, "finger-hanging" (as if your fore-arms would hang on the tips of your fingers) etc etc etc.
