As Marik said in one of his posts "There are three main aspects of piano playing (including ability to play “fast”).1) Music image.2) Mental and physical reaction.3) Physical comfort and relaxation."I am trying to analyse the physical aspect of this matter.Movements in piano practicing differ, sometimes considerably, from those in piano playing. In the first case we have to consider not only artistic purpose but physiological points as well.My point here is to try to find the basic or elementary motions that a piano student should learn from the beginning.The Mechanics of Piano Technique should tell us what kind of motions are applied to the following aspects of piano playing:1- The beginning and ending of passages.2- The production of isolated tones.3- Legato arpeggio passages.4- Scales and other legato single-note passages.5- Staccato passages of single notes.6- Staccato and legato chords.7- Staccato and legato double notes.8- Staccato and legato octaves.I'll be happy if some of you comment on this matter in accordance with their piano experience or their piano schooling.
Before that, though, I don't understand your statement, "Movements in piano practicing differ, sometimes considerably, from those in piano playing
When aiming for the most efficient piano practicing, I think that we have to take care that our proprioceptive sensations are clear and distinct. Slow playing serves this aim to some extent. While practicing, slight exaggerations of movements will provide more vivid proprioceptive material, which must be as if imprinted in the corresponding cells of our brain. The contours of this imprint have to be precise and distinct. I think that these sensations should be consciously perceived.
