A pianist
I have recently got back in to a rigorous practice schedule and have been experiencing fatigue. This is never pain but an inability to grab large cords or the missing of notes in fast passages that entail large stretches to retain legato. Normally once I reach this point I let my hands rest and for a few days and practice with a less vigorous motion of the metacarpal phalangeal joint. After resting, my hands come back stronger and more agile than the previous week. My right hand has actually grown in size (the left has begun to do the same but at a smaller rate, I believe to due to the fact that the passages for the left hand are usually less intricate than those for the right and each individual muscle has therefore had less training.) I can physically feel more muscle in the palm of my hand than I used to. I am very pleased with the approaches I have learned hear and do not feel that my pianistic abilities will be hampered in the future in regards to technical progress because of this. My question relating to this is that I want to continue with the progress I am making physically and do not want to do anything to hamper it. During the periods of fatigue before I warm up I always run my hand under hot water and massage the joints. I have also started to pop my knuckles when I do this as my hand seems more limber after. While I am sure the hot water is fine I am not so sure about the popping of the joints on a daily basis. I know every now and then is ok but as a part of my routine of warming up I am extremely skeptical. As a kid I was told to never pop my joints but not given a reason. Do you know what the possible implications of this, if any, could be. Thanks.
