I work with many students who are experiencing pain in the forearm who have been told to rest. I look at the student playing and 9 times out of 10 am able to pinpoint the injury to constantly never letting the keyboard support the arms. Many students hold their arms slightly above the piano as they play or simply constantly move the wrists in upward motions. Relaxation of the arms is a downward motion. The keys go down, gravity is down, release of tension is a down release. As students learn to
release the tension of the arms and allow the hands to rest on the keys when they are not playing, the
pain will go away. The body will naturally go back to its comfortable state.
