Electrified, tingling tendons: the best analogy I can find to that physical, clear, feeling of the nerve pathways in the arms.
The electricity begins in the upperarm and is felt as a gentle, loose string, an enduring lightning along both arms, reaching into the forearm. Sometimes, quite frequently, it continues into both the left and the right hand, and into the fingers. The fingertips stay calm though.
Whenever a piano performance was about to happen or an exam’s or job interview’s start was nearing, I felt this magnetic lightning. These days I know that when the tendons are beginning to whisper their electric tunes, it’s time for showing what you’ve got, finally. The tingling tendons are part of my inner compass.
