Electromagnet Oscillator Excites Piano Strings
By Will Herzog

Today, if I were to try and imagine such an electrical piano, it would
start with a big pre-charged capacitor, the charge dependent upon the
desired force of the strike.  This capacitor would be connected by the
"piano key", via electronic methods such as SCRs and optics, to give
an impulse to the electromagnet, to suck that string hard, to duplicate
the force of the hammer.
