By means of the Iowa Piano Camera, which gives an objective record of movement of the keys of the piano, and a vacuum tube volt-meter, which measures changes in intensity on the decibel scale, we are able to measure changes in the action, and intensity changes of the piano, that is, we are able to study the relation of the intensity changes of the piano to that of the action.
