Abstract
The project herein described is an experimental attempt to con- struct visual aids for the study of voice. Its purposes are: (1) to ako possible the visual perception of pitch change on a vertical scale; (2) to isolate certain overtones of the fundamental frequency in the hope of deriving some assistance to the improvement of quality. The principle of operation is the psychological phenomenon of stroboscopy, the illusion of stationary, constant light, as a result of synchronized interrupted vision. The Vocascope is composed of four essential parts: (1) the scanning drugs, (2) the light source, (3) the amplifier, (4) the filter.
