Abstract

A device designed to demonstrate the phenomenon of "tone-mixing" will be exhibited and described. By means of this apparatus a vibrato may be synthetically produced with the number of pulses per second, extent of frequency fluctuation, and intensity relationship under control. The manner in which each of these variables influences the perceived tone can thus be determined. It is also possible to reproduce a vibrato whose rate, extent, and intensity relationship are identical with those of artistic singing. One factor at a time can then be varied and the relative importance of the several elements in the artistic tone determined. The device is also very convenient for demonstrating in the classroom the principle of sonance.
