Synopsis
Excerpt from Proceedings of the American Academy of Arts and Sciences, 1893, Vol. 27
We have thought it desirable to ascertain what results would be reached in different registers with interference beats, such as are present in actual dissonances. It was of course necessary to em ploy simple tones. Our method was a direct one, viz. To produce two such tones simultaneously, and to vary the pitch of one of these by known amounts, estimating by the ear when the sound became the harshest.
