On the Sensitiveness of the Ear to Pitch and Change of Pitch in Music
Alexander John Ellis · Proceedings of the Musical Association · 1876
The principal aim of the present paper is to bring before the Musical Association some results obtained last autumn from numerous and very careful experiments by Dr. W. Preyer, Professor of Physiology in the University of Jena, because those results are not accessible in an English form, and seem to have a very practical bearing upon tuning and singing. My subordinate purpose is to exhibit a method of representing pitch and intervals, which shall be more consonant to the habits of musicians than that adopted by Dr. Preyer for the statement of his results. For the idea of this method I am indebted to Mr. Bosanquet, though I have worked it out somewhat differently from him.
