Féré, Travail et Plaisir, Chapter XII, "Action Physiologique des Sens Musicaux." "A practical treatise on harmony," Goblot remarks (Revue Philosophique, July, 1901, p. 61), "ought to tell us in what way such an interval, or such a succession of intervals, affects us. A theoretical treatise on harmony ought to tell us the explanation of these impressions. In a word, musical harmony is a psychological science." He adds that this science is very far from being constituted yet; we have hardly even obtained a glimpse of it.
