"In the present work an attempt will be made to connect the boundaries of two sciences, which, although drawn towards each other by many natural affinities, have hitherto remained practically distinct--I mean the boundaries of physical and physiological acoustics on the one side, and of musical science and esthetics on the other. I endeavor to collect and arrange such materials for the theory of the sensations of hearing as already existed. The First Part of the following investigation is essentially physical and physiological. It contains a general investigation of the phenomenon of harmonic upper partial tones. The Second Part treats of the disturbances produced by the simultaneous production of two tones, namely the combinational tones and beats. In these first two Parts of the book, no attention is paid to esthetic considerations. Natural phenomena obeying a blind necessity, are alone treated. The Third Part treats of the construction of musical scales and notes. Here we come at once upon esthetic ground, and the differences of national and individual tastes begin to appear"--Book.
