Geza Revesz offers a comprehensive view including an overview of his own extensive often revolutionary, research in both psychology and acoustics. The book is arranged in three parts. Part 1 addresses the physical and physiological bases of sound, hearing and tone. Part 2 deals with the psychology of sound, including the basic elements of musical tone, the theory of intervals, consonance and dissonance, the sense of pitch, and the relation between tone and color perception. Part 3 treats fundamental problems of the psychology of music, including musical talent, the development and inheritance of musical ability and more.
