Die Lehre von der Tonempfindungen als physiologische Grundlage für die Theorie der Musik.

Helmholtz’s theory of hearing, upon which all modern theories of resonance are based. This exhaustive study of acoustics ranks as one of the greatest books on the subject and shows that Helmholtz was, besides being a great physicist and physician, an accomplished musician.
