(no dust jacket) [a good sound copy, with a tiny white blemish on the front cover but otherwise just a bit of wear at the extremities; front hinge feels a little weak, but is not cracked or split; gilt spine lettering is bright and unrubbed; bookplate of one-time owner, MGM writer-producer Carey Wilson, on front pastedown, as well as the embossed "Library of Paul Bern" stamp on the ffep; NOTE that many leaves (pages) are uncut, also that this copy contains the original publisher's packing slip]. (figures, tables, musical examples, etc.) Musicological madness, an insanely deep-dish examination, very influential in its field, of how we humans hear music. Originally published in Germany in 1863, the publication history of the English-language editions is outlined in a bibliographical note: "First English Edition, June, 1875; Second Edition, revised and Appendix added, August, 1885; Third Edition, reprinted from Second Edition, June 1895; Fourth Edition [this one], reprinted from Third Edition, November, 1912." It's further stated on the title page that this edition has been "Translated, thoroughly Revised and Corrected, rendered conformable to the Four (and last) German Edition of 1877, with numerous additional Notes and a New additional Appendix bringing down information to 1885 and especially adapted to the use of Musical Students." The original author, Herr Helmholtz, per Wikipedia, was "a German physician and physicist who made significant contributions in several scientific fields. In physiology and psychology, he is known for his mathematics of the eye, theories of vision, ideas on the visual perception of space, color vision research, and on the sensation of tone, perception of sound, and empiricism in the physiology of perception." (And he invented the ophthalmoscope, which "revolutionized the field of ophthalmology.") Honestly, though, the only thing I can imagine that's more intense than this 575-page tome (including all appendixes and index) is the idea that somebody translated it all from German!
