ProvenanceThis portion of Thomas Young’s work includes five black and white plates, as well as pages 105-150 of the accompanying text. This text is an excerpt from a letter that was originally published as part of Philosophical Transactions, the journal printed and released by the Royal Society of London (Wood). There is a brief mention of the work in Young’s obituary in the September 1829 issue ofThe Gentleman’s Magazine. In addition to his work with sound and light, Young began the first successful translation of the Rosetta Stone in 1814, deciphering first the Greek “enchorial part of the inscription” before beginning work on “the hieroglyphical part” (Wood 278). Though he is not given primary credit as the translator, these first successful forays into the translation aided the ensuing work on hieroglyphics.

Parts DescriptionPlates VI and VII of Thomas Young’s Outlines of Experiments and Inquiries Respecting Sound and Light.
Printing ContextThese plates appear as scientific illustrations for the various acoustic concepts that Thomas Young outlines in his text.
Associated EventsThe Quaker doctor and scientist Thomas Young had just finished his medical studies at Gottingen University and Cambridge at the time of this text’s publication. This period of study not only prepared him for his medical career, but also provided “the specialist training with the development of cultural and literary studies” that “his Quaker upbringing had tended to suppress” (Wood 43). At Gottingen, his final lectio was on the subject of the human voice, and his interests shifted from the topic of medicine to the field of physics. He writes to a friend at the end of his studies, “I . . . have of late been diverging a little into the physical and mathematical theory of sound in general. I fancy I have made some singular observations on vibrating strings, and I mean to pursue my experiments” (Wood 50). Interestingly, this preoccupation resulted in his most famous experiments: those proving the wave theory of light. He began his medical practice in London after his time at Cambridge, so we must assume that his Outlines of Experiments was completed and published during his course of study (Wood).

SubjectThis image depicts an octave as rendered differently by each temperament. Young particularly emphasizes circumference Y, which represents the system that Young found most effective: twelve-tone equal temperament.
ThemeHearing. Sound waves. Harmonics. Musical notes. Chord structure.
SignificanceWhile "harmonics" has a specific definition within the world of music (the overtones associated with specific notes), the term can also have a broader meaning: “By the term harmonics, we denote the science of the relations of sound, silence, and note, which science is otherwise called Music, Acoustics, or Phonics” (Harmonics). Harmonics in this sense was far from settled at the point in time when Young’s text was published. Various philosophers and scientists had proposed different systems of tuning, or “temperament,” to best utilize the aural spectrum. In various temperaments, notes in an octave are tuned at intervals different than the whole number ratios by which they are normally spaced. These temperaments would produce different “beats,” like the ones in 43 A-D, which would afford the musician a whole new set of acoustic possibilities (Barbour). Young’s text presents these different “systems of temperament” in plate VII. Young explains that “the whole circumference represents an octave,” and goes on to list the various theories of temperament depicted in the image. Most significant is circumference Y, which represents the system, twelve-tone equal temperament, that Young believes is most desirable. During the Romantic period, this temperament became the most prevalent as it gave Romantic composers a variety of choices that were far purer than those afforded by other temperaments.
Despite Young’s eagerness to depict sound with a certain consistency, plate VII reminds us that sound was still being manipulated and reinterpreted throughout the eighteenth century with a flexibility that might be surprising to musicians and scholars today. Though twelve-tone equal temperament emerged as the most common choice of Romantic composers, alternate systems had been proposed and used throughout the eighteenth century (Barbour). Here we see sound resist the strict classification of the eye; such resistance seems to comment on a need for visual primacy that could not easily incorporate the nuances and variations of the aural. The aural here resists visual depiction even as Young and others press towards a more comprehensive understanding of how sound may be visually depicted. The sheer proliferation of these illustrations points to what may be a fundamental uneasiness with the difficulties of recording what has traditionally been ineffable. In the century before sound recordings became possible, the eye aspired to reign over sound despite myriad obstacles.
