On the Colors of Vowels: Thinking through Synesthesia

Treatments of synesthesia in the arts and humanities generally assume a clear distinction between the neurological condition and the literary device. Synesthetes descriptions of colors seen in connection with music, for example, are thought to differ fundamentally from common expressions that rely on transpositions across sensory dimensions (bright vowels). This has not always been the case. The distinction emerged over the course of the twentieth century, as scientists sought to constitute synesthesia as a legitimate object of modern science.
On the Colors of Vowels investigates the ambiguity of visual descriptions of vowels across a wide range of disciplines, casting several landmark texts in a wholly new light. The book traces the migration of sound-color correspondence from its ancient host (music) to its modern one (vowels), investigating the vocalic Klangfarben of Hermann von Helmholtzs monumental Sensations of Tone, the vowel colors reported in early psychology surveys into audition colorée (colored hearing), the mis-matched timbres that form poetrys condition of possibility in Stéphane Mallarmés Crisis of Verse, and the vowel-color analogy central to both the universal alphabets of the nineteenth century and the phonological universals of the twentieth. The books final chapter turns to an intricately detailed account of vowel-color correspondence by Ferdinand de Saussure, suggesting how the linguists sensitivity to vowel coloration may have guided his groundbreaking study of Indo-European vocalism.
Bringing out the diverse ways in which visual conceptions of vowels have inflected the arts and sciences of modernity, On the Colors of Vowels makes it possible to see how discourses of the nineteenth and twentieth centuries crafted the enigma we now readily recognize as synesthesia.
