“Linguistic and musical sound systems illustrate a common theme in the study of music-language relations. On the surface, the two domains are dramatically different. Music uses pitch in ways that speech does not, and speech organizes timbre to a degree seldom seen in music. Yet beneath these differences lie deep connections in terms of cognitive and neural processing. Most notably, in both domains the mind interacts with one particular aspect of sound (pitch in music, and timbre in speech) to create a perceptually discretized system. Importantly, this perceptual discretization is not an automatic byproduct of human auditory perception. For example, linguistic and musical sequences present the ear with continuous variations in amplitude, yet loudness is not perceived in terms of discrete categories. Instead, the perceptual discretization of musical pitch and linguistic timbre reflects the activity of a powerful cognitive system, built to separate within-category sonic variation from differences that indicate a change in sound category. Although music and speech differ in the primary acoustic feature used for sound category formation, it appears that the mechanisms that create and maintain learned sound categories in the two domains may have a substantial degree of overlap. Such overlap has implications for both practical and theoretical issues surrounding human communicative development.

In the 20th century, relations between spoken and musical sound systems were largely explored by artists. For example, the boundary between the domains played an important role in innovative works such as Schoenberg's Pierrot Lunaire and Reich's Different Trains (cf. Risset, 1991). In the 21st century, science is finally beginning to catch up, as relations between spoken and musical sound systems prove themselves to be a fruitful domain for research in cognitive neuroscience. Such work has already begun to yield new insights into our species' uniquely powerful communicative abilities.”
