Abstract

Although pitch has been considered an important area of auditory research since the birth of modern acoustics in the 19th century, some of the most significant developments in our understanding of this phenomenon have occurred comparatively recently. In auditory physiology, researchers are now identifying cells in the brainstem and cortex that may be involved in the derivation of pitch. In auditory psychophysics, dramatic developments over the last several years have changed our understanding of temporal pitch mechanisms, and of the roles of resolved and unresolved harmonics. Computational modeling has provided new insights into the biological algorithms that may underlie pitch perception. Modern brain imaging techniques have suggested possible cortical locations for pitch mechanisms. This timely volume presents recent findings, while emphasizing their relation to the discoveries of the past. It brings together insights from several different methodological areas: physiology, psychophysics, comparative, imaging, etc., in addressing a single scientific problem. Pitch perception can be regarded as one of the main problems of hearing, and the multidisciplinary approach of the book provides a valuable reference source for graduate students and academics.

Abstract

Tuning, Timbre, Spectrum, Scale focuses on perceptions ofconsonance and dissonance, and how these are dependent on timbre. This alsorelates to musical scale: certain timbres sound more consonant in some scalesthan others. Sensory consonance and the ability to measure it have importantimplications for the design of audio devices and for musical theory andanalysis. Applications include methods of adapting sounds for arbitrary scales,ways to specify scales for nonharmonic sounds, and techniques of soundmanipulation based on maximizing (or minimizing) consonance. Specialconsideration is given here to a new method of adaptive tuning that canautomatically adjust the tuning of a piece based its timbral character so as tominimize dissonance. Audio examples illustrating the ideas presented areprovided for free on the Springer Extras website (http://extras.springer.com). Thisunique analysis of sound and scale will be of interest to physicists andengineers working in acoustics, as well as to musicians and psychologists .
