The authors describe a simple computational system for identifying hierarchical structure in melodies based on frequency proximity and temporal distance, and assuming categorical perception. The model is based to some extent on Tenney's 1961 book, Meta Hodos.

Terhardt, E. "Pitch, Consonance, and Harmony." J. Acous. Soc. Am. 55(5) (1974): 1061--1069.

Stumpf used the listener's judgment of the harmonic interval's "fusion" as the ranking criterion for his perception study; Malmberg used "smoothness" for his. The discrepancies between their studies are a result of the uncontrolled overtone series used in tone production, and the bias due to the adjective used to describe the harmonic intervals. Psychoacoustic studies relating to harmonic intervals continued in the first half of the twentieth century. Reviews of their contributions can be found in this article.

Terhardt, E. "Toward Understanding Pitch Perception: Problems, Concepts and Solutions." In Psychophysical, Physiological and Behavioural Studies in Hearing, edited by G. van den Brink and F. A. Bilsen. Delft University Press, 1980.

Terhardt presents a broad overview of pitch perception concepts and terminology.

Terhardt, E. "Pitch of Pure of Tones: Its Relation to Intensity." In Facts and Models in Hearing, edited by E. Zwicker and E. Terhardt. New York: Springer-Verlag, 1974.

The author finds that for some individuals the change in pitch with intensity can be as large as that reported by Stevens; however, when these changes are averaged over many subjects, the changes are insignificant.

Terhardt, E. "Gestalt Principles and Music Perception." In Auditory Processing of Complex Sounds, edited by W. A. Yost and C. S. Watson. Hillsdale, NJ: Lawrence Erlbaum, 1987.

Terhardt identifies contours and categorized representations of sensory objects as the focus of gestalt perception. The theory presented is known as Hierarchical Processing of Categories (HPC) in which perception is organized on hierarchical layers, each of which are concerned only with categorizing or recategorizing. The most peripheral level corresponds to analytic listening and spectral pitch, analogous to primary visual contours, whereas synthetic forms are secondary, including virtual pitch. The multiple levels of perception associated with Western Tonal music are considered within the context of HPC.

Terwoght, M. M., and F. van Grinsven. "Musical Expression of Moodstates." Psych. Music 19 (1991): 99--109.

The authors present an experimental study of emotional response to short extracts from eight pieces of classical music.

Treisman, A. "Properties, Parts, and Objects." In Handbook of Perception and Human Performance, edited by K. R. Boff, L. Kaufman, and J. P. Thomas, Chap. 35. New York: Wiley, 1986.

Treisman explores the information-processing mechanisms that identify the objects and events of subjective experience from physical stimuli. Includes coverage of similarity judgment, perceptual analysis of dimensions/features/parts, and integration of parts and properties. Although most of the coverage and examples are based on visual studies, auditory studies are covered where appropriate.

Truax, B. Acoustic Communication. Norwood, NJ: Ablex, 1984.

Broad coverage of sound including speech, music, natural sound and sounds of modern life. Truax presents a communication model that places sound in a mediating role between listeners and the environment. He presents results of the World Soundscape Project.

Tzelgov, J., R. Srebro, A. Henik, and A. Kushelevsky. "Radiation Detection by Ear and by Eye." Human Factors 29(1) (1987): 87--98.

Tzelgov et al. found that in a seach task the auditory signal was better than the visual display or the dual mode system. In a detection task, there were no differences between the single modes and no differences between single modes and dual mode. Their interpretation of the results considers a visual bias effect in which the operator's attention is directed away from other aspects of the monitoring task.
