Terhardt, E. (1980). Toward understanding pitch perception: Problems, concepts, and solutions. In: Psychophysical, Physiological, and Behavioural Studies in Hearing (van den Brink, G., Bilsen, F.A., eds.), Delft UP, Delft, 353-360
In the first part, the paper presents conceptual aspects of understanding pitch perception: the relationship between signal parameters and pitch, the origin of tonal affinity, and absolute pitch memory. In the second part, quantitative evaluation of the pitch of complex signals is outlined.
