| Abstract | In the experiment we proof the paradoxical perception of
pitch. A tone sequence demonstrates this paradox: the sequence
is perceived as descending, although the first and last
tone are identical. The intransitivity of pitch perception generalizes
(Shepard 1964). It applies also to harmonic complex
tones with variate amplitude envelope and partials that
are arranged in intervals different from octaves. The paradox
perception in this experiment as well as in the Shepard scale
is modeled by a formula (spectrum of pitch differences) that
extends the virtual pitch algorithm (Terhardt 1998) to pitch
intervals.
