Pitch Class

An algorithm is proposed for performing harmonic analysis of tonal music. The algorithm begins with a representation of a piece as pitches and durations; it generates a representation in which the piece is divided into segments labeled with roots. This is a project of psychological interest, because much evidence exists that harmonic analysis is performed by trained and untrained listeners during listening; however, the perspective of the current project is computational rather than psychological, simply examining what has to be done computationally to produce "correct" analyses for pieces. One of the major innovations of the project is that pitches and chords are both represented on a spatial representation known as the "line of fifths"; this is similar to the circle of fifths except that distinctions are made between different spellings of the same pitch class. The algorithm uses preference rules to evaluate different possible interpretations, selecting the interpretation that most satisfies the preference rules. The algorithm has been computationally implemented; examples of the program's output are given and discussed.

Oral Transmission

In this commentary, I would like to add a few of our own, still unpublished, empirical observations concerning the possible role of absolute pitch memory (APM) in the oral transmission of folksongs. This empirical data poses some questions on the likelihood of the observed inter-recording tonic pitch consistency of Olthof, Janssen & Honing (2015) and how these could come about. Based on simulations of absolute pitch class of tonics during oral transmission of folk songs, I argue that the interplay of melodic range and vocal range might actually be the main reason for the observed non-uniformity, in contrast to the conclusions presented in Olthof et al. (2015). However, this does not invalidate the therein presented evidence, but makes the case more puzzling, consequently calling for more empirical research on the interaction of melodic and vocal range and latent APM as well as for more detailed modeling of oral transmission of folk songs.

The Way

This paper explores two new paradoxical sound patterns. The tones used to produce these patterns consist of six octave-related harmonics, whose amplitudes are scaled by a bell-shaped spectral envelope; these tones are clearly defined in terms of pitch class (C, C#, D, and so on) but are poorly defined in term s of height. One pattern consists of two tones that are separated by a half-octave. It is heard as ascending when played in one key, yet as descending when played in a different key. Further, when the pattern is played in any one key it is heard as ascending by some listeners but as descending by others (the tritone paradox). Another pattern that consists of simultaneous pairs of tones displays related properties (the semitone paradox). It is shown that the way the tritone paradox is perceived correlates with the speech characteristics of the listener, including his or her linguistic dialect. The findings suggest that the same, culturally acquired representation of pitch classes influences both speech production and also perception of this musical pattern.
