Title: Generalizing the Orbifold Model for Voice Leading
Abstract: In music theory, “voice leading” is a technical term referring to the
assignment of parts (voices or instruments) to notes to create harmonies
(chords) that change over time. Previous work in mathematical music
theory has modeled chords as points in orbifolds constructed according
to equivalences commonly encountered in music (e.g., octave
equivalence). In these models, voice leading corresponds to paths in
the orbifolds. In this talk, I will discuss an approach to generalizing
these models to incorporate loudness. This approach allows for the
modeling of resting (absence) and re-entry of individual voices, an
aspect of voice leading that is ubiquitous across musical genres.
