"REGARDS ON TWO REGARDS BY MESSIAEN: Post-Tonal Music Segmentation
Using Pitch Context Distances in the Spiral Array"
by Elaine Chew (echew@usc.edu)

ABSTRACT: This paper describes an O(n) algorithm for segmenting music
automatically by pitch context using the Spiral Array, a mathematical
model for tonality, and applies it to the segmentation of post-tonal
music, namely, Olivier Messiaen's Regards IV and XVI from his Vingt
Regards sur l'Enfant Jesus.  Using the idea of the center of effect
(c.e.), a summary point in the interior of the Spiral Array,
segmentation boundaries map to peaks in the distance between the
c.e.'s of adjacent segments of music.  The best-case computed
boundaries are, on average, within 0.94% (for Regard IV) and 0.11%
(for Regard XVI) of their targets.
