The Music Theory Online Dissertation Listing of Modulo-Seven Transformations in Post-Functional Music
Quick Navigation of this Document:
Many musical compositions from the end of the nineteenth century and the beginning of
the twentieth century retain some elements of functional tonality but abandon others. Most
analytical methods are designed to address either tonal music or atonal music, but no single
method completely illuminates this body of extended-tonal music. While both tonal and
post-tonal theory have been extended in various ways to address this music, the use of tonal
theory for analysis of this repertoire has not been completely formalized. The main obstacle
for prolongational views of extended tonality is finding sufficient conditions for establishing
that certain harmonies are structural in the absence of traditional harmonic function. In
this regard, acoustical measures of stability, motivic connections, and chord equivalence
all may form a part in determining the structural harmonies. Prolongational analyses of
music may be represented by Schenkerian notation or transformational networks based on
Lewin's Generalized Musical Intervals and Transformations (1987). This study explores a
number of specific graphing techniques, including the diatonic lattice (Jones 2002), the just-
intonation Tonnetz, and mod-12/mod-7 prolongational networks. After using group theory
to explore the relationship of diatonic scale theory and tuning theory to transformational and
prolongational analysis, excerpts from Wolf, Wagner, and Ravel are analyzed using mod-7
transformations. In giving support for prolongational analyses of chromatic and neo-tonal
music, this study provides a case for tonality-based approaches to post-functional harmony.
