Revisiting Cadential Retention in GTTM
Masaki Matsubara, Takafumi Kodama, Satoshi Tojo · 2016
In GTTM, “Cadential Retention” grants the egg symbol to combine into one cadence (V-I). However, criteria for the cadential retention are ambiguous. In this paper, we propose a harmonic theory that the chord symbol has been limited on the basis of the musical scale, and formulate a cadence finding algorithm by adapting to the TPS theory. As a result, the candidate of the chord having a function of V is increased, it has facilitated cadence discovery. In addition, it can determine local cadence and the half cadence.
