ABSTRACT
The chord qualities (CDV), Tonal Dynamism Value (TDV), and Harmonic Progression Dynamism Value (HPDV) streams all indicate somewhat different shapes of tension and release, demonstrating the interactive complexity of the harmonic effect. Two additional points should be made here, the first being that the rate of harmonic change should be carefully noted so that a proper selection of pitches goes into assessing each chord and chord change. The second point has to do with which notes are considered part of the prevailing harmony, a distinction that can be difficult to determine in cases where the details of the style are not known. The Western approach to harmony seen in the Wagner is focused more on extensive development of established or implied chord progressions, including possible shifting of the tonal centre, often temporarily. The prevalence of diatonic, modal, and chromatic chords and progressions in global harmonic practices that flow out of 12-EDO conceptions poses particular challenges for the analytical method.
