The Underpinnings of Polychordal Dissonance and Consonance. Written by Andrew Hanna
In last article, Polychords and Jazz Improviser, it was discussed how one can learn and apply polychords to an improvisation. Continuing with last article, understanding of polychordal consonance and dissonance will be explored. As many music students may remember from their studies of basic tertian harmony, common pattern for harmonic movement follows following formula: IV-V7-I. A simple analysis of this formula would conclude that IV chord announces dominant chord, which in this case produces tension, and this tension is then resolve to I chord. As this analysis has shown, polychords and other harmonic concepts operate under similar rules. Within this article, there will be two opposing viewpoints presented concerning polychordal dissonance/consonance.
Throughout this discussion of polychordal dissonance and consonance, use of triads will be used in all examples. The use of triads in this discussion makes it easier for novice student to grasp polychordal dissonance/consonance. When one begins to apply this idea to tertian harmony that is larger in scope than triads (i.e. seventh chords and larger), larger harmonies tend to function differently regarding dissonance and consonance. For this discussion of polychordal dissonance/consonance to continue, one needs to draw a circle of fourths where "C" is would be at twelve o’clock and "F#" is at 6 o’clock. After completing this circle, one then needs to number tonal centers, starting with "C" in a clockwise fashion. For example: C is I, G is II, D is III, and continue to number in like fashion.
One of pioneering principles that Vincent Persichetti set forth in his Twenty-Century Harmony, was that if one were to continue around circle, as described above, polychords will become more dissonant. In contrast to Persichetti’s principle of polychordal dissonance, another view on polychordal dissonance is that if one were to maintain above mentioned circle of fifths, but unlike previous example, one needs to renumber chordal units. If one were to start will C and label it "I" and continue this process clockwise until they stopped at F#, one then should have labeled F# as "VII." If one were to start at "C" again and continue labeling chordal units in a counter-clockwise fashion, one should end with an identical numerical pattern as previously described.
