Strata Harmony with Polychords in Seconds: Combining Persichetti and Schillinger Part 2

This is Part 2 in a two-part series on writing music with polychords, that is, stacked three-note chords in seconds as presented in the Vincent Persichetti book, and setting multi-layer chord continuities with a Schillinger System Strata Harmony approach. Use four trichord structures built from major and minor thirds, then stack these in two layers. Interpret polychord characteristics and properties in terms of the equivalent 3- to 6-element Pitch-Class Sets. Consider hexachord voicing and note doubling. Create chord continuities with polychords in seconds and apply strata harmony voice leading. The sketching process is demonstrated with five examples in different musical styles: woodwind trio chamber music, sectional harmony for saxophones or brass, string section background, and synthesizer texture.
