Create a chord progression that combines Pitch-Class Set (PCS) harmonies with a Riemannian Transformation (RT) triadic progression. The RT progression includes chromatic mediant pairs, the SLIDE transformation and the symmetric scale hexachordal triad pair. The PCS is based on the all-interval tetrachord 4-Z15 and its Z-related companion 4-Z29. The harmony uses various PCS properties such as the original, transposed and inverted form, common notes for different forms, voicings that focus on specific intervals or dissonance distribution. This technique is demonstrated with an example orchestral composition. There's a companion document with text, diagrams and score excerpts available in the webshop.
