Extended Perf. Breakdown 3 - One of the ways I access interesting sounds is to use substitutions. I think of a layering of sounds, more complex harmony played on top of the basic harmony (the four note arpeggios of all of the five chord types I mentioned in an earlier video bank). Major arpeggios (both ionian and lydian) are easy sounds and shapes to use as substitutions, and they assume a very different identity when placed in a new context. Using the relative major (ionian) over a minor chord will produce a minor 9th, and lydian major over the relative minor creates a minor 6/9 (for example, G ionian and lydian over E dorian minor), for the aeolian minor, use the flat 6 major, ionian and lydian (C ionian and lydian over E aeolian minor), for the phrygian minor, the flat 2 major ionian and lydian (F ionian and lydian over E phrygian minor), for the locrian, the flat 5 major, ionian and lydian (B flat ionian and lydian over E locrian half diminished). If a tune has an open section in which it's possible to treat the harmony freely, I'll often combine all of the major substitutions over a minor chord, for example G,C, F and B flat major over E minor. Gradually the application of the theory leads to the ability to visualize and execute shapes and internalize sounds. The ultimate goal is to have the harmony internalized to the point that your ear is well attuned to all of the the nuances of the various chords and their extensions. Along with this knowledge and your confidence to apply it in your improvising and composing, you will be better able to identify and respond sympathetically to your bandmates.
