Advanced Tritone Substitution Tutorial
In this lesson we are going to look at various ways to add harmonic interest over dominant chords using tritones. Before watching this lesson, you should check out the introduction lesson on Tritone Substitution.
This lesson will give you a strong understanding of the concepts behind tritone substitution we also analyse specific applications in a few popular jazz standards.
The examples covered in this lesson are more advanced and also incorporate the theory from upper structure triads. If you are not comfortable with upper structures, it would be good to watch those lessons before diving into this one.
When you have a dominant chord, something I like to do is play a 13sus4 chord for the dominant chord and then play an upper structure triad over of the tritone of the original dominant.
This works well because the sus chord has an unresolved nature indicating it wants to move somewhere and that is exactly what happens — we move to an upper structure of the tritone which means we are still playing the same 3rd and 7th but with different colours on top from the extensions & alterations.
