Your arranging skills will be highly dependent on your ability to reharmonize and recognize alternate chord choices in any situation.
The tritone substitution is one of the more useful harmonic progressions in jazz. It often functions as a substitute for the V7 chord in a ii-V7-I progression. The tritone substition adds alot of harmonic interest and it sounds very smooth because the roots of the chords are moving by only a half step.
In this video lesson, I explain the basics of the tritone sub, and a simple example of how it could be used. As always, leave any comments or questions below the video player, and I’ll answer them as best I can.
