Exploring Reharmonisation: Examples Tritone Substitution in Work

An earlier post looked at Mark Levine's jazz reharmonisation book where he talked about tritone substitution.

The following sound except is from the jazz standard tune "Autumn Leaves".  Again, a very brief snippet due to the early stages of the project [at least when it was recorded], it shows the original chord sequence followed by a sequence where elements of tritone substitution have been implemented.

[This tritone substitution technique proved to be vital to the rest of the project.  Tritone substitution and the creating of reharmonised ii-V sequences became one of the central foundations to every major reharmonisation produced.  This early recording and the subsequent study that followed it was perhaps the most important step in the ruleset's maturity and in the project's practical development.]
