Jazz superimpositions is not a conventional music method book. It rather gathers together various harmonic tools that can be used with superimposition, substitution and reharmonisation techniques.
The main idea is to provide the reader with various devices in order to be able to superimpose/substitute them onto any original harmonic progression.
It has been written for any musician but especially for guitarists, in both the English and French languages.

The book includes the following sections:How to use the bookThe harmonic tools, organised by :TriadsShell voicingsArpeggiosPentatonicsBop scalesSymmetrical scales (Messiaen Modes)Hexatonics (triad pairs)Some of N. Slonimsky's "thesaurus" patterns applied to superimposition.
Each one of the harmonic tools in the above-mentioned list is described with:Standard notationA circle of fifth diagramFingerings for guitar playersA superimposition table
The superimposition table is the core of the book. It provides quick access to the melodic scale, which is superimposed every half step from the root to the major seventh. The intervals created are given and the types of chords on which the superimposition can be played are suggested.
