I was watching a tutorial on how this guy finds scales to play on top of jazz chords. And I was wondering if this a good method to use, and if not how do I know which scales to improvise on chords. Do I use a table, or is this technique sound?
In this "whole-step" technique the chord tones are shown in bold. The notes that we figure out (the ones that are not bold) are a whole step away from each chord tone. The notes then make up a certain scale we can improvise on.
Cmaj7: C E G B
C D E F# G A B
These notes make up the scale: C Lydian
Cmin7: C Eb G Bb
C D Eb F G A Bb
C7: C E G Bb
C D E F# G A Bb
C Lydian Dominant
Which basically means that for every Major scale I use a Lydian, and for every Minor scale I use a Dorian, and for every Dominant Major chord I use a Lydian-Dominant.
