This lesson is the third part of the serie "Jazz Guitar Lines Over Common Chord Changes" that provides easy jazz guitar licks for beginners to play over II V, II V I and I IV II V progressions. These lines are majoritarily built with the major blues scale, the Mixolydian mode and a whole-tone scale motif.
What Is Chord Substitution?
Chord substitution is to replace a chord by another one to add more harmonic interest to a piece, a song or a chord progression. In jazz music, this technique is widely used by composers and improvisers. It can be useful to reharmonize a chord sequence or a jazz standard.
This lesson will help you better understand what is the diatonic chord substitution.
