Tritone Substitution Lines over a II V I
Here are some lines utilising a tritone substitution chord within a regular II V I chord progression. Usually a II V I chord progression (in this case in C major) would be this harmonic sequence: Dm7 – G7 – Cmaj7
In the case of these lines however, the G7 chord has been substituted with a Db7. This is the tritone substitution most commonly employed (over the dominant V7) in a II V I progression.
As the G7 and the Db7 chord both share a tritone interval between the notes F and B (Cb) the Db7 chord is considered a good substitution for the original G7 chord.
Here are the lines for you to learn and there is an attached audio file and PDF below for you too.
Practicing in all 12 keys
To help you practice these lines in other keys, I’m also attaching a backing track (played at 110 bpm) of a II V I played in all 12 keys using the tritone substitution on the V7 chord. There is also a PDF lead sheet for you to use whilst you practice the lines.
Enjoy the lines!
