The twelve bar blues progression is something almost every guitarist learns on their journey to becoming a fully fledged guitarist; most guitar players stick with the standard four variations of the twelve bar progression but there's heaps of cool chords waiting to be discovered for the advancing guitarist.
Our first step is to quickly review the four basic twelve bar blues progressions.
All progressions will be presented in the key of G
Progression #1
G /// | G /// | G /// | G /// |
C /// | C /// | G /// | G /// |
D7 ///| D7/// | G /// | D7/// || G (last time)
Progression #2
G /// | G /// | G /// | G /// |
C /// | C /// | G /// | G /// |
D7 ///| C /// | G /// | D7/// || G (last time)
Progression #3
G /// | C /// | G /// | G /// |
C /// | C /// | G /// | G /// |
D7 ///| D7/// | G /// | D7/// || G (last time)
Progression #4
G /// | C /// | G /// | G /// |
C /// | C /// | G /// | G /// |
D7 ///| C /// | G /// | D7/// || G (last time)
Here is our first variation of the blues progression, notice how we have changed the basic chord texture from major to minor.
Progression #5
Gm /// | Gm /// | Gm /// | Gm /// |
Cm /// | Cm /// | Gm /// | Gm /// |
D#9 ///| D9 /// | Gm /// | D7+/// || Gm (last time)
Progression #6
Gm /// | Cm /// | Gm /// | Gm /// |
Cm /// | Cm /// | Gm /// | Gm /// |
D#9 ///| D9 /// | Gm /// | D7+/// || Gm (last time)
Another way we could play these progressions is to use dominant seventh chords in bars nine and ten, like this:
In progressions 7 & 8 I'm using the (-) sign for minor chords; that's a common musical shorthand way of writing minor chords.
Progression #7
G- /// | G- /// | G- /// | G- /// |
C- /// | C- /// | G- /// | G- /// |
D#7 ///| D7 /// | G- /// | D7+/// || G- (last time)
Progression #8
G- /// | C- /// | G- /// | G- /// |
C- /// | C- /// | G- /// | G- /// |
D#7 ///| D7 /// | G- /// | D7+/// || G- (last time)
The chord in bar twelve is a D dominant seventh chord with a sharpened fifth.
Soloist information:
* minor pentatonic scales will work for the minor chords
* mixo-lydian modes for the dominant seventh chords
* whole tone scale for the dominant seventh sharp five chord
Next we will create a variation of the standard blues progression by featuring dominant seventh chords.
Progression #9
G /// | C7 /// | G /// | G7 /// |
C7 /// | C7 /// | G7 /// | G7 /// |
D7 /// | C7 /// | G /// | D7/// || G (last time)
or
Progression #9
G7 /// | C7 /// | G7 /// | G7 /// |
C7 /// | C7 /// | G7 /// | G7 /// |
D7 /// | C7 /// | G /// | D7/// || G7 (last time)
Soloist information:
* mixo-lydian modes for the dominant seventh chords
In this next progression we will add additional musical tension with the diminished chord in bar six.
Progression #10
G7 /// | C7 /// | G7 /// | G7 /// |
C7 /// | C#dim /// | G/D /// | E7 /// |
A7 /// | D7 /// | G7 /C7/ | G7/D7/ || G9 (last time)
Soloist information:
* mixo-lydian modes for the dominant seventh and dominant ninth chords
* diminished scale for the diminished chord
Remember to transpose these progressions into the popular blues keys e.g., A, D & E.
