One of the greatest qualities of the blues is the fact that so much can be expressed with just one simple scale - the Minor Pentatonic Scale. But if you are like me, you are always looking for new forms of expression on the guitar.
Let’s consider Minor Blues. You may be familiar with the standard 12 bar blues chord progression. In this guitar lesson, we will consider the Minor Blues chord progression. One of the most common Minor Blues keys is D Minor. The D Minor Blues 12 bar blues progression is
| Dm7 | Dm7 | Dm7 | Dm7 | Gm7 | Gm7 |
| Dm7 | Dm7 | A7 | A7 | Dm7 | Dm7 |
Now, one could very well solo over these chords strictly with the D Minor Pentatonic Scale. But unless you want to sound like thousands of other blues players, you can readily expand your horizons.
Let’s consider the 3 chords in the above progression. Over the Dm7, you can clearly solo using the D Minor Pentatonic Scale. When it comes time for the change to Gm7, you will find that the G Dorian Scale allows you further freedom of expression than otherwise possible with the plain old D Minor Pentatonic Scale.
Now let’s consider the A Dom7 chord. You can solo over this chord using D Pentatonic Minor, but if you want a greater degree of musical exploration, then experiment with the A Mixolydian b6 scale.
There is some theory behind why this scale makes sense. I won’t get into the theory because I really want you to use your ears. But suffice it to say that in Minor keys, the plain old Mixolydian Scale isn’t as effective as a modified Mixolydian Scale. The Mixolydian b6 Scale comes about when analyzing the Jazz Melodic Minor modes. But don’t worry about that - just experiment with the the scale and see how it sounds over the Dom7 chord of a Minor Blues progression.
Below is some tab showing the 3 scales that I have mentioned: D Minor Pentatonic, G Dorian and A Mixolydian b6.

One benefit of the above scale shapes is that they are all played at the 12th fret position. Of course, I always recommend using the entire fretboard and avoiding so-called boxes, but the above shapes definitely give you a starting point from which to launch your creativity.
I recommend you record the D Minor Blues chord progression and experiment with these scales. In the end, I think you will have discovered some new forms of expression in a musical genre that all too often is characterized by cliche playing.
Later,
Brian
