In this tutorial we’ll have a look at the guitar scales, arpeggios and substitutions we can use to improvise over minor guitar chords, so we can make our guitar solos more interesting. Unless specified, we take a Dm chord as example. Here’s a roundup:
The 3 minor diatonic scales (Dorian, Phrygian, Aeolian) are the obvious choice for playing over minor chords. Which of the 3 scales you play depends on the harmonic setting and the function of the chords you are playing over.
The Dorian mode is played over II chords, like in a II V I chord progression.
We’ll take a 2 5 1 in C major as an example:
|Dm7 |G7 |Cmaj7 |% |
|II |V |I | |
Over the Dm7 we play the D Dorian scale:
| D Dorian | D E F G A B C |
| Over Dm7 | 1 9 b3 11 5 6 b7 |
Here’s the scale chart for D Dorian mode in its root position:
The Dorian scale is also used to play over minor chords in modal tunes, like So What.
|Cmaj7 Am7 |Dm7 G7 |Em7 A7 |Dm7 G7 |
|I VI |II V |III VI7 |II V |
On the Em7 in the 3rd bar we can play the E Phrygian mode. As a side note I want to point out that although you theoretically play the Phrygian mode on the Em7 in a rhythm changes, you don’t think about the Phrygian mode, just think C major (did that make sense, if not, give me a shout).
| E Phrygian Scale | E F G A B C D |
| Over Em7 | 1 b9 b3 11 5 b6 b7 |
The E Phrygian scale in its root position:
3) The Aeolian Scale
The Aeolian scale (aka relative minor scale) is used to play over minor chords that have a VI function or a I function in minor. An example of a VI is the second chord in a rhythm changes.
| A Aeolian Mode | A B C D E F G |
| Over Am7 | 1 9 b3 11 5 b6 b7 |
The chart for the A Aeolian scale in root position:
4) D Minor Pentatonic Scale or Blues Scale
It can’t get more obvious, very useful, also in a jazz context.
| D Minor Pentatonic | D F G A C |
| Over Dm7 | 1 b3 11 5 b7 |
5) A Minor Pentatonic Scale or Blues Scale
The A minor pentatonic scale sounds very nice over Dm7
| A Minor Pentatonic | A C D E G |
| Over Dm7 | 5 b7 1 9 11 |
6) E minor Pentatonic Scale
The E minor pentatonic works nice if you alternate it with D minor pentatonic (on modal tunes). It creates a tension/release kind of thing (see point 10 on this page)
| E Minor Pentatonic | E G A B D |
| Over Dm7 | 9 11 5 6 1 |
7) D Minor Arpeggio
Surprisingly the Dm7 arpeggio works very well over Dm7
8) Fmaj7 Arpeggio
An Fmaj7 arpeggio over Dm adds the 9: nice sound.
| Fmaj7 Arpeggio | F A C E |
| Over Dm7 | b3 5 b7 9 |
9) Am7 Arpeggio
One step further is Am7, it adds the 11 to the sound.
| Am7 Arpeggio | A C E G |
| Over Dm7 | 5 b7 9 11 |
10) Em7 Arpeggio
Em7 sounds a little more distant over Dm, but works fine if you alternate it with a Dm arpeggio.
D F A C + E G B D = D Dorian Scale
Examples: Triads Over Minor Chords
| Em7 Arpeggio | E G B D |
| Over Dm7 | 9 11 6 1 |
11) Dm6 or Bm7b5 Arpeggio
Emphasizing the 6 of a minor chord works nice if the minor chord has a tonic function and not a sub-tonic function (like in a II V). In other words, the minor chord should be the I, not the II. In other words, the minor chord should not be followed by the V (Dm7 should not be followed by G7).
Example of a minor chord with a tonic function:
| Dm7 | Em7b5 A7 |
| Im7 | IIm7b5 V |
12) G7 Arpeggio
G7 sounds ok over Dm, especially when it has the tonic function. If you use it in a 2 5 1, you can make the b (6) on Dm7 go to #9 and b9 on G7, to the 5 of Cmaj7.
| G7 Arpeggio | G B D F |
| Over Dm7 | 11 6 1 b3 |
13) The Line ClichéIn tunes where the minor chord spans a couple of bars, like in a minor blues, you can use this little device called the line cliché. This technique is as old as the street and is frequently used by gypsy jazz guitarists. The line cliché is a descending line going chromatically from the 1 of a minor chord to its 6:
1 » 7 » b7 » 6
d » c# » c » b
