Kind of Blue, Miles Davis’ best-selling album, was released in 1959. The entire album was composed as a series of modal sketches, in which each performer was given a set of modes that defined the parameters of their improvisation. While So What is the most famous tune of the album, All Blues is definitely a runner-up in terms of popularity, and a good addition to your standard repertoire.
All Blues is a 12-bar blues in 6/8, but not a blues in the strict sense of the word. The tune has a lot of bluesy aspects, but it doesn’t have the usual blues chord progression.
In this lesson, you will learn to play the melody of All Blues, the chords, and how to improvise over its form.
All Blues – The Melody
Here is how I usually play All Blues’ theme.
I play most of the melody with single notes, except for a few passages where chords are added.
Listen & Play Along
All Blues – Intro & Chord Vamp
Here’s how you can play the basic accompaniment that’s played by the piano on Miles Davis’ recording of All Blues.
The first 4 measures also work as an intro.
All Blues – Harmonic Analysis & Improvisation
The basic guitar mode you can use to improvise over All Blues is G Mixolydian.
Many people play a C7 in the 5th and 6th measure. This is not entirely correct because the bass keeps playing a G, while the piano player plays variations of C7.
The mode to use on that part of All Blues is G Dorian.
What Can You Play On The G7?
As mentioned above, the first mode of choice over the G7 chord is the G Mixolydian mode:
Don’t limit yourself to this position though, learn to play this scale over the entire neck:
G Major Blues Scale
Another option to play over the G7 is the G major pentatonic scale or the G major blues scale.
Here’s the root position of the G major blues scale (again, don’t limit yourself to this position, use the entire neck). The blue notes are shown in blue. Use them to slide, hammer or pull into the 9 or 3.
G Minor Blues Scale
Another option to play over G7 is the G minor pentatonic scale or the G minor blues scale.
Example 1 – G7
Because of the bluesy nature of the song, double stops and such also work well (last bar).
Example 2 – G7
In modal songs, you’ve got to find ways to make your solos interesting because the harmony doesn’t help you much. One of the things you can do is put some large intervals in your soloing lines.
This example uses major and minor sixths in the G Mixolydian scale.
Example 3 – G7
Using arpeggios with a lot of tensions can also help to open the sound in modal tunes.
In the first bar of this example, I play an Fmaj7 arpeggio over G7.
|Played over G7||b7||9||4||13|
In bar 2, I play a Bm7b5 arpeggio over G7, which produces a 9 sound.
|Played over G7||3||5||b7||9|
What can you play on the Gm6 (C7) in bars 5 and 6?
G Dorian Mode
The most obvious scale choice to play over the Gm6 (or C9, depending on how you look at it), is the G Dorian mode (=C Mixolydian mode).
G Minor Blues Scale
An option that works well is to play G Mixolydian on the G7 of bars 1-4 and play the G minor blues scale on C7 in bars 5-6.
If you start with the G blues on the G7 you get bored of the sound sooner and the effect is more dramatic if you introduce the G blues scale on the C7.
Example 4 – G7, the transition to C7, and C7
In this example I want to show you 3 things:
1. In the first 3 bars, I use a phrase that is transposed. Motivic melodies like this work well on modal tunes and grab the listener’s attention.
2. Although there is no real modulation to C7 in the 5th bar because the bass stays G, it sounds like it is going to C7 because the harmony changes to G minor. Because of this, you can use what you usually play on a blues.
In the 4th bar, for example, I use the G altered scale, as I would normally do to go to C7.
3. In the 2 last bars, I use a G Dorian scale.
What can you play on the D7#9 and Eb7#9?
The D7#9 and Eb7#9 in bars 9 and 10 are the hardest part of All Blues’ chord changes.
These chords are normally used on a minor blues, but here they are used in the context of a major blues.
The tensions used by Miles Davis make it hard to tell which scale he was thinking of. This is purely a theoretical thing and doesn’t matter so much, but it makes it interesting none the less.
Miles Davis uses a #9 and a natural 5th on both chords in his solos. Usually, an altered scale is used on a #9 scale, but an altered scale has a b5 and a #5, but no natural 5.
Theoretically, I can think of 2 scales where this could come from:
The Half-Whole Diminished Scale
Use the D half-whole diminished scale (aka dominant diminished scale) on D7#9 and the Eb half-whole diminished scale on Eb7#9.
The G Harmonic Minor Scale
On D7, use the G harmonic minor scale with an added b7 (the #9 of D7).
You can also alter the chords completely and play the D altered scale on D7#9 and Eb altered scale on Eb7#9.
Example 5 – D7#9 Eb7#9
In this example, I play the G harmonic minor scale with added b7 (the second note).
Example 6 – D7#9 Eb7#9
This example uses simple dominant 7 arpeggios mixed with chromatic notes.
Example 7 – D7#9 Eb7#9
In the next example, I emphasize the #9 (f) and finish with a simple chromatic idea in the last measure.
Example 8 – D7#9 Eb7#9
In this last example, I use 2 minor pentatonic scales.
D minor pentatonic over D7#9:
|D Minor Pentatonic Scale||D||F||G||A||C|
|Played over D7#9||1||#9||11||5||b7|
And Eb minor pentatonic over Eb7#9.
