Allan Holdsworth's 10 Most Usable Scales

Table of Contents

Introduction

In 1992, REH released a video for Allan Holdsworth. In it, he gave a little glimpse of his process. His way of displaying and treating scales was of paramount importance.

Included with each of the scale diagrams is a list of the Common Chords which can be derived from that scale.

This article is a work in progress and this topic deserves much expansion, which will be implemented gradually. For the time being, please enjoy this initial listing!

No 1 D Dorian

Allan's symbol: Dx 1 – 2 – b3 – 4 – 5 – 6 – b7

D Dorian scale, full-neck fretboard diagram, Fretly rendering
  • Allan’s symbol: Dx
  • This scale is the second mode of the C Major Scale. Holdsworth actually defined this scale in his video as the “C, Dm, G7” scale. We know that Allan, not unlike Pat Martino, preferred ‘conversion to minor’ whenever possible so the scale is named not as C major a type of D minor scale, which for jazz-improvisation is actually much more efficient. As Allan said in this 1991 interview: “Basically I have a way of breaking down chords into scales and I usually take them to the nearest relative minor and I work on it from there.”

On 13 September 2014 there was a “meet & greet” with Allan Holdsworth in The Cutting Room in NYC. Here, Allan discussed his approach and concepts more in-depth than he would typically do or was known for.

In this ‘part 3’ of the highly recommended recordings of that meet & greet, he explains how he looks at the notes within an octave as a circle, instead of, say, a row and he showed a graphic of his interpretation of such a circle.

He explains how he arrived at his personal concept of approaching the C major scale from the second degree (the D dorian mode), and using it as a vantage point. The reason for this is that he looked at the circle visualization of the scale and found it to be perfectly symmetrical when the D is at 12 o’clock. This is also how he arrived at his naming convention of the ‘x’ as the most basic scale type.

So, in a way not unlike Pat Martino’s approach, he uses ‘conversion to minor’, looking at each scale preferably as a variant of the dorian mode.

The practice of visualizing scales in this way comes from Musical Set Theory, as a way to visualize pitch classes, a system that takes a highly mathematical approach to music and is more commonly used in the world of classical music, especially amongst scholars and composers. A good example of this is the Chromatic Circle.
