‘D flat mixolydian’ is the 5th mode of the Gb Major scale. The notes in Db Mixolydian are:

Db – Eb – F – Gb – Ab – Bb – Cb

If you have read the post on understanding the mixolydian mode, you will know that the mixolydian mode contains a ‘flat 7’ (parallel approach). You will also know that it is the 5th mode of the major scale (derivative approach).

Because the flat 7′ (or ‘lowered 7’) is the only difference between the mixolydian mode and the major scale, it is a very simple mode to analyze.

The Db mixolydian mode is the default scale that is used to improvise over Db dominant 7 chords.

Let’s briefly look at how to construct Db mixolydian using both the parallel approach and the derivative approach.

Db Mixolydian Mode Using The Parallel Approach

Db Major has the following notes:

Db – Eb – F – Gb – Ab – Bb – C

If we ‘lower’ the 7th note, we get the following:

Db – Eb – F – Gb – Ab – Bb – Cb

Db Mixolydian Mode Using The Derivative Approach

Db is the 5th note of the Gb major scale:

Gb – Ab – Bb – Cb – Db – Eb – F

If we play the Gb major scale and start on the 5th note we get the following:

Db – Eb – F – Gb – Ab – Bb – Cb
