‘G flat lydian’ is the 4th mode of the D flat Major scale. The notes in Gb Lydian are:
Gb – Ab – Bb – C – Db – Eb – F
If you have read the post on understanding the lydian mode, you will know that the lydian mode contains a ‘sharp 4’ (parallel approach). You will also know that it is the 4th mode of the major scale (derivative approach). Because the ‘sharp 4’ is the only difference between the lydian mode and the major scale, it is a very simple mode to analyze. Let’s briefly look at how to construct Gb lydian using both the parallel approach and the derivative approach.
Gb Lydian Mode Using The Parallel Approach
The Gb Major scale contains the following notes:
Gb – Ab – Bb – Cb – Db – Eb – F
If we ‘raise’ the 4th note, we get the following:
Gb – Ab – Bb – C – Db – Eb – F
Gb Lydian Mode Using The Derivative Approach
Gb is the 4th note of the Db Major scale:
Db – Eb – F – Gb – Ab – Bb – C
If we play the Db Major scale and start on the 4th note we get the following:
Gb – Ab – Bb – C – Db – Eb – F
Gb Lydian Mode CAGED Positions
Let’s look at Gb lydian in the 5 different CAGED positions along the fretboard.
Gb Lydian in the 1st Position (Lowest Fret is 1)
Gb Lydian in the 2nd Position (Lowest Fret is 2)
Gb Lydian in the 5th Position (Lowest Fret is 5)
Gb Lydian in the 8th Position (Lowest Fret is 8)
Gb Lydian in the 9th Position (Lowest Fret is 9)
