# G FLAT LYDIAN MODE

‘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.

## Parallel Approach:

Gb Major has 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

## 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

Let’s look at the Gb lydian mode in the different positions on the guitar fretboard:

## Positions Along the Fretboard:

None of the notes in Gb lydian can be played on the open strings of the guitar. Therefor, it is said that there is no ‘open position’ for Gb lydian. Let’s look at the positions along the fretboard.

Firstly, let’s look at Gb lydian in the 1st position (lowest fret is 1)

Now let’s look at Gb lydian in the 2nd position (lowest fret is 2)

Now let’s look at Gb lydian in the 5th position (lowest fret is 5)

Now let’s look at Gb lydian in the 8th position (lowest fret is 8)

Finally, let’s look at Gb lydian in the 9th position (lowest fret is 9)

That covers the 5 basic positions and the open position of Gb lydian along the guitar fretboard.
