# G Flat Dorian Positions On The Guitar Fretboard

‘G flat dorian’ is the 2nd mode of the F flat major scale. The notes in Gb dorian are:

Gb – Ab – Bbb – Cb – Db – Eb – Fb

F flat major is a rarely used scale. It is enharmonically equivalent to E major. The reason why G flat dorian is a mode of F flat major and not E major is that technically, the second note of E major is F# (not Gb) whereas the second not of Fb is Gb.

If you have read the post on understanding the dorian mode, you will know that the dorian mode contains a flat 3 and a flat 7 (parallel approach). You will also know that it is the 2nd mode of a major scale (derivative approach). Let’s briefly look at how to construct Gb dorian 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 flatten the 3rd note (Bb) and the 7th note (F) we get the following:
Gb – Ab – Bbb – Cb – Db – Eb – Fb

#### Derivative Approach:

Gb is the 2nd note of the Fb major scale:
Fb – Gb – Ab – Bbb – Cb – Db – Eb

If we play an Fb major scale and start on the 2nd note we get the following:

Gb – Ab – Bbb – Cb – Db – Eb – Fb
Let’s look at the Gb dorian mode in the different positions on the guitar fretboard:

#### Positions Along the Fretboard:

Firstly, let’s look at the open position:

Now let’s look at Gb dorian in the 4th position (lowest fret is 4)

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

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

Now let’s look at Gb dorian in the 11th position (lowest fret is 11)

Finally, let’s look at Gb dorian in the 12th position (lowest fret is 12)

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