A dorian is the 2nd mode of the G Major scale. The notes in the A dorian mode are:

A – B – C – D – E – F# – G

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 A dorian using both the parallel approach and the derivative approach.

A Dorian Mode Using The Parallel Approach

The A Major scale contains the following notes:

A – B – C# – D – E – F# – G#

If we flatten the 3rd note (C#) and the 7th note (G#) we get the following:

A – B – C – D – E – F# – G

A Dorian Mode Using The Derivative Approach

A is the 2nd note of a G major scale:

G – A – B – C – D – E – F#

If we play a G major scale and start on the 2nd note we get the following:

A – B – C – D – E – F# – G

A Dorian in the Open Position

Let’s look at the A dorian mode in the different positions on the guitar fretboard:

Firstly, let’s look at the open position:

A Dorian CAGED Positions

Now let’s look at A dorian in the 5 different CAGED positions along the fretboard.

A Dorian in the 2nd Position (Lowest Fret is 2)

A Dorian Mode 2nd Position Frets
A Dorian Mode 2nd Position Notes

A Dorian in the 3rd Position (Lowest Fret is 3)

A Dorian Mode 3rd Position Frets
A Dorian Mode 3rd Position Notes

A Dorian in the 7th Position (Lowest Fret is 7)

A Dorian Mode 7th Position Frets
A Dorian Mode 7th Position Notes

A Dorian in the 8th Position (Lowest Fret is 8)

A Dorian Mode 8th Position Frets
A Dorian Mode 8th Position Notes

A Dorian in the 11th Position (Lowest Fret is 11)

A Dorian Mode 11th Position Frets
A Dorian Mode 11th Position Notes

That covers the 5 basic positions and the open position of A dorian along the guitar fretboard. For an in depth explanation of the dorian mode, check out dorian mode explained.
