# B Flat Dorian Mode on the Guitar – 5 CAGED Positions, Tabs and Theory

‘B flat dorian’ is the 2nd mode of the A flat major scale. The notes in Bb dorian are:

Bb – C – Db – Eb – F – G – Ab

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

## B Flat Dorian Mode Using The Parallel Approach

Bb major scale has the following notes:

Bb – C – D – Eb – F – G – A

If we flatten the 3rd note (D) and the 7th note (A) we get the following:

Bb – C – Db – Eb – F – G – Ab

## B Flat Dorian Mode Using The Derivative Approach

Bb is the 2nd note of the Ab major scale:

Ab – Bb – C – Db – Eb – F – G

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

Bb – C – Db – Eb – F – G – Ab

## B Flat Dorian in the Open Position

Firstly, let’s look at Bb dorian in the open position:

## B Flat Dorian CAGED Positions

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

### Bb Dorian in the 12th Position (Lowest Fret is 12)

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