B SHARP DORIAN MODE

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

B# – Cx – D# – E# – Fx – Gx – A#

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 B# dorian using both the parallel approach and the derivative approach.

Parallel Approach:

B# Major has the following notes:
B# – Cx – Dx – E# – Fx – Gx – Ax

If we flatten the 3rd note (Dx) and the 7th note (Ax) we get the following:
B# – Cx – D# – E# – Fx – Gx – A#

Derivative Approach:

B# is the 2nd note of the A# major scale:
A# – B# – Cx – D# – E# – Fx – Gx

If we play an A# major scale and start on the 2nd note we get the following:
B# – Cx – D# – E# – Fx – Gx – A#

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

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

Now let’s look at B# dorian in the 6th position (lowest fret is 6)

Now let’s look at B# dorian in the 10th position (lowest fret is 10)

Finally, let’s look at B# dorian in the 11th position (lowest fret is 11)

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