‘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.

B Sharp Dorian Mode Using The 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#

B Sharp Dorian Mode Using The 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:

B Sharp Dorian CAGED Positions

Let’s look at B# dorian in the 5 different CAGED positions along the fretboard.
