B SHARP AEOLIAN MODE

‘B Sharp Aeolian’ is the 6th mode of the D sharp major scale. The notes in B# Aeolian are:

B# – Cx – D# – E# – Fx – G# – A#

If you have read the post on understanding the aeolian mode, you will know that the aeolian mode contains a ‘flat 3’, a ‘flat 6’ and a ‘flat 7’ (parallel approach). You will also know that it is the 6th mode of the major scale (derivative approach). The aeolian mode is a very commonly used mode and is also known as the ‘natural minor scale’. Let’s briefly look at how to construct B# aeolian 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 ‘lower’ the 3rd note (Dx), 6th note (Gx) and 7th note (Ax), we get the following:

B# – Cx – D# – E# – Fx – G# – A#

Derivative Approach:

B# is the 6th note of the D# major scale:

D# – E# – Fx – G# – A# – B# – Cx

If we play the D# major scale and start on the 6th note we get the following:

B# – Cx – D# – E# – Fx – G# – A#

Let’s look at the B# aeolian 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 B# aeolian in the 3rd position (lowest fret is 3)

Now let’s look at B# aeolian in the 4th position (lowest fret is 4)

Now let’s look at B# aeolian in the 7th position (lowest fret is 7)

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

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

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