‘A Flat Aeolian’ is the 6th mode of the C flat major scale. The notes in Ab Aeolian are:

Ab – Bb – Cb – Db – Eb – Fb – Gb

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 Ab aeolian using both the parallel approach and the derivative approach.

A flat aeolian is often referred to as the A flat natural minor scale. The natural minor scale is often viewed as the default minor scale for theoretical purposes.

Ab Aeolian Mode Using The Parallel Approach

Ab Major has the following notes:

Ab – Bb – C – Db – Eb – F – G

If we flatten the 3rd note (C), the 6th note (F) and the 7th note (G) we get the following:

Ab – Bb – Cb – Db – Eb – Fb – Gb

Ab Aeolian Mode Using The Derivative Approach

Ab is the 6th note of the Cb major scale:

Cb – Db – Eb – Fb – Gb – Ab – Bb

If we play the Cb Major scale and start on the 6th note we get the following:

Ab – Bb – Cb – Db – Eb – Fb – Gb
