A Flat Phrygian Mode on the Guitar – 5 CAGED Positions, Tabs and Theory

‘A Flat phrygian’ is the 3rd mode of the F flat major scale. The notes in Ab Phrygian are:

Ab – Bbb – Cb – Db – Eb – Fb – Gb

The phrygian mode has a dark sound, which can be used over minor chords to create interesting and exotic musical ideas.

If you have read the post on understanding the phrygian mode, you will know that the phrygian mode contains a ‘flat 2’, a ‘flat 3’, a ‘flat 6’ and a ‘flat 7’ (parallel approach).

You will also know that it is the 3rd mode of a major scale (derivative approach). Let’s briefly look at how to construct Ab Phrygian using both the parallel approach and the derivative approach.

Ab Phrygian Mode Using The Parallel Approach

A Flat Major has the following notes:

Ab – Bb – C – Db – Eb – F – G

If we ‘flatten’ the 2nd note (Bb), the 3rd note (C), the 6th note (F) and the 7th note (G) we get the following:

Ab – Bbb – Cb – Db – Eb – Fb – Gb

Ab Phrygian Mode Using The Derivative Approach

Ab is the 3rd note of the Fb major scale:

Fb – Gb – Ab – Bbb – Cb – Db – Eb

If we play the Fb major scale and start on the 3rd note we get the following:

Ab – Bbb – Cb – Db – Eb – Fb – Gb
