B FLAT LOCRIAN MODE

‘B Flat Locrian’ is the 7th mode of the C flat major scale. The notes in Bb Locrian are:

Cb – Db – Eb – Fb – Gb – Ab – Bb

If you have read the post on understanding the locrian mode, you will know that the locrian mode contains a ‘flat 2’, a ‘flat 3’ a ‘flat 5’ a ‘flat 6’ and a ‘flat 7’ (parallel approach). You will also know that it is the 7th mode of the major scale (derivative approach). The locrian mode is a very ‘dark’ sounding mode and is probably the hardest of the 7 modes to get acquainted with. Let’s briefly look at how to construct Bb locrian using both the parallel approach and the derivative approach.

Parallel Approach:

Bb major scale has the following notes:

Bb – C – D – Eb – F – G – A

If we ‘lower’ the 2nd note (C), 3rd note (D), 5th note (F), 6th note (G) and 7th note (A), we get the following:

Cb – Db – Eb – Fb – Gb – Ab – Bb

Derivative Approach:

Bb is the 7th note of the Cb major scale:

Cb – Db – Eb -Fb – Gb – Ab – Bb

If we play the Cb major scale and start on the 7th note we get the following:

Cb – Db – Eb – Fb – Gb – Ab – Bb

Let’s look at the Bb locrian mode in the different positions on the guitar fretboard:
