‘F sharp locrian’ is the 7th mode of the G Major scale. The notes in F# locrian are:

F# – G – A – B – C – D – E

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 F# locrian using both the parallel approach and the derivative approach.

F# Locrian Mode Using The Parallel Approach

F# Major scale has the following notes:

F# – G# – A# – B – C# – D# – E#

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

F# – G – A – B – C – D – E

F# Locrian Mode Using The Derivative Approach

F# is the 7th note of the G Major scale:

G – A – B – C – D – E – F#

If we play the G Major scale and start on the 7th note we get the following:

F# – G – A – B – C – D – E

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

F# Locrian in the 11th Position (Lowest Fret is 11)

F Sharp Locrian Mode 11th Position Frets

That covers the 5 basic positions and the open position of F locrian along the guitar fretboard. For an in depth explanation of the locrian mode, check out locrian mode explained.
