G locrian pentatonic

The locrian pentatonic is the minor pentatonic with its 5th flattened: root, flat 3rd, 4th, flat 5th, flat 7th. It spells a m7b5 chord plus the 4th, making it the quickest route to a half-diminished sound in familiar pentatonic fingering. Use it over the ii chord in a minor ii-V, or for deliberately unresolved riffing.

it consists of these notes and degrees:

G

I

B♭

bIII

C

IV

D♭

bV

F

bVII

Same notes, different mode

G locrian pentatonic uses the same notes as the scales below. Start from a different note and you get a new mode built on the very same note set.

tip
  • A m7b5 chord plus the 4th: root, b3 (Bb), IV, b5 (Db), b7 (F); the quickest half-diminished vocabulary in a familiar pentatonic grip.
  • It is the minor pentatonic with the 5th lowered: shift that one finger and every box you know turns half-diminished.
  • Over the ii chord of a minor ii-V in the key a whole step below G, this is the pocket-size choice.
  • Use the b5 (Db) as a landing tone here (unlike in the blues scale); over m7b5 harmony it is a chord tone, not a passing note.

How to play G locrian pentatonic on guitar

Open G is a root, so a pedal is available on that string alone under lines built from fret 3 up. It is the only open string in the key, which means the other 5 contribute nothing until you fret them. Fretted roots run 3 on both E strings, 5 on the D, then 8 on the B and 10 on the A. Low E at 3 is the lowest.
