Chords in F Locrian
F Locrian is built from the notes F, Gb, Ab, Bb, Cb, Db and Eb. Its scale carries 6 flats. Harmonising that scale in thirds gives seven chords — 3 majors, 3 minors and 1 diminished — starting on Fdim as the iø. The chord on the fifth degree is Cb, a major bV, so F Locrian has the leading tone that makes a Cb-to-Fdim cadence sound final.
Beyond those seven, F Locrian commonly borrows F (I), Gm (ii), Am (iii), Bb (IV) and C (V) from the parallel major — the mixture chords that give a progression somewhere unexpected to go.
The seven chords
Extended to four notes each, the same seven degrees give Fm7b5, Gbmaj7, Abm7, Bbm7, Cbmaj7, Db7, Ebm7.
