Chords in Db Locrian
Db Locrian is built from the notes Db, Ebb, Fb, Gb, Abb, Bbb and Cb. Its scale carries 10 flats. Harmonising that scale in thirds gives seven chords — 3 majors, 3 minors and 1 diminished — starting on Dbdim as the iø. The chord on the fifth degree is Abb, a major bV, so Db Locrian has the leading tone that makes a Abb-to-Dbdim cadence sound final.
Beyond those seven, Db Locrian commonly borrows Db (I), Ebm (ii), Fm (iii), Gb (IV) and Ab (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 Dbm7b5, Ebbmaj7, Fbm7, Gbm7, Abbmaj7, Bbb7, Cbm7.
