Seventh chords
Same notes, different home note
G# Locrian uses exactly the same notes as C# Phrygian, D Lydian, E Mixolydian, F# natural minor, A major and B Dorian. What changes is the note the music keeps returning to, and with it which chord sounds like home.
Same notes as the key of A major: the chords are the same seven, but with G# as home.
How G# Locrian is built
Locrian has a minor 2nd and a diminished 5th: against G# natural minor, A# becomes A and D# becomes D. It has the same notes as A major, played from its 7th note. Because its 5th is flattened, the chord on its root is diminished (G#dim), which is unstable, so whole songs are rarely in Locrian. Jazz players use it over the half-diminished chord G#m7b5.

What this page cannot do
- One spelling per scale. the root is spelled the way that needs the fewest sharps and flats.
- Equal temperament only. Blues and many folk traditions bend notes between these pitches, and Arabic and Turkish maqam scales use quarter tones that a piano cannot play.
- The guitar diagram shows standard tuning only and does not suggest fingerings; any note can be played in several places.
- The sound is a simple synthesised tone made in your browser, not a recorded instrument.
