Same notes, different home note

F# Locrian uses exactly the same notes as C Lydian, D Mixolydian, E natural minor, G major, A Dorian and B Phrygian. What changes is the note the music keeps returning to, and with it which chord sounds like home.

Same notes as the key of G major: the chords are the same seven, but with F# as home.

How F# Locrian is built

Locrian has a minor 2nd and a diminished 5th: against F# natural minor, G# becomes G and C# becomes C. It has the same notes as G major, played from its 7th note. Because its 5th is flattened, the chord on its root is diminished (F#dim), which is unstable, so whole songs are rarely in Locrian. Jazz players use it over the half-diminished chord F#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.
