Bb Lydian on the guitar
Standard tuning, high e on top as in tablature, open strings to fret 12. Every dot is a note of the scale; the pattern repeats from fret 12 up.
The seven chords of Bb Lydian
Every other note of the scale stacked on each note. Numerals are measured against the major scale on Bb, so a b marks a chord root a semitone lower than in major.
Seventh chords
Same notes, different home note
Bb Lydian uses exactly the same notes as C Mixolydian, D natural minor, E Locrian, F major, G Dorian and A 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 F major: the chords are the same seven, but with Bb as home.
How Bb Lydian is built
Lydian is the major scale with a raised 4th: against Bb major, Eb becomes E. It has the same notes as F major, played from its 4th note. The raised 4th, E, is a tritone above the root, and it makes the chord on the 2nd note major (C); Bb to C and back is the bright, floating Lydian sound used in a lot of film music.

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.
