C Lydian
The C Lydian mode — C D E F# G A B — shown across the guitar neck.
Tap any note on the neck.

C Lydian is the major scale with one note changed — the #4, F#. That single note is what gives the mode its sound: lean on it and the colour is obvious. Leave it out and the melody alone could pass for plain major — then it is the chords underneath that keep the mode.
What is C Lydian?
C Lydian is the seven notes C D E F# G A B — the notes of G major started from its 4th degree, C. Same seven notes as the parent, but with C as home, so the intervals and the sound are different.
C Lydian vs C major
6 of the seven notes are the same. The difference is one note, and that is the whole character of the mode:
- #4 is F# in Lydian, where C major has 4, F.
Play C major and C Lydian back to back over a C chord and listen for F# — that is the note to lean on.
Chords in C Lydian
Stack the mode in thirds and each degree becomes a chord. The home chord is C; the rest are the chords of G major, since the notes are the same — what changes is which one the music rests on. Vamp between C and D and the mode is unmistakable.
C Lydian on the guitar neck
Because C Lydian is G major from its 4th note, its natural fingering is position 4 of the seven three-notes-per-string shapes of G major — the shape whose lowest note is C. Learn that shape with C as home — start and end on it, over a drone on C or the vamp above — and you have the mode under your fingers. Play the same shape with G as home and you hear G major instead. The other six positions are the fingerings for the other six modes of the same key.
How to practice C Lydian on guitar
- Loop position 4 of G major at 60 BPM, starting and ending on C so your ear hears C as home rather than G.
- Hold a C chord (or record one) and play the shape over it. Land on F# on the strong beats — that is the sound of Lydian.
- Hear it harmonized in 3rds on the Fretboard: press Play and every note sounds with its partner while the neck lights up.
The tool draws C Lydian from its own root: the orange dots are on C and the degrees count from it. The notes are its parent key's, G major; to hear Lydian, start and end on C.
