Modes of the Major Scale

C Lydian Scale on Guitar — 2 Shapes to Play the Whole Neck

C Lydian is one of the seven modes of the major scale — on guitar its notes are C D E F# G A B, built from the formula 1 2 3 #4 5 6 7. Computed live for this exact root and scale, Fretprism finds 2 repeating shapes — the small pattern set you actually need to play it across the whole neck.

C Lydian on the Guitar Fretboard

The notes of Lydian repeat across the guitar fretboard in connected positions. Use the shape below to identify root notes, scale degrees, and neighboring shapes.

Shape 1 of 5

Frets 0–7 (span 7 frets)
Lowest note A, highest note G
2 C root notes, on the A string (fret 3), B string (fret 1)

How to practice this shape

Start on the root — C at fret 3 on the A string. Play up to the highest note in the shape, then back down, staying inside frets 0–7.
Your hand shifts 4 times as you cross strings: E→A (-2), A→D (-1), G→B (-1), B→E (-1). Those crossings — not the notes — are what this position is really asking you to learn.
Once it feels automatic, move on to the next of the 2 shapes — together they cover the whole neck, and the same pattern repeats from there.

What Gives C Lydian Its Sound?

The characteristic sound of C Lydian comes from its augmented 4th.

Every chord in this key

Diatonic chords

These are the 7 chords built from C Lydian's own notes — the ones that will sound like they belong when you're writing a progression, backing a melody, or jamming in this key. The Roman numeral shows each chord's role in the key: capital for major, lowercase for minor, ° for diminished, + for augmented. Not every scale produces a clean chord on every degree — where that happens, we show it honestly instead of forcing a name that doesn't fit.
