Harmony first
Where this scale fits.
ChordRevelation treats scale choice as a relationship between chord formula, function and target — not as a root-name lookup.
IV degree in major
IV degree in major
A diatonic major chord on IV naturally connects to Lydian within the parent major scale.
Static major harmony
Static major harmony
Strong modal choice when the #4 is intentionally part of the sound.
Fretboard practice
Turn the formula into usable guitar vocabulary.
Keep chord tones visible, compare overlays and practice toward the next chord instead of running patterns without a harmonic destination.
Practice
Target #4
The characteristic tone is the reason to choose Lydian instead of Ionian.
Practice
Compare Ionian
Lower #4 to 4 and hear the tonal center become more conventional.

Use maj7#11 voicings
Match the scale to chord voicings that actually contain or imply #11.
FAQ
Quick answers.
The interval formula is the starting point; Play Over provides the real harmonic context.
What is the formula for lydian mode?
1–2–3–♯4–5–6–7
How should I practice lydian mode on guitar?
Connect the interval formula to chord tones and real harmonic context, then compare positions on the fretboard instead of memorizing a single box.
Can I use lydian mode over every chord with the same root?
No. Scale choice depends on chord quality, harmonic function, key context and the next target chord, not only the root name.
