Major Scale on Guitar — Formula, Chords & Fretboard
The major scale is the reference system for interval names, diatonic chords and the seven modes. Understanding it as degrees makes transposition much easier.

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.
Modal parent collection
Modal parent collection
Ionian is the major scale itself; Dorian through Locrian can be viewed as rotations of the same pitch collection.
Improvisation
Improvisation
Across a diatonic progression, one major scale can describe the common key while chord tones define each moment.
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
Name the degrees
Always know 1 through 7, not only note names.

FAQ
Quick answers.
The interval formula is the starting point; Play Over provides the real harmonic context.
What is the formula for major scale?
1–2–3–4–5–6–7
How should I practice major scale 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 major scale 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.

Open the approach on the fretboard, compare chord tones with tensions, keep multiple overlays visible and use the next chord as the resolution target.
