Major Scale on Guitar: Patterns, Formula & Why It Matters

The major scale guitar players learn is the foundation of almost everything in music theory: keys, chords, intervals and modes all start here. This lesson is part of our music theory for guitar beginners series.

Short answer: the major scale is built with the formula whole-whole-half-whole-whole-whole-half (W-W-H-W-W-W-H). On guitar, a whole step is two frets and a half step is one fret, so you can build a major scale from any note on any string. Start with G major at the 3rd fret, then learn the patterns that cover the neck.

Whole Whole Half Formula

The whole whole half formula, written W-W-H-W-W-W-H, is the recipe for every major scale. Here it is applied to C:

Step	From	To	Interval
1	C	D	Whole (2 frets)
2	D	E	Whole
3	E	F	Half (1 fret)
4	F	G	Whole
5	G	A	Whole
6	A	B	Whole
7	B	C	Half

Apply it to G and step 7 lands on F#, not F. That’s why G major has one sharp. Apply it to D and you need F# and C#. Each new key adds a sharp or flat in the order shown on the circle of fifths.

Build a major scale on one string

The easiest way to see the formula is on a single string. On the low E string starting at fret 3 (G), follow W-W-H-W-W-W-H: frets 3, 5, 7, 8, 10, 12, 14, 15. That is G A B C D E F# G. Try the same thing on the A string from fret 3 (C): 3, 5, 7, 8, 10, 12, 14, 15.

Scale degrees

Each note gets a number: 1 2 3 4 5 6 7. Those numbers are how musicians describe chords (a major chord is 1-3-5) and other scales (natural minor is 1 2 b3 4 5 b6 b7). Learning the degrees is what lets you move from memorizing shapes to understanding them.

Major Scale Patterns

A single string is great for understanding, but for playing you need major scale patterns that stay in one area of the neck.

One-octave G major (root on the 6th string)

D|-----------2-4-5-|
A|-----2-3-5-------|
E|-3-5-------------|

Two-octave G major, 2nd position (frets 2–5)

e|----------------------------2-3-5-|
B|------------------------3-5-------|
G|------------------2-4-5-----------|
D|------------2-4-5-----------------|
A|------2-3-5-----------------------|
E|-3-5------------------------------|

Use one finger per fret: index on fret 2, middle on 3, ring on 4, pinky on 5. Move this whole pattern up two frets and it becomes A major; up seven frets and it becomes D major. That’s the beauty of the guitar: the major scale patterns are movable.

The five-position system

To cover the neck, many teachers connect five major scale patterns, each built around a familiar open-chord shape (the CAGED system). Others prefer seven three-notes-per-string patterns, which are great for speed and legato. Either works. Learn the 2nd-position pattern above first, then add one new pattern per week.

Pattern	Root location	Best for
6th-string root (above)	Low E string	Most common keys (F to B)
5th-string root	A string	Keys C, D, Eb in middle positions
Open position	Open strings	C, G and D major
Three-notes-per-string	Any string	Speed, legato, modes
