The Major Scale

Do-re-mi, on six strings. The major scale — 1, 2, 3, 4, 5, 6, 7, built from the step pattern whole-whole-half-whole-whole-whole-half — is the reference point for every other scale and chord name in Western music. In C: C, D, E, F, G, A, B.

Why it matters even if you solo with pentatonics

Chord names, key signatures, the modes, "b3" and "#4" — all of it is measured against the major scale. Learn it in one key on one octave and the entire vocabulary of music theory becomes readable. And hiding inside it: the major pentatonic is just degrees 1-2-3-5-6, and each of the seven modes is this same scale started from a different note.

The chords it generates

Harmonise the C major scale in thirds and you get the seven diatonic chords — the chord palette of every song in C:

That I–ii–iii–IV–V–vi–vii° pattern holds in every key — see the per-key pages for each key's chords spelled out.

Notes in every key

Positions on guitar

Most players organise the major scale with the CAGED system — five overlapping shapes anchored to the C, A, G, E and D chord forms — or with three-notes-per-string patterns for speed. Either way the payoff is the same: one movable system, twelve keys for free.
