A major

The major scale is the reference point of Western harmony: seven notes in the familiar whole and half step pattern, with a leading tone that pulls firmly back to the root. Chords, key signatures and all seven modes are measured against it. It resolves so naturally that it carries most pop, folk, classical and country writing, and learning it across the whole fretboard gives you the map every other scale on this site is drawn on.

it consists of these notes and degrees:

tip
  • Map the A major scale through all five CAGED positions, then practice moving between neighboring positions along one string so the whole neck connects.
  • Over a I-IV-V progression in A, land chord tones on the downbeats: root, 3rd (C#) and 5th (E) of whichever chord is sounding.
  • The scale's pull comes from its half steps: resolve the leading tone (G#) up to A and the 4th (D) down to the 3rd (C#) to make phrases sound finished.
  • Harmonize the scale in diatonic 3rds and 6ths on adjacent string pairs; it is instant melodic rhythm-guitar vocabulary in A.

How to play A major on guitar

Open A gives the root a home on the fifth string, so bass-note drones under key-of-A lines cost nothing. Both E strings ring the fifth open and open D adds the fourth, which means five of the six open strings support the key. A-shape barre tops out at fret 12, with the E-shape down at fret 5. Three sharps define the key. F# minor shares the full fingering 9 semitones above the tonic, so relative-minor ideas transfer without moving your hand.
