The Major Pentatonic Scale on Guitar: Same Shapes, Different Root

The major pentatonic scale is five notes: root, second, third, fifth and sixth. In C that's C, D, E, G and A. It uses exactly the same shapes as the minor pentatonic — C major pentatonic is A minor pentatonic with C as home — so to find it in any key, play the minor shapes three frets below the major root.

What the major pentatonic is

If you already know the minor pentatonic, you know every shape in this guide. That's the point of it. The pentatonic scale guide covers the five positions in full; this one is about using those same shapes to sound major. It's part of the pentatonic lessons.

The major pentatonic's formula is 1, 2, 3, 5, 6. It's the major scale with two notes removed — the fourth and the seventh, the two that form semitone steps and are most likely to clash with chords. What's left is bright, open and very hard to make sound wrong over a major chord. It's the sound of a lot of country, pop and southern rock soloing, and of major-key melodies far beyond the guitar.

Compare it with the minor pentatonic's 1, ♭3, 4, 5, ♭7. The major version has a major third where the minor has a flat third, and a sixth where the minor has a flat seventh. Those two differences are what make one sound bright and the other bluesy.

Same shapes, different root

C major pentatonic (C, D, E, G, A) and A minor pentatonic (A, C, D, E, G) contain exactly the same five notes. They're relatives: the same set of notes heard from a different home. So the five A minor pentatonic positions are also the five C major pentatonic positions. Nothing about the fingering changes. What changes is which notes you treat as roots, where you start and end your phrases, and which notes you lean on.

Here is the shape most players use for C major pentatonic, around the 8th fret. It's the same frets as the second A minor position, but labelled from C.

The roots sit at the 8th fret of the low E string, the 10th fret of the D string and the 8th fret of the high e. Start and end phrases there, and lean on the third (E) and fifth (G), and the same frets you use for A minor will sound unmistakably major.

The same is true of every position. If you can play A minor pentatonic across the neck, as covered in breaking out of the pentatonic box, you can play C major pentatonic across the neck. You just need to know where the Cs are.

The three-frets-down trick

The relative minor is always three frets below the major root, on the same string. So the quickest way to play the major pentatonic in any key is to take the minor pentatonic shape you know best — usually position 1 — and move it down three frets from where the minor version would be.

Say you want A major pentatonic. A minor pentatonic position 1 has its root at the 5th fret of the low E string. Move the same shape down three frets, to the 2nd fret, and you're playing F♯ minor pentatonic — which is A major pentatonic.

In this shape the A roots are at the 5th fret of the low E string, the 2nd fret of the G string and the 5th fret of the high e. The shape is the one under your fingers already; the job is retraining your ear to hear those As as home rather than the notes at the 2nd fret of the low E string.

It works in every key. G major pentatonic is the E minor box at the open position or 12th fret; D major pentatonic is the B minor box at the 7th fret; E major pentatonic is the C♯ minor box at the 9th fret.

When to use the major pentatonic

Over major keys and major chords

If a song is in a major key and the chords sound happy rather than bluesy, the major pentatonic of that key is the safe, melodic choice. Over a progression in C — C, F, G, Am — C major pentatonic fits throughout. Land on C, E or G over the C chord and the solo will sound settled.

Following the chords

In country and rock'n'roll, players often switch to the major pentatonic of each chord as it changes: A major pentatonic over A, D major pentatonic over D, E major pentatonic over E. Because all the positions share shapes, that's a matter of moving the same box to each chord's root.

Mixing major and minor over the blues

Over a 12-bar blues, many players use both. The minor pentatonic gives grit; the major pentatonic gives a sweeter, more country sound. A common move is to play the major pentatonic's third and then the minor's flat third, or slide between them. In A, that's C♯ and C, one fret apart.

When not to use it

Over a minor chord or a minor key, the major pentatonic of the same root clashes: its major third fights the chord's minor third. Over A minor, use A minor pentatonic (or its relative, C major pentatonic, which is the same notes).

A ten-minute practice routine

1. Two minutes — find the roots. In the C major shape around the 8th fret, play only the Cs, then add the Es and Gs. That's the C major chord hiding inside the scale.
2. Three minutes — phrases that end on the root. Over a C drone or a C major backing track, play short phrases that finish on C. Then finish them on E, then on G.
3. Two minutes — the same frets in minor. Change the backing to A minor and play the same shape ending on A. Hear the mood change while your fingers stay put.
4. Three minutes — a new key. Use the three-frets trick to play A major pentatonic from the box at the 2nd fret, ending phrases on the As.

Do this for a week and the shapes will stop belonging to one key or mood. They'll be five patterns you can point at whichever root the music needs. To go further, the CAGED system shows which major chord shape each position surrounds, so you can find chord tones without thinking.
