Practice

Guitar only. Everything below is worked out on standard guitar tuning (E A D G B E). The five-box system and the CAGED letters attached to it depend on those exact intervals, so the fret numbers do not transfer to bass, ukulele, mandolin, or an alternate tuning.

The Five Pentatonic Shapes (Guitar)

There are five pentatonic box shapes on the guitar neck — and you only have to learn them once. A minor pentatonic scale and its relative major are the same five notes on the same five shapes; the only thing that changes is which dot you call the root. This page shows the shared dots, the fret window of every box, and how the five chain together up the neck.

Five shapes, not ten: G major pentatonic and E minor pentatonic light identical dots on the fretboard. The major root simply sits three semitones above the minor root.

The idea in one sentence

A minor pentatonic scale and its relative major pentatonic contain exactly the same five pitches, so they light exactly the same dots on the fretboard and produce exactly the same five box shapes. The relative major root sits three semitones (three frets) above the minor root.

That is why the pentatonic system is small. You are not learning five minor shapes and five major shapes — you are learning five shapes, then deciding which dot inside them is home.

One set of dots, two names

Take E minor pentatonic (E · G · A · B · D) and G major pentatonic (G · A · B · D · E). Same five notes, written in a different order. Here they are on the first fifteen frets, high E string at the top: @ marks the root, o marks any other note of the scale, - is a fret that is not in the scale.

G MAJOR PENTATONIC (@ = G)        E MINOR PENTATONIC (@ = E)
  e |o--@-o-o--o-o--@              e |@--o-o-o--o-@--o
  B |o--o-o--@-o-o--o              B |o--o-@--o-o-o--o
  G |@-o-o--o-o--@-o-              G |o-o-o--o-@--o-o-
  D |o-o--@-o-o--o-o-              D |o-@--o-o-o--o-@-
  A |o-o--o-o--@-o-o-              A |o-o--o-@--o-o-o-
  E |o--@-o-o--o-o--@              E |@--o-o-o--o-@--o

Cover the @ symbols and the two grids are indistinguishable, because they are the same grid. The only difference is which of the five dots you resolve to, phrase towards, and land on at the end of a lick — and that single choice is the whole difference between a bright major-pentatonic sound and a dark minor-pentatonic one.

Hear it for yourself: play the E minor pentatonic over an Em chord, then play the identical fingering as G major pentatonic over a G chord.

Where the five boxes sit

Every box holds exactly two notes on every string and spans at most five frets, which is why each one falls under the hand without shifting. Consecutive boxes overlap by about two frets — the overlap is where you change shape without changing note.

The fret windows below are the real windows for two common keys. Because the shapes are movable, the A minor column is simply the E minor column moved five frets up the neck.

Box 1 is the root box. It is the box that carries the root on the low E string at its lowest fret — open E for E minor, fret 5 for A minor. That is exactly where an E-shape barre chord sits, which is why box 1 is paired with the letter E.

The chain wraps. After box 5 the pattern starts again at box 1, twelve frets above where it began. In E minor that means the box 1 that starts at the open strings reappears at the 12th fret, so the whole neck is five shapes repeating.

The CAGED letters attached to the boxes

Read in box order 1 → 5, the conventional CAGED pairing is E · D · C · A · G. Each letter names the movable chord shape that sits inside that box, so a solo played in box 4 is played around an A-shape barre chord.

The letters are a naming convention rather than a derived fact, and they only mean anything in standard tuning — but they are worth knowing, because they connect the scale shape you are soloing in to the chord shape underneath it. The CAGED system page covers the chord side in full.

Why your book may number them differently

This site numbers the five boxes once, anchored on the minor root: box 1 is the root box, and the major pentatonic borrows that same numbering rather than starting its own. One scale, one set of labels, whichever name you are using for the notes.

Many method books instead re-anchor pattern 1 to each scale's own root box on the low E string. Under that convention the major patterns are rotated by one relative to the minor patterns, so minor shape N is the same shape as major shape N−1. Nothing about the fretboard changes; only the labels do. If a book's "major pattern 2" looks like the shape you know as box 3, this is why.

How to practise the five

Start with box 1

Learn the root box first and learn it cold. It is the shape that tells you where you are: the root is on the low E string at the bottom-left of the box, and on the high E string at the same fret.

Practise the seams, not the boxes

Most players get stuck because they drill five boxes and never drill the overlaps. Play box 1 ascending, cross into box 2 in the two frets they share, and come back down. The seam is the skill.

Say the root out loud

Since the dots do not change between relative major and minor, the only thing keeping you oriented is knowing which dot is home. Name it every time you land on it.

Play one shape two ways

Loop an Em chord and solo in box 3. Then loop a G chord and solo in the very same box without moving your hand. Same fingering, two completely different moods — that is the whole lesson in one exercise.

The blues scale uses these same five boxes

The blues scale is the minor pentatonic with one extra note — the b5 — dropped inside it. Nothing is removed, so the five box windows are identical to the ones in the table above; you are adding a note to shapes you already know rather than learning a sixth shape.

Where that added note lands in each box, and how players actually use it, is covered on blues scale shapes on the fretboard.

Take the shapes to the fretboard, then connect them to the chords underneath.
