E Sus4 Triads on Guitar: Every Inversion on Every String Set
A E sus4 triad is E, A and B (1 4 5). It has three arrangements, root position, first inversion and second inversion, and each can be played on four groups of three strings: all twelve shapes are below.

The notes of Esus4
E sus4 is a perfect fourth (five frets) and then a major second, with no third at all. Root position puts E at the bottom (E, A and B); first inversion puts A at the bottom (A, B and E); second inversion puts B at the bottom (B, E and A).
Esus4 replaces the third with the fourth, A. With no third it is neither major nor minor; the fourth wants to fall a semitone or a tone to the third, which is why Esus4 so often resolves to E or Em.
Esus4 on every string set
On the low E, A and D strings: root position at frets 0–9, first inversion at frets 2–5 and second inversion at fret 7.
On the A, D and G strings: root position at frets 4–7, first inversion at frets 0–9 and second inversion at fret 2.
On the D, G and B strings: root position at frets 0–2, first inversion at frets 4–7 and second inversion at frets 9–10.
On the G, B and high e strings: root position at frets 7–10, first inversion at frets 0–2 and second inversion at frets 4–5.
Where the inversions sit in the CAGED shapes
The practice pad above shows Esus4's triads inside each CAGED shape. Use the R, 2, 3 and V switches to see each arrangement:
- Root position: C shape (fret 4), A shape (fret 7), G shape (fret 9) and E shape (fret 12).
- First inversion: C shape (fret 4), G shape (fret 9) and E shape (fret 12).
- Second inversion: C shape (fret 4), A shape (fret 9) and E shape (fret 2).
Where Esus4 appears
Esus4 isn't built on the scale's thirds, so it isn't a diatonic chord in the usual sense, but all three of its notes fit 12 keys: C major (on the 3rd degree), D major (on the 2nd degree), E major (on the 1st degree), G major (on the 6th degree) and A major (on the 5th degree), and C minor (3rd), E minor (1st), F minor (7th), A minor (5th) and B minor (4th).
Of those, C major, D major, E major, G major, A major, E minor, A minor, E harmonic minor and A harmonic minor are keys guitarists play in constantly, because their open strings ring with the scale, so Esus4 turns up often in songs.
Open strings and capo options for Esus4
Four open strings are part of Esus4: the low E string (root), the A string (the third), the B string (the fifth) and the high e string (root). Because the root is among them, you can let it drone under any of the shapes.
Closely related chords
A sus chord is a pause before major or minor: Esus4 keeps the root and fifth and moves the third, so its closest chords share the same root.
