Formula

Semitones

G to A is a major second (2 semitones), A to D is a perfect fourth (5 semitones). The third is replaced by the second (A), so the chord is neither major nor minor. The same three keys with D in the bass read as Dsus4.

Gsus2 on the guitar

Standard tuning (E A D G B E). Strings run low E on the left to high e on the right, frets downwards; × is a muted string, ○ an open string, and each dot shows the note it sounds, with the root in blue-green. Every shape below has G as its lowest note.

The barre shapes are movable: an E-shape chord's root is the note under your first finger on the low E string, an A-shape chord's root is the note on the A string. Slide the same grip up or down to play suspended second chords on other roots.

Inversions of Gsus2

An inversion puts a note other than the root in the bass. The name is what semicord's chord finder calls those notes played bottom to top; a slash name like C/E means a C chord with E in the bass.

Where Gsus2 fits

A sus chord has no third, so it is neither major nor minor and has no fixed place in a key. In Gsus2 the second, A, usually rises to the major or minor third or falls back to the root G; it is also often left unresolved as a colour, especially on guitar.
