G7sus

G to C is a perfect fourth (5 semitones), C to D is a major second (2 semitones), D to F is a minor third (3 semitones). A dominant seventh with the fourth, C, in place of the third. Like any sus chord it is neither major nor minor. With F in the bass the same four keys read as G7sus4/F.

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 E-shape and A-shape grips 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 seventh suspended fourth chords on other roots.

Inversions of G7sus4

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.
