G to B is a major third (4 semitones), B to D is a minor third (3 semitones), D to F is a minor third (3 semitones), F to A is a major third (4 semitones), A to C is a minor third (3 semitones). All six notes stacked in thirds, 1 3 5 b7 9 11. The eleventh, C, sits a minor ninth above the third B and clashes with it, so in practice the third is left out: G D F A C is how G11 is usually played, the same notes as G9sus4. Leave out the fifth as well and the engine hears F/G instead (G F A C), so the guitar shapes here keep D.

G11 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 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 dominant eleventh chords on other roots.

Inversions of G11

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 G11 fits

G11 is V11 in C major. The eleventh, C, is the same note as the fourth of a sus chord and wants to fall to the third B; that is why the third is usually left out, and why G11 works as a softer V that delays the pull home. It often moves to G7 before the tonic.
