E to G# is a major third (4 semitones), G# to B is a minor third (3 semitones), B to D is a minor third (3 semitones), D to F# is a major third (4 semitones). A dominant seventh (E7) with the ninth, F#, on top. Guitarists usually leave out the fifth, B; the chord still reads as E9 while the third G# and seventh D are there.

E9 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 E 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 ninth chords on other roots.

Inversions of E9

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 E9 fits

E9 is V9 in A major. It resolves like E7. In funk and blues it is also played as I9, IV9 and V9 of a twelve-bar blues, with no pull to resolve at all. Without the root, its upper four notes G# B D F# are G#m7b5, which is why pianists who leave the root to the bass player grab that shape.
