Eb to G is a major third (4 semitones), G to Bb is a minor third (3 semitones), Bb to F is a perfect fifth (7 semitones). A major triad with the ninth, F, added and no seventh. The ninth is the second of the scale an octave up, so with F played right next to the root the same chord is often written Ebadd2. It is not Ebsus2: the third G is still there.

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 Eb 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 major add nine chords on other roots.

Inversions of Ebadd9

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 Ebadd9 fits

Ebadd9 is I in Eb major, IV in Bb major, V in Ab major. The added F belongs to all three of those keys, so Ebadd9 can stand in for Eb wherever it appears; it keeps the major sound but softens it. It is not a substitute for Eb9, which also has the seventh Db.
