Eadd9 is E, G#, B and F# — E with the ninth added, and no seventh.
It sounds bright and ringing. No seventh at all: that is what “add” means, and it is why this sounds open where a maj9 sounds lush.

Tonic — a triad with one colour on it.
Also written E(add9), Eadd2 or E add nine. The same chord either way; which spelling you meet depends on who wrote the chart.
The same operation one voice further down: the third voice from the top falls an octave and becomes the bass.
That leaves a bigger hole under the top three notes, so a string gets skipped: the muted string in the middle is the shape, not a mistake.
Eadd9 has 9 of them, on strings 6-4-3-2 and strings 5-3-2-1, from open position up to the 12th — every inversion the chord has: E in the bass, G# in the bass, B in the bass and F# in the bass. The one to learn first is the F# shape at the nut.
5 of them sit on strings 6-4-3-2, so you can run the inversions up one set without changing strings — which is the whole reason to learn them as a family rather than as separate grips.
Start with xx21x2 — no barre and only 3 fretted notes. 1 of the 6 shapes here sits in open position. 3 of the 6 need a barre. Together they cover the neck from the 1st fret to the 14th.
