How to play Ebadd9
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.
Ebadd9 has 8 of them, on strings 5-3-2-1 and strings 6-4-3-2, from open position up to the 11th — every inversion the chord has: Eb in the bass, G in the bass, Bb in the bass and F in the bass. The one to learn first is the Bb shape at the nut.
4 of them sit on strings 5-3-2-1, 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 x-x-13-12-x-13 — no barre and only 3 fretted notes. None of the shapes for Ebadd9 uses an open string, so every one of them is movable; the lowest sits at the 3rd fret. 2 of the 4 need a barre. Together they cover the neck from the 3rd fret to the 13th.
| Frets | Where | Bass | Top | Hand |
