Under the hand. 1 of the 8 shapes here sits in open position, and the first uses 1 open string with 1 left unplayed. None of them needs a barre. Together they cover the neck from the 1st fret to the 13th.
Where it goes. Ebalt is a dominant with its tension raised, so it still points at Ab — harder than a plain seventh does, because the altered tones sit a semitone from where they are going.
Shell. Root, third and seventh: the guide tones fix the quality, so the fifth is dropped. That is what leaves a string free, so pick a tension to put on top. Ebalt has xx1020, x6565x, 11-10-11-9-x-x, x-x-13-12-14-12, x6x020, x6x687, 11-x-11-12-12-x, x6x027.
Rootless. The root left to the bass player. Frees a finger for a tension. Ebalt has xx2423, x2202x, x4545x, xx5657, xx9989, x-x-11-12-12-12, x-14-14-12-14-x, x2x020.
Open string. An open string left ringing against a fretted grip. Because it costs no finger, it sounds a note the closed shape has none left for -- a tension on top, or a pedal root underneath. Either a familiar grip with open strings added, or a shape so sparse the open strings carry the chord. These belong to their key rather than to a shape, so D, A, G and E have many and Eb a handful.
