How to play Abalt
Root, third and seventh. The third and seventh, the guide tones, are what make the chord major, minor or dominant, so the fifth can go: it says nothing the symbol needs.
Three notes means a spare string, which is the real point. Put a tension on it.
Abalt has 5 of them, on the bottom four strings, the top four strings, the middle four strings, strings 6-4-3-2 and strings 5-3-2-1, from the 2nd fret up to the 11th — all in one inversion, so the bass note never moves. The one to learn first is the Ab shape at the 2nd fret, which is the easiest grip here.
Start with xx6534 — low, at the 3rd fret. None of the shapes for Abalt uses an open string, so every one of them is movable; the lowest sits at the 3rd fret. None of them needs a barre. Together they cover the neck from the 3rd fret to the 13th.
