How to play Bsus4
Three notes on one string set. No seventh, so nothing is claimed about the chord beyond its quality.
Thin on their own, excellent over a bass line or against someone else’s harmony.
Bsus4 has 47 of them, on the bottom three strings, the bottom four strings, the high-middle three, the top three strings, the top four strings, the middle four strings, the low-middle three, strings 5-3-2-1 and strings 6-4-3-2, from the 2nd fret up to the 14th — every inversion the chord has: B in the bass, E in the bass and F# in the bass. The one to learn first is the E shape at the 2nd fret, which is the easiest grip here.
6 of them sit on the bottom four strings, 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 xx4457 — no barre and low, at the 4th fret. None of the shapes for Bsus4 uses an open string, so every one of them is movable; the lowest sits at the 2nd fret. 1 of the 6 needs a barre. Together they cover the neck from the 2nd fret to the 14th.

| 7x4457 | 4th fret | B, root position | B | all fretted |
