F7sus4 guitar chord
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.

How to play F7sus4
An open string left ringing against a fretted grip. It costs no finger, so it can sound a note the closed shape has none left for: a tension on top, or a pedal root underneath.
These belong to their key rather than to a shape: they cannot be moved up the neck. D, A, G and E have many; E♭ has a handful.
F7sus4 has 1 of them, only on the bottom four strings, all of them at the 6th fret — all in one inversion, so the bass note never moves. The one to learn first is the Bb shape at the 6th fret, which is the easiest grip here.
Start with xx3546 — no barre and low, at the 3rd fret. None of the shapes for F7sus4 uses an open string, so every one of them is movable; the lowest sits at the 1st fret. 4 of the 7 need a barre. Together they cover the neck from the 1st fret to the 15th.
