guitar chord
E♭sus4
The third replaced by the fourth, which leans on the third it is standing in for.
Written the other way round it is D♯sus4 — the same twelve keys on a piano, a different piece of notation.

What is true of it
E♭sus4 is E♭, A♭ and B♭ — 1, 4 and 5 counted from E♭.
These are also the notes of A♭sus2/E♭ and G♯sus2/E♭. Which name is right depends on what is underneath and what came before — the notes alone do not decide.
The easiest of the 5 fingerings below is bbddbb: 3 fingers, one of them barring the 11th fret, held at the 11th fret.
None of them uses an open string, so this chord moves up the neck unchanged — the same shape 1 fret higher is the chord a semitone above.
3 of the 5 need a barre.
Where its notes are on the neck
The brass dots are E♭, the root. Everything else is a chord tone with its degree printed in it.

An inversion is the same chord with a different note lowest. The name changes to a slash name because the bass is what a listener hears as the foundation.
