What is true of it
E5 is E and B — 1 and 5 counted from E.
The easiest of the 5 fingerings below is 022400: 3 fingers, held at the 2nd 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.
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.
With a different note underneath
E5/B
x22400
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.
