What chord is this? I thought maybe E(add2)/B?
The top line is treble and the bottom is bass
In the key of D, as suggested by comments, this chord is a Bsus4, with B-B-B-E-F♯, where the minor 3rd of the vi chord (D of Bm) has been replaced by the 4th (E).
With so many Bs in the spelling, I would be inclined to call this chord a Bsus4, but it may also be an inversion of an Esus2, where the minor 3rd of the ii chord (G of Em) has been replaced by the 2nd (F♯).
(I assume there is no key signature.)
First of all, we can safely assume that the root note is B, since it is played in three different octaves. The other notes are E and F.
The dominant note in B is F#, meaning that this must be a diminished chord. The E is the subdominant note in B minor, so this chord would be a suspension of the fourth.
There is, of course, another less likely possibility
It is most likely that this is a diminished chord with a suspension, however it's also possible that this is E with a suspension (Esus2).
In second inversion, this has the correct notes to be a suspended second chord on E (B E
G F), however the G is missing.
In resonse to the OP's comment
This is actually in the key of D major / B minor:
The notes of this chord are B, E, and F#. This is a B minor chord with a suspension on the fourth (some might call it Bsus4).
