1. String 4 (C): 4th fret, index finger, E
2. String 3 (G): 4th fret, middle finger, B
3. String 2 (B): open, B
4. String 1 (D): 4th fret, ring finger, F♯
5. String 5, the short g: open, G, not in the chord

Sounds: E B B F♯  ·  Bsus4 is B, E, F♯ (1 · 4 · 5)

The 5th string: the short g rubs against the F♯ in this shape, a semitone away: some players let it ring, some skip it.
