Banjo Bsus2 chord (Open G)B suspended 2nd on the 5-string banjo: 4 4 2 4, and 4 more shapes

Frets, string 4 to string 1: 4 4 2 4 (first position)

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

Sounds: F♯ B C♯ F♯  ·  Bsus2 is B, C♯, F♯ (1 · 2 · 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.

Open G tuning: gDGBD, the short 5th string first, then strings 4 to 1.
