Banjo Bsus2 chord (Double C)B suspended 2nd on the 5-string banjo: 1 4 1 4, and 3 more shapes

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

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

Sounds: C♯ 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.

With a capo: on the 4th fret it’s 2 2 2 0 (frets counted from the capo), an open Gsus2 shape. Spike the 5th string at the 9th fret to keep it in tune with the capo.

Double C tuning: gCGCD, the short 5th string first, then strings 4 to 1.
