Banjo Fsus4 chord (Open G)F suspended 4th on the 5-string banjo: 3 3 1 3, and 4 more shapes

Frets, string 4 to string 1: 3 3 1 3 (first position)

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

Sounds: F B♭ C F  ·  Fsus4 is F, B♭, C (1 · 4 · 5)

The 5th string: the short g adds the 9th over Fsus4, a colour rather than a clash.

With a capo: on the 3rd fret it’s 0 2 3 5 (frets counted from the capo), an open Dsus4 shape. Spike the 5th string at the 8th fret to keep it in tune with the capo.

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