Banjo Esus4 chord (Double C)E suspended 4th on the 5-string banjo: 4 4 4 7, and 3 more shapes

Frets, string 4 to string 1: 4 4 4 7 (from the 4th fret)

1. String 4 (C): 4th fret, index finger (barre), E
2. String 3 (G): 4th fret, index finger (barre), B
3. String 2 (C): 4th fret, index finger (barre), E
4. String 1 (D): 7th fret, little finger, A
5. String 5, the short g: open, G, not in the chord

Sounds: E B E A  ·  Esus4 is E, A, B (1 · 4 · 5)

The 5th string: the short g adds the minor 3rd over Esus4, a colour rather than a clash.

With a capo: on the 2nd fret it’s 2 2 2 0 (frets counted from the capo), an open Dsus4 shape. Spike the 5th string at the 7th fret to keep it in tune with the capo.

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