Banjo Gaug chord (Open D)G augmented on the 5-string banjo: 1 1 2 1, and 3 more shapes

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

1. String 4 (D): 1st fret, index finger (barre), D♯
2. String 3 (F♯): 1st fret, index finger (barre), G
3. String 2 (A): 2nd fret, middle finger, B
4. String 1 (D): 1st fret, index finger (barre), D♯
5. String 5, the short f♯: open, F♯, not in the chord

Sounds: D♯ G B D♯  ·  Gaug is G, B, D♯ (1 · 3 · ♯5)

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

With a capo: on the 5th fret it’s 0 0 1 0 (frets counted from the capo), an open Daug shape. Spike the 5th string at the 10th fret to keep it in tune with the capo.

Open D tuning: f♯DF♯AD, the short 5th string first, then strings 4 to 1.
