Banjo C♯7 chord (Sawmill)C♯ seventh on the 5-string banjo: 3 4 1 3, and 4 more shapes

Frets, string 4 to string 1: 3 4 1 3 (first position) · no 5th

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

Sounds: E♯ B C♯ E♯  ·  C♯7 is C♯, E♯, G♯, B (1 · 3 · 5 · ♭7)

The 5th string: the short g adds the ♯4 over C♯7, a colour rather than a clash. This shape leaves out the G♯ it would rub against.

With a capo: on the 1st fret it’s 2 3 0 2 (frets counted from the capo), an open C7 shape. Spike the 5th string at the 6th fret to keep it in tune with the capo.

Sawmill tuning: gDGCD, the short 5th string first, then strings 4 to 1.
