Banjo Bm7 chord (Sawmill)B minor seventh on the 5-string banjo: 0 4 6 7, and 3 more shapes

Frets, string 4 to string 1: 0 4 6 7 (from the 4th fret)

1. String 4 (D): open, D
2. String 3 (G): 4th fret, index finger, B
3. String 2 (C): 6th fret, ring finger, F♯
4. String 1 (D): 7th fret, little finger, A
5. String 5, the short g: open, G, not in the chord

Sounds: D B F♯ A  ·  Bm7 is B, D, F♯, A (1 · ♭3 · 5 · ♭7)

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

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