B6 chords on Banjo

Playing this B6 voicing

The 4-4-4-6 diagram uses the four long strings in open-G tuning (g D G B D). Pick strings 4 through 1 and skip or mute the short fifth-string g.

Place an index-finger barre across the four long strings at fret 4, then put your ring finger on string 1 at fret 6. Pick strings 4, 3 and 2 to check the barre before adding string 1; avoid letting the ring finger touch string 2.

If you have just played the A6 shape (2-2-2-4), move the whole grip two frets towards the bridge to reach this B6. Keep the same two-fret distance between the index barre and the ring finger.
