Half-Forw The slanted bar contacts the high strings further from the nut with a slope of one half a fret per string. Forward The slanted bar contacts the high strings further from the nut with a slope of one fret per string. Dogleg The dogleg uses the end of a forward-slanted bar to contact the two high strings at the same fret.

Backward The slanted bar contacts the high strings closer to the nut with a slope of one fret per string. Allow pulls The left hand pulls the 1st or 2nd string sideways behind the bar, raising the pitch by one half-step. The diagram shows this as if the bar was bent. Left-hand All notes barred No open strings. 1 open high string Move the bar so it's only touching two of the strings being played, with a high string open. 1 open low string Move the bar so it's only touching two of the strings being played, with a low string open. 2 open strings Use the tip of the bar to touch only one of the strings being played. All open strings Don't use the bar at all to make the chord. Right-hand Adjacent strings Play the neighbor strings: 6,5,4 or 5,4,3 or 4,3,2 or 3,2,1. Skip 1 string Play strings 6,5,3 or 6,4,3 or 5,4,2 or 5,3,2 or 4,3,1 or 4,2,1. Skip 2 strings Play strings 6,5,2 or 6,4,2 or 6,3,2 or 5,4,1 or 5,3,1 or 5,2,1.

Bar Angles

Straight The bar contacts all the strings at the same fret.

Half-Forw The slanted bar contacts the high strings further from the nut with a slope of one half a fret per string.

Forward The slanted bar contacts the high strings further from the nut with a slope of one fret per string.

Dogleg The dogleg uses the end of a forward-slanted bar to contact the two high strings at the same fret.

Half-Back The slanted bar contacts the high strings closer to the nut with a slope of one half a fret per string.

Backward The slanted bar contacts the high strings closer to the nut with a slope of one fret per string.

Allow pulls The left hand pulls the 1st or 2nd string sideways behind the bar, raising the pitch by one half-step. The diagram shows this as if the bar was bent.

Left-hand

All notes barred No open strings.

1 open high string Move the bar so it's only touching two of the strings being played, with a high string open.

1 open low string Move the bar so it's only touching two of the strings being played, with a low string open.

2 open strings Use the tip of the bar to touch only one of the strings being played.

All open strings Don't use the bar at all to make the chord.

Right-hand

Adjacent strings Play the neighbor strings: 6,5,4 or 5,4,3 or 4,3,2 or 3,2,1.

Skip 1 string Play strings 6,5,3 or 6,4,3 or 5,4,2 or 5,3,2 or 4,3,1 or 4,2,1.

Skip 2 strings Play strings 6,5,2 or 6,4,2 or 6,3,2 or 5,4,1 or 5,3,1 or 5,2,1.

Skip 3 strings Play strings 6,5,1 or 6.4.1 or 6,3,1 ir 6,2,1.

Chords need >= 1 color note Only one "color" note is required
in each chord.

Chords need >= 2 color notes All "color" notes are required
in each chord.

Allow color notes low Normally "color" notes are restricted to the high 2 notes of the chord.

Avoid "jangling" This avoids chords wth notes 1/2 step or a whole step apart.
