B

BAsed on the D major from the open position this one has no 3 so it's quality is ambiguous but if you're this far up the neck and need a B chord it's about your only option. It can be usaed for a major or a minor.

A moveable shape in the 4th position the tonic B is in the bass

Another great sound worth investigating

A great sounding voicing the the tonic in the bass and the tritone on top.

By moving the 5 note on the middle string up 2 frets you get the 6

This moveable shape becomes a bit easier to grab up in the fourth position

Based on the old barre chord this voicing is missing the 3rd so can also be used to replace a minor 7th chord. Without the third though you can't hear the tension in the tritone and so it doesn't really cut the mustard. It's a moveable shape though that is easy to grab so it's worth knowing for those times when you need a seventh chord for half a barre or so.
