2nd

In the second position because that's where the first finger is but it's best found by placing this important movable shape on the 5th fret with your little finger.

Again no 3rd note so it can be used for major or minor but look for a better option if you can find it.

Try using this one anytime you see a minor chord. Again there's no tonic but it's a good sounding chord and a handy moveable shape.

Move the Cm6 up 2 frets and you have a Dm6. Who'd have thought?

These chords really need all three notes but this is another easy moveable shape to grab and even without the tonic is one that you'll use a lot.

Another very useful moveable voicing this time the tritone has the 5 in the bass

A nice sounding voicing this one doesn't have the tonic either.

This D jaor doesn't have the tonic D in it but it does have the 3 and is a useful moveable shape.

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.
