open

Don't forget the open chord

A good option for the important C7 chord in the open position. It's easy to grab, the tritone is intact and the 5 in the bass gives it a good bluesy sound.

Another popular voicing because the D is so important in the ksy of G and it's an easy one to grab. It can be played for a major or minor chord because it's neither without the 3.

The minor 7 works better than the straight minor in this position with the flat 7 helping to outline the chord.

The minor 6 with the 5 in the bass is a cool sound and may be a better option than the minor in the open position, especially in a minor blues. Give it a shot.

A minor chord but without the tonic to hang the 3 off it may not always sound like you want it to. Another easy one though and good for a moveable shape.

An important chord when playing a blues in G because the tritone defines the chord well, the 5 in the bass is a bonus and you can get away without the tonic.

A great sounding voicing if you're after this sound. 

No tonic in this one but it's easy to grab and creates a handy moveable shape. C is the IV chord in G so beginners particularly will appreciate the simplicity of this common chord.

Called an open position chord because of the 2nd string open D, this one won't work as a moveable shape but ticks all the boxes back here
