Watch the G Turnarounds: 1 online guitar lesson by Muriel Anderson from 1-2-3 Fingerstyle Guitar

The circle of 5ths can be used in any key to create a turn-around. Making each one a 7th chord leads to the next 7th chord until you get to your target chord.

Try different fingerings and positions of the chords. (See the book "All Chords in All Positions" for theory and exercises on finding chords in different positions.)
