Take any chord sequence you like, a song of yours, a standard, whatever. Now play that sequence using the 7th chords we learned and their inversions. Again, try to play the next chord using the inversion closest to the one being played.
I took a standard major II V I progression and played it using the 7th chord inversions. In D major this will look like this:
|Major II V I progression using 7th chord inversions on strings 2, 3, 4 and 5 in D major (click to enlarge).|
After you are comfortable playing your chord progression using the 7th chord inversions, try playing improvised lines using only chord tones.
In the above example you would play just chord tones of the II chord over the II chord, play just tones from the V chord over the V chord, etc...
I added an example of a short line played using only chord tones and very few passing tones (2 or 3). The line uses the exact fingerings you can see above. You will notice that, because I am only playing chord tones, the chords are quite evident even though there's no accompaniment.
