Watch the A Minor Chord Inversions online guitar lesson by Frank Vignola from Inversion Excursion
Now it's time to practice these inversions with a jam track. Start by strumming 4 or 8 beats per inversion moving to each inversion in a smooth and effortless manner. When learning something new, we tend to tighten up putting way too much pressure on the guitar neck which in turn makes it harder to play smoothly. Relax while making the move in between inversions and concentrate on trying not to squeeze the guitar neck too hard.
Lower register inversions are great because they usually are out of the way of soloists and vocalists. Soloists and vocalists are usually in the higher register of the Grand Staff so it is a good idea to play in a lower register while accompanying.
Arpeggio style playing is not only good for an exercise but as a great rhythm guitar part ala the Police guitar part sound. Also don't forget about the half step above slide down into the chord. Try out those effects as well with these lower inversions.
