Start practicing grabbing chord shapes in the air. I used to practice changing chords by fingering them on the back of my right arm. I would just practice remembering the chord form, placing it on my arm and then changing to another chord. I kept this up and the end result was that I learned how to grab those chords in the air and land on the strings in one movement. I finally got to where I could grab all the chords by just thinking "d" and going to it. Then think another chord and another. I did this when I was watching tv or when there was slow times at work. You can do this any where any time and it really helped me!

Learning how to form the chords all at once in the air and land on the neck ready to play the chord was critical for my learning process. That process started when I 1. learned to the shapes in my head, 2. then in my hand and 3. when I could grab any chord at once. This made quick changes possible.
