Some Moveable Chord Forms, PDF of chart of moveable chords. While most charts of moveable chords are based on the CAGFD system, this chord chart is based on which string the root note of the chord falls. This is so you can think about chords as root position, first inversion, or second inversion. The CAGFD system tends to emphasize chord melody playing and voice leading, while this approach tends to emphasize functional harmony. Both are perfectly valid ways of thinking about uke chords, but I put these chord charts online because I haven't really seen anyone else take this approach.
