By using this basic formula 1x2x3x4=24; we arrive at a finite number of 4-note chords, i.e. seventh chords (Root, 3rd, 5th,7th). A list of these chord voicings/permutations is given with some examples of how to practice them. Technically you'll find some that aren't suited to guitar, but I find them essential to filling in a complete picture of the fingerboard.
