As you have learned, once you know the formula for a chord, you can play the notes in any order, play them together or as an arpeggio or a random pattern, omit some of them, alter some of them, etc. You can also create your own chords by working out a formula even if you don't know any shapes for the chord. Just say you want to experiment with altering 13th chords. For a start you could alter the 5th, or the 9th, or both, giving you the 13b5b9 chord below, shown here with a voicing built from a root note.
