I just finished the introductory video tutorial above about sus4 chords. It shows me jamming on the keyboard over a Csus4 chord, and afterwards explaining how you can do the same by following a few simple musical ideas.

I am in the process of adding a lot of great information to this post soon. So be sure to check back soon.

Sus4 chords are amazing tools for pop musicians. Especially, because you can play 9 different pitches in the bass with any given bass note, creating really interesting sounding harmony.  To demonstrate this I created a chord table that shows all possible chords we get when we use different bass notes for Csus4.
