Choosing your constraints is an inherently creative decision, because it is foundational to all the other creative decisions you make.
There are no creative chords. There are creative chord progressions.
There are no creative chords. There are creative chord progressions.
Tell that to my friend's Bm7sus4add11/D# (I made that up but that's the sort of stuff he does until I say "can we please do something more normal")
OK so I am torturing the metaphor a little but what I mean is, a set of notes in a chord is not creative absent the context you're using it in (a progression, a key signature etc.)
It only really becomes a creative choice once somehow constrained. More or less just noise without it.
