If we take the 4 notes in their 4 possible combinations we get (someone please correct this if I’ve made any mistakes) :
A, C, G, D = R, b3, b7,11 or sus 4 = Am7/11
C, G, D, A = R, 5, 9, 6 = C add 6/9 (no 3rd)
G, D, A, C = R, 5, 9, 11 or sus 4 = G add 9/11 (no 3rd) or G add 9 sus4
D, A, C, G = R, 5, b7, 11 or sus 4 = D7 sus 4
I wonder how these chords played as a progression might affect our DNA...
