Hi Callie. My post was (sort of) a joke. Someone mentioned a Bb9th chord, which is kinda jazzy. The song I was referring to (Nitelife) has a pattern that goes C, C9, F, Bb9..... I drop the high F (the fifth in a Bb) to an E (open string). To some that's more than "jazzy" it's downright disonent!

Sorcha. I want to marry you and have your children! You have so many wonderful bad habits.
