Mary_J0, I'm so glad you're back. What you have selected is an indication of your exquisite taste.
A person who is "Jazzy" is synonymous with jazzy music; the way they walk, talk, and dress with a "jazzy" style makes that person jazzy.
Strange as it may sound, people who "try" to be jazzy won't succeed; that's because it comes from a feeling within that flows out.
I had a friend, who happened to be a professional musician, and he fit the description of a jazzy person. He woke up that way, he went to sleep that way, he dressed, walked and talked that way without even knowing it.
I guess it comes from being around jazzy people all the time. I think one can evolve into being a jazzy person, but it doesn't come overnight. Too much effort at being jazzy would come off as phony. Being jazzy must come from within.
I've been listening to Gregory Porter while writing this, and there's a good chance I'll buy that album, "Gregory Porter Greatest Hits".
