I'll give it a try, from my perspective. I've been playing what I would call, traditional Cajun French music for over 30 years. I had heard of Creole music, but I had never heard the music itself. And then one day (many years ago) , I met Ed and Danny Poullard in Galveston, Tx. Ed gave me one of their newly released C/D's, "Poullard, Poullard and Garnier". That recordiig had a mixture of old traditional Cajun songs and old Creole songs. They weren't labled as such, but I could tell the difference when I heard them. I will have say, that the difference is so subtle, that there almost isn't a difference. I would say that the Creole songs are simpler, or less complex ? More "stripped down". If that makes any since? But, because they are less complex, they tend to have this little "groove" to them, that is more felt than it is heard? This is true for both the waltzs and two steps. It could very well be because of the influence of Blues music in the Creole music. Blues is layed back, smooth and flowing. That's my take on it anyway. BTW, that meeting with Ed and Danny was the beginning of a lifelong friendship and one of the greatest blessings in my life.

Joe Hall made a instruction DVD.
Maybe that's an option to look at
