Two blog posts about how to go about creating choreography (especially if you are considering trying it for the first time - hint, hint!).
The first deals with things to consider and steps to follow, really helpful if you are new to it. http://www.anankedance.com/how-to-courageously-create-belly-dance-choreography/
The second talks about how we get stuck in choreography "formulas" of what a dance piece "should" look like http://bdpaladin.com/
I'm already reserving dance slots for the December show, so if you want one, let me know!
