Ethics of Collecting Dance

Hello folks, I have a concern about collecting dances. When I first began to consider calling contras, I video recorded several dances, mostly to observe and study the walk-thus. Since I have begun calling, I carry a memo pad in my pocket, and write down dances, or titles, that I find interesting. Many of these dances never make my active calling collection, but many do. I have always asked the callers/bands for permission to record, but I have not asked for permission to notate dances and titles. I really like calling dances that I have danced and enjoyed, and that is my reason for taking notes. I also have never copied another callers program, although I enjoy looking at them. When I ask a caller the name of a dance, most callers feel honored that I would want to call one of their choices. Occasionally the response is not so positive, and I am left feeling like a pick-pocket. Any thoughts on this to share? Rich Sbardella Stafford Springs, CT
