Funny how things happen: Here I am in Alabama, enjoying all I'm learning about the Alabama Blues Project. Then I find that Kim Davis, the Programs & Office Assistant, just happens to teach Irish Dance. The juvenile I'm currently working on has a character who, in the 1870s, does an Irish jig and inspires a painting crucial to the story.
I have never seen an Irish Jig. Nor did I realize that a jig is a special style whose beat differentiates it from, say, a reel or hornpipe, rather than being a dance genre per se. Kim was able to point me to a video that shows step by step what an 8 hand jig would have looked and sounded like in the time of my story. She is also going to put me in contact with someone who can answer further research questions.
My story character eventually ends up in California, but for my research, I seem to be in "mother lode country" right here in Alabama.
