What are the choreographic strokes?

That doesn't sound right and there doesn't seem to be anything online about that topic, But if I had to assume, it probably means that it's a notation of a dance that involes with a 'stroke'. Perhaps goes on different levels in this dance and presents an interesting art form.

when you dance and are taught to use your body in a motion where you wisp yourself back and fourth

Explanation:

well seeing i am an artist and i actually did a self portrait; i will describe how i painted it.   i used acrylic on a stretch canvas about 4 feet wide by 6 feet tall. i painted myself smiling in a soft pink long dress, white tile floor sitting on a white couch with a table behind and a vase of gorgeous flowers.   i also had a round white hat with a soft pink ribbon through it laying on the floor and on the table behind me was a lit candle. i kept it simple but soft and romantic.
