What is a Dance Step Sequence?
At the end of some of the freestyles, it says Dance Step Sequence.
What is it?
A dance step sequence is exactly what it sounds like. It’s a bunch of pre-specified moves and turns that you have to perform in a certain order in order to pass the freestyle level. As you get better, the dance step gets harder, and you learn more turns. The goal of the dance step sequence is to help you gain more control over your edges and your skating.
For example, in freestyle four, you learn backward inside and outside three turns. These are part of a serpentine ("S" shape) dance step that consists of three turn/mohawk combinations.
You are graded on how much control you have, and how big you make the turns. Of course, if you’re on a wrong edge in the dance step, you get taken off.
Then in FS5, you learn lots of fun things, like brackets. These are also in the dance step.
Basically, they are the ISI equivalent of moves in the field, testing your ability to control yourself.
I hope this helped!
