There are so many forms of dance. Some are free form and fluid and others more rigid.
Irish step dancing is all in the feet. It's quick moving, and it can be loud and solid, and very very exact.
As a drummer, the step dancer is my friend. We understand each other, we know that the rhythms we produce are at the heart of all we do. It is an extension of our heart beat and soul.
So listen closely to the rhythm, applaud it when it's loud and sharp and quick and lively and wonderful. Breathe in the rhythm and hold it tight.
