Chassé
A jazz lesson on the chassé, which means chased: one foot slides out and the other chases it, replacing it in the same spot.
A low chassé keeps the knees bent and stays at one level. A high chassé glides out, hops straight up with the legs coming together, then slides out again on the same leading foot. Use it to travel or to link one step to the next.
In this clip it is practiced to the right, then to the left, with a drag, replace and close on the way back.
