The Velocity and Buck Exercises describe and break down the motions involved in velocity strokes (which are allowed to rebound back to their attack height) and cushion strokes (which are not allowed to rebound, or which are only permitted to rebound to a lower height than their attack). This exercise, along with The Fulcrum Exercise and The Hot Stove Exercise, enable you to truly isolate and perfect the building blocks of drumming fundamentals, as described by The Technique Triangle.
