In Moeller technique, the hands use a wave-like motion. It is often compared to cracking a whip or snapping a towel. The key moment is lifting the back of the stick and bending the wrist during the preparation. The front end of the stick initially stays at the same height. Then the wrist opens in the opposite direction, lifting the stick while the hand itself moves down. Finally, the wrist brings the stick down to the drum and produces the stroke.
Depending on the dynamics required, Moeller technique can use a smaller or larger group of muscles: from wrist and part of the forearm to the full forearm and elbow. Sometimes even the shoulder is involved for the most powerful strokes.
The Moeller approach depends on smooth, measured motion. The hand and stick accelerate naturally without wasting energy during the stroke. Together with Gladstone technique, it is one of the keys to natural and organic movement in drumming.
