Up and Down Strokes allow drummers to play dynamically by combining soft notes and loud notes in any sequence. The key concept here is that height equals volume. Therefore a note played from a low height is quiet and one played from high is loud. The difficulty is in combining these two different approaches simultaneously. In this video I outline the technique whereby we play a quiet note low as we lift the stick high to follow with a loud note. This technique is also called the Moeller Technique after Sanford Moeller who described the method after observing drummers who had fought in the American Civil War in the 19th century. As with any new concept be sure to practice it slowly and deliberately so as to avoid bad habits.
