This short exercise is a good chop builder for keyboard percussion. It focuses on short spurts (which builds speed), and its length allows for numerous repetitions (which builds endurance). I came up with this exercise several years ago when I was trying to help a student build their two-mallet speed. I didn’t expect it to be so popular, but my students have enjoyed playing it ever since. It’s fairly catchy, and the simplicity of its structure makes it easy to learn. I have seen firsthand that the students who practice it regularly achieve good results.
When first learning this exercise, take it slowly until you can strike each note with 100% accuracy. It is short enough to memorize fairly easily. Remember that the key to speed is staying relaxed! Of course, you have to push your muscles in order to build endurance, but you must push them with good technique. Don’t let the speed create a sense of uncontrolled frenzy. Don’t lock your arms or wrists. Stay relaxed, yet keep your sound intensely focused. Strive for consistent strokes, so that you achieve clean execution and articulation.
Enjoy playing! I hope you notice significant improvement in your singles quality and speed.
