ed between the flesh of the palm at the base of the thumb and the tip of the middle finger. Interval changes are accomplished by moving the inside and outside mallets independently of one another, as described in Stevens' book,
Method of Movement for Marimba. As the interval widens, the inside mallet rolls between the thumb and index finger such that the index finger moves from underneath to the side of the shaft, and the middle finger becomes the fulcrum of the cantilever. The outside mallet is moved principally with the pinky and ring fingers, although the first section of the middle finger follows along and remains in light contact. When properly used, this grip causes no tension on the hand muscles.
The essential strokes
The
piston stroke is an essential component of Stevens technique. With this stroke, the mallets start in the up position, strike the bars, then return to the up position. The mallets are propelled completely by the wrist, and there is no prep stroke. When changing notes, the piston stroke is modified so that it starts above the first note and ends above the second note, ready to strike.
Strokes are further divided into four categories of motion.
Single Independent strokes involve moving the inside or outside mallets singly, pivoting around the shaft of the unused mallet.
Single Alternating strokes are used in single note patterns to be played by the same hand, alternating the inside and outside mallets.
Double Vertical strokes are used in playing double notes simultaneously by the same hand.
Double Lateral strokes are used for fast, rhythmically adjacent notes to be played by the same hand.
This method of striking the bars is designed for accuracy and momentum efficiency, since it attempts to eliminate all wasted motion. The piston stroke consolidates the preparation for each stroke into the recovery of the previous stroke.
Stevens v. crossed-style
There are three main grips used by mallet players: traditional crossed, Burton (which is a variation of traditional crossed) and Stevens-Musser. The traditional crossed grip is used almost solely by

players, thus making them the two most popular 4-mallet grips for percussionists in USA.
There are advantages as well as disadvantages to both crossed-style (traditional and Burton) and Stevens-Musser. Crossed-style grips make learning basic mallet control easy - and feel very stable. However, the interval can't be made as wide as with the Stevens grip and some say that rolls can't be made as well. With the Stevens grip, the mallets are more free to move independently than in crossed-style grips, so it is possible to make much more subtle motions, ultimately resulting in a greater range of motion and mallet control. But despite these advantages of the Stevens grip, it is harder to master than crossed-style grips. Additionally, though the Stevens grip is intended to place minimal tension on the hand muscles, the mallets exert greater leverage when they are in motion (since they are held at the very ends), requiring greater muscle control than with crossed-style grips. People with arthritis or similar conditions may not be able to use the Stevens-Musser grip.
As both grips carry advantages and disadvantages, the question of how to hold the mallets is up to what the player feels most comfortable with. Players should at least become familiar with the basics of both grips, so as to be able to choose the grip that best fits their style of playing.
