Stick Placement and Timpani Articulation
Semantics aside, the terms legato and staccato are generally used to describe opposite ends of the articulation spectrum for timpani sound. Every young timpanist is taught the concept of the legato and staccato stroke, the difference between a legato and staccato stick, and the effect that drum choice and head tension have on articulation and sustain. Placing pitches in different ranges of the drums can certainly help shape articulation because higher and lower head tensions respond differently. The mature player, however, learns to generate multiple articulations regardless of stick choice or the amount of tension placed on the head.
legato: in a smooth, flowing manner, without breaks between notes.
staccato: with each sound or note sharply detached or separated from the others.
What do these terms mean to the timpanist? How should the player interpret them? Can the timpanist go beyond stick choice, stroke, and head tension to accomplish the desired sound?
For quick hand-to-hand playing on the same drum, the timpanist has multiple methods available for creating the difference between a fast, articulate rhythm and a smooth, sustained roll. The usual approach is a combination of head tension, stick choice, grip, stroke, roll speed, and control of how long the stick remains in contact with the head. An additional option is stick separation: the distance between the two playing spots used by the hands. The mature player uses all of these variables together to achieve the desired effect. Many players, however, are less aware of how stick placement itself affects the sound output.
The finer points of articulation through head tension, grip, stroke, roll speed, stick contact, and other technical matters will be left for another discussion and to the informed judgment of the timpanist. This page focuses only on stick placement on the head and the physics of how that placement affects the sound.
Why Clearing Matters
When a timpano head is well-tempered, the player can strike the drum at multiple spots around the circumference of the head without generating a discernible pitch discrepancy. This gives the player a wider palette of tonal colors and more articulation options.
Stick separation only works musically when the head is clear enough for different playing spots to share the same principal tone. If one area of the head speaks sharp, flat, dull, or unstable, spreading the hands will expose the problem. A legato roll depends not only on smooth hands, but also on a membrane whose pitch center remains stable across the playing area.
When the head is well-tempered, the near-harmonic preferred modes are better aligned and easier for the ear to organize into a stable pitch center. When aligned properly, these preferred modes are what give the timpano its sense of pitch.
The preferred modes of an air-loaded vibrating membrane vibrate in alternating regions divided by nodal diameters, somewhat like pie-shaped sections: halves, quarters, sixths, eighths, tenths, twelfths, and so on. Beginning with the principal tone, mode (1,1), which we hear as the pitch of the drum, successive preferred modes can be added to the spectrum up to mode (6,1). The video below demonstrates this phenomenon.
All preferred modes in motion.
Preferred Modes (1,1) Through (6,1)
Center Stroke and Normal Playing Area
How these preferred modes are excited depends on where the head is struck. In an ideal circular membrane, a perfectly centered stroke strongly favors the inharmonic concentric modes and minimizes the preferred diametric modes. The energy from the concentric modes is radiated efficiently, which means the sound dies away relatively quickly when the drum is struck in the center.
Center Stroke: Inharmonic Concentric Modes
In order to excite the preferred modes, the player must strike in the normal playing area, in from the rim and away from the center. A single stroke can be visualized as sending energy across the head along a dominant diameter, but the actual sound is produced by the interaction of many membrane modes. The video below shows the path of a single strike at the normal playing spot in slow motion.
The preferred modes are less efficient at radiating their energy than the lowest center-active modes, so they decay more slowly. The longer this modal energy is sustained, the more the vibrating diametric modes can produce a sustained sense of pitch.

Close Stick Placement: A More Staccato Response
When repeated strokes occur at the same striking point in quick succession, such as fast repeated notes played in one spot, each new stroke interrupts the vibration left by the previous stroke. This prevents the full resonance of each stroke from developing, emphasizes the attack, and creates a more detached, staccato impression.
Together with a firmer grip, a more articulate stroke, and careful control of how long the stick remains in contact with the head, the timpanist can use close stick placement to create a more pointed and separated sound. The effect is not produced by placement alone, but placement is one important part of the articulation.
Separated Stick Placement: A More Legato Response
When the timpanist separates the hands for fast repeated strokes, such as in a roll, each stroke interrupts the previous vibration less directly. The two hands are still exciting the same membrane, but they are not repeatedly striking exactly the same point. This allows the resonance to connect more smoothly from stroke to stroke, creating a more legato impression.
Together with a relaxed grip, smooth stroke, appropriate roll speed, and controlled stick contact, the timpanist can use separated playing spots to produce a more sustained and connected sound. Some players advocate separating the hands by the distance of a “dollar bill,” roughly 6 to 7 inches. Others separate the hands much farther. There is no single rule. Both methods can work, provided the head is well-tempered and the pitch center remains stable across the playing area.
This is where the earlier clearing work becomes practical. A well-cleared head allows the player to move around the normal playing area without creating obvious pitch disagreement. A poorly cleared head may sound acceptable when both sticks remain close together, but spreading the hands can reveal local pitch zones, shimmer, or uneven tone. In that case, the problem is not simply the player’s roll technique; the membrane itself is not cooperating evenly.
A Visual Analogy for Stick Separation
The video below can help visualize what happens when the hands are separated. This is only an analogy, not a literal model of timpani membrane motion. When the grid appears, follow the three balls that traverse from the left to the right of the screen. Then focus on the outer two of the three balls, which represent the “dollar bill distance” philosophy. This gives a visual impression of how separated strokes may travel through the head without immediately interrupting one another in the same way as repeated strokes at one exact point.

Play the movie again and focus on the paths of the balls to either side of the two balls in the “dollar bill distance” example. The farther the balls are separated, the less immediate interruption occurs between their paths. In timpani terms, wider stick separation can reduce the sense that each stroke is cutting off the previous one. In some situations, the separated strokes may even reinforce the sense of resonance and continuity.
However, wider is not automatically better. When the sticks are separated too far, especially when they become diametrically opposed, the sound can again become unstable or disconnected. At that point the hands may be exciting areas of the membrane that do not support the same pitch center, especially if the head is not well-tempered. The result may be less legato rather than more.
Articulation Based on Modal Excitation
The player’s goal is not to memorize one correct stick distance. The goal is to understand how placement changes the way the membrane responds. Close placement can emphasize clarity, attack, and separation. Moderate separation can encourage continuity, sustain, and a smoother roll. Excessive separation can expose pitch instability or create a disconnected sound if the head is not clear.
Stick choice, grip, stroke, register, dynamic level, roll speed, room acoustics, and head condition all remain important. Stick placement does not replace those variables; it adds another layer of control. A mature timpanist learns to choose the placement that best supports the musical context and the actual behavior of the drum in front of them.
