Range
C2 to C7765.4 Hz – 2.09 kHz
Five-octave instrument; 4, 4.3 and 4.5-octave instruments start at C3, A2, F2 (VSL).
| Low | C2–B2 | deep, long (2-3 s) |
|---|---|---|
| Middle | C3–B4 | warm, round |
| High | C5–C7 | short, woody |
Register split is an estimate; VSL only says the low and middle registers carry most of the writing.
Tuning: Bars tuned to equal temperament with overtones at about 4x and 10x.7
Overtones reach about 2.5 kHz (the highest harmonic within 40 dB of the strongest, at a moderate level; louder playing reaches higher).

The sound
The bars are thinned under the middle so the 2nd and 3rd modes sit at about 4x and 10x the fundamental (two octaves, and three octaves plus a major third); the tube resonators boost the fundamental.
Where the sound goes
A full-size marimba is about 2.5 m long and spans 3.5 to 5.5 octaves; sound comes from many points, because each bar has a tube resonator beneath it. Shure's stereo section names "marimba" (spelled "miramba") as an instrument big enough to deserve a stereo pair live.14,5
Playing techniques
- Mallets: soft yarn damps the upper partials (dark, round); hard mallets are brighter with more attack
- Rolls: tremolo to sustain a note
- Bowing: a double-bass bow on the bar, a sustained, ethereal tone7
How loud
Sound pressure level measurements as published. Different kinds of figure (a playing level, a peak, a dose at the player's ear) can't be compared with each other, and neither can figures at different distances.
| Peaks | |
|---|---|
| 117.8 dB | at the player's head position; Marimba (Marimba One, Ron Samuels), played by a percussion student in an individual practice session in a practice room of the F. Chopin Academy of Music, Warsaw; 1/4-in B&K 4135 mic on a tripod at the position of the musician's head; 120 s music selection12 |
| 137.6 dB(C) | personal dosimeter worn by the player; Marimba player, marching band rehearsal (same session)13 |
| Player's exposure (dosimeter) | |
| 105.6 dB | at the player's head position (tripod mic near the instrument); Marimba (Marimba One, Ron Samuels), played by a percussion student in an individual practice session in a practice room of the F. Chopin Academy of Music, Warsaw; 1/4-in B&K 4135 mic on a tripod at the position of the musician's head; 120 s music selection12 |
| 90.4 dB(A) | personal dosimeter worn by the player; Marimba player in a US high-school marching band (front ensemble), rehearsal of about 2.5 h on 5 Nov 201913 |
Measured at the player: 105.6 dB with peaks of 117.8 dB at the head of a student practising alone in a Warsaw practice room (Jaroszewski et al.), and 90.4 dB(A) dose-meter level with 137.6 dB(C) peak for a marching-band front-ensemble marimba player.
Recording it
Soft mallets give warmer tones, hard ones far more attack; it is "very easy to over-emphasise" the strike, so capture the whole instrument including the resonators. A forum poster found the bass "deafening" with a mic under the centre of the instrument; the replier blamed the room, since a marimba works with the room.14,15
Mics
- 8 setups from 6 sources, 5 of them independent of any mic maker.
- On top: the mics more than one source names for this instrument, in any role, the most named first. That is a count of sources, not our verdict.
- In the full list, each mic shows how many sources name it for that role, and how many of those come from a mic maker.
No mic is named by more than one source yet: each names its own.

High-quality condenser microphones are best because they capture the entire marimba as well as the space around the instrument.
