Instrument Frequency Chart — The Complete EQ Guide for Beginner Engineers
If you’re just starting out recording and mixing, this frequency chart is one of those things worth keeping within reach — right up until you know it by heart. It’s a genuine must-have for any beginner engineer: it shows you where each instrument “lives” in the spectrum before you even touch an EQ.
Why every engineer needs a frequency chart
Knowing these ranges gives you two concrete skills you can’t mix confidently without.
First — cleaning up a single instrument. Every signal carries frequencies the listener will never perceive as useful: sub-sonic rumble below the fundamental, buildup in the 200–500 Hz “mud” zone, or pointless fizz on a distorted guitar above 8 kHz. Once you know where those bands sit for a given instrument, you cut them on purpose instead of hunting blindly with an EQ.
Second — fitting instruments together in the mix. This matters even more than cleanup. Kick and bass fight over the same 60–200 Hz territory. Vocals and rhythm guitar collide around 2–4 kHz, where both sources carry their presence. Once you know where these collision points are, you can make room for one instrument at the expense of another — instead of boosting everyone’s presence and ending up with a harsh, fatiguing mix where nothing actually cuts through.
How to actually use this chart
Don’t treat these ranges as fixed EQ settings — they’re starting points, not presets. The real values shift with the instrument’s tuning, the mic, the genre, and whatever else is already playing in the mix. The chart has one job: cut down the time you spend hunting for a problem by ear with a high-Q sweep.
In practice, it plays out like this: start with a high-pass filter where the chart suggests one — it cleans up the low end of the mix without stripping the instrument’s character. Then check the “mud” zone for each source individually — you rarely need to cut it everywhere, usually just wherever a given instrument doesn’t actually need that band. Finally, look at presence conflicts (2–5 kHz) and decide which of two competing instruments gets to keep that band.
Key terms you need to know
| Term | Meaning |
|---|---|
| Rumble / sub-rumble | Inaudible or non-musical low-frequency content below an instrument’s fundamental — usually removed with a high-pass filter |
| Fundamental / Body | The core low-frequency resonance that gives an instrument its perceived size and weight |
| Mud / Boxiness | The 200–500 Hz region where low-mid buildup from multiple sources creates a cluttered, undefined mix |
| Presence | The upper-midrange band (roughly 2–5 kHz) responsible for clarity, articulation, and “cut-through” on small speakers |
| Air / Brilliance | The extreme high end (8 kHz and up), adding sheen, sparkle, or a sense of openness |
| Sibilance | Harsh high-frequency energy on vocal “s”/”sh” sounds (typically 5–9 kHz), controlled with de-essing |
Instrument frequency chart — the full breakdown
| Instrument | High-pass / cut zone | Body / Fundamental | Mud (watch out) | Presence / Attack | Air / Top-end | Note |
|---|---|---|---|---|---|---|
| Kick drum | below 30–40 Hz | 60–100 Hz (punch) | 250–400 Hz (boxy) | 2–5 kHz (beater click) | above 8 kHz — negligible | Sub and click are effectively two separate elements in one track |
| Snare | below 80 Hz | 100–250 Hz | 300–500 Hz | 2–5 kHz (crack) | 8–12 kHz (wire sizzle) | Top-end shimmer comes mostly from the snare wires |
| Hi-hats / cymbals | below 200 Hz (aggressive) | negligible | 300–500 Hz (bleed) | — | 8–16 kHz (shimmer) | Nearly all useful information sits in the top end |
| Toms | below 60–80 Hz | 80–200 Hz | 300–500 Hz | 3–6 kHz | little above 10 kHz | Body shifts up/down with tom size |
| Bass guitar | below 40 Hz (rarely useful) | 60–200 Hz | 250–500 Hz (clash with guitars) | 700 Hz–1.5 kHz (growl), 2–4 kHz (pick attack) | above 6–8 kHz — harmonics only | This is the fundamental of the notes, not the instrument itself |
| Electric guitar | below 80–100 Hz | 100–250 Hz | 300–500 Hz (esp. with distortion) | 2–4 kHz (bite/cut-through) | 6–10 kHz — often just fizz | On distorted tones, content above 8 kHz is often pure fizz — safe to cut |
| Keys / acoustic piano | below 60 Hz | 100–300 Hz | 300–600 Hz | 2–5 kHz (hammer attack) | up to 12–15 kHz — real harmonic content | Top end is genuinely musical here — less to cut than on guitars |
| Pads / synths | context-dependent | context-dependent | — | — | — | Sub content below 40 Hz usually just masks the bass — cut unless it IS the bass element |
| Male vocal | below 80–100 Hz | 100–300 Hz (chest resonance) | 300–500 Hz (classic “muddy” zone) | 2–4 kHz (intelligibility) | 5–8 kHz sibilance, 10–15 kHz air | Boominess is usually a proximity-effect issue at the mic |
| Female vocal | below 100–150 Hz | 150–500 Hz (higher than male) | 400–600 Hz | 3–5 kHz | 6–9 kHz sibilance, 10–16 kHz air | High-pass tends to sit more aggressive than on male vocals |
| Acoustic guitar | below 80 Hz | 80–200 Hz (body resonance/boom) | 200–400 Hz | 2–5 kHz (string definition) | 8–12 kHz (fret/string shimmer) | Body resonance easily tips into boominess — keep it controlled |
The rule beginners forget most
The main battleground is always 250–500 Hz. Carve mud out of the instruments that don’t need it there, rather than boosting everyone’s presence to compete for attention. That one rule cleans up more mixes than any EQ preset ever will.
Frequently asked questions
- Are these frequency ranges universal for every recording?
- No. They’re starting points built from years of studio practice, not fixed rules. Instrument tuning, mic choice, arrangement, and genre all shift the real numbers — your ears make the final call, not the chart.
- Where should a beginner start learning EQ?
- Start by training your ear to recognize the zones in this chart — rumble, mud, presence, and sibilance. Specific plugin settings only make sense once you can hear the problem yourself.
- What’s the difference between “mud” and “boominess”?
- Mud is buildup in the 200–500 Hz zone where too many instruments overlap at once. Boominess is usually a single-source problem — most often a proximity-effect issue at the mic during recording.
- Is a frequency chart useful during recording, or only at the mixing stage?
- Very much during recording too. Choosing mic placement, instrument, or strings with an eye on where the fundamental and presence will sit saves hours of corrective EQ later at mixdown.
