EQ Frequency Chart: The Complete Guide by Instrument

TL;DR: Every instrument has a frequency range where it naturally lives: sub-bass and bass for low end, low-mids for body, mids and upper-mids for presence, and air for sparkle. The full chart is below. But memorizing ranges will not fix a bad mix on its own. Most frequency problems trace back to three habits: mixing on an untreated room or weak monitors, boosting before cutting, and soloing instruments instead of judging them inside the full mix. Fix those three habits and the chart becomes far more useful than it is on its own.

What frequency range does each instrument actually occupy? Sub-bass sits around 20 to 60 Hz, bass around 60 to 250 Hz, low-mids around 250 to 500 Hz, midrange around 500 Hz to 2 kHz, presence around 2 to 6 kHz, and air above 6 kHz. Every instrument overlaps several of these zones at once, which is exactly why a frequency chart is a starting point, not a formula. The full breakdown by instrument is below, along with the habits that cause most people to misuse it.

The Complete EQ Frequency Chart by Instrument

Here is the EQ frequency chart breakdown of where the most common sources in a mix actually sit across the spectrum. Use this as a map, not a rulebook; every room and every source shifts these ranges slightly.

Why an EQ Frequency Chart Alone Will Not Fix Your Mix

The single biggest cause of frequency problems has nothing to do with knowing the chart. It is poor acoustic treatment paired with a weak monitoring system. Without accurate monitoring, you cannot actually hear what your mix is doing, so you correct for problems that are not real and miss the ones that are.

This shows up in predictable ways. Harsh top end creeps in because you cannot hear how bright the mix already is. Vocals turn boomy because the low-mids are lying to you in an untreated room. Bass ends up excessive because you are mixing without a subwoofer and overcompensating for content you cannot actually feel. None of this is a chart problem. It is a monitoring problem wearing a frequency chart’s clothes.

Frequencies Fighting for the Same Space

Every mix has instruments competing for the same slice of spectrum, and that competition is not limited to frequency. It happens in the stereo field too. A bass guitar and a kick drum both want the same low end. A vocal and a guitar both want the same presence range.

When two sources fight for identical space, the fix is not always more EQ. Sometimes the real fix is panning, moving one source out of the center so it stops competing head-on with another that needs the same room to breathe.

Boost vs Cut: Why the Order Matters

I made this mistake myself when I was starting out: boosting before cutting. It feels productive, since you hear an immediate, exciting change. The problem is what it does to the rest of the mix.

Boosting first tends to build a mix that sounds boomy in the low end or thin once every track is competing for the same space. Cutting first clears room for a source before you decide it actually needs more of anything. Try removing what is fighting for space before you reach for a boost. More often than expected, the boost turns out to be unnecessary once the clutter is gone.

The Solo Button Trap

Another mistake I see constantly, especially from newer producers, is EQing an instrument in solo instead of inside the full mix. A track soloed in isolation almost never sounds like the same track sitting inside a dense arrangement. Frequencies that seem missing in solo are often already covered by another instrument in the full mix.

Frequencies that sound fine alone can clash the moment every other track joins in. Make every EQ decision with the whole mix playing. The chart tells you where an instrument generally lives; the full mix tells you what it actually needs right now.

Key Takeaways

• Every instrument has a natural frequency home, but overlap with other instruments is normal and expected.
• Poor acoustic treatment and weak monitoring cause more frequency mistakes than not knowing the chart.
• When two instruments fight for the same frequency range, panning can solve what EQ alone cannot.
• Cut before you boost; boosting first tends to build a boomy or thin mix.
• Always EQ inside the full mix, never in solo; context changes what a track actually needs.
