If you've ever sat, listening back to a track you’ve just layed down in your DAW and wondered why your mix sounds muddy, harsh, or just a bit flat compared to your favourite tracks, the reason could be many things but often it comes down to EQ. Short for equalisation, EQ is one of the most powerful tools in music production. Get it right, and your song suddenly opens up - every instrument has its place, the bass feels tight, the vocals soar, and the whole mix breathes. Get it wrong, and no amount of fancy plugins or expensive gear will fix it.
But what exactly is EQ? And how can you use it to take your productions from "pretty good" to "that sounds incredible"? Let's dig in.
At its core, EQ is about shaping frequencies. Every sound you hear is made up of different frequencies, from deep sub-bass rumbles to sparkling highs. EQ lets you adjust these frequencies so that each part of your mix has space to shine.
Think of it like sculpting clay. You start with a block of sound, then carve away or add details until it takes the shape you want.
For example:
In short, EQ is your way of balancing, enhancing, and sometimes fixing the sound of your tracks.
Before diving into EQ adjustments, set yourself up for success:
Get your listening environment right:
Have reference tracks ready:
Start with quality recordings:
Not all EQs are built the same. Here are the main ones you'll encounter:
Parametric EQ - The go-to for most producers. It lets you select specific frequencies, adjust the gain (boost or cut), and control the "Q factor" (how narrow or wide the adjustment is). Your DAW's stock EQ is likely parametric and perfect for learning.
Graphic EQ - A row of fixed sliders across the frequency spectrum. Great for live sound or broad shaping.
Shelving EQ - Boosts or cuts everything above or below a set frequency. Perfect for taming low-end rumble or adding air to the top end.
Dynamic EQ - Like a hybrid between EQ and compression, it changes its effect depending on the input signal. Super useful for controlling harshness in vocals or resonant peaks in instruments.
A lot of EQ talk can get technical, but the basics are straightforward:
Subtractive EQ: Cutting out what you don't need. It's a cleaner way of making space in your mix and should be your first instinct when something sounds wrong.
Additive EQ: Boosting frequencies. While cutting is often cleaner, boosting is perfectly valid when used intentionally - for example, adding "air" to a vocal or giving a kick extra punch.
Instead of just lows, mids, and highs, here's a detailed breakdown of where things live:
This controls the "width" of your EQ move. A high Q means a very narrow, surgical cut or boost (great for removing a single resonant frequency). A low Q means a broad, gentle curve (better for musical shaping).
Rule of thumb: Use narrow Q for cutting problem frequencies, wider Q for musical shaping and boosts.
When you're starting out, follow this process:
Step 1: Clean up first
Step 2: Create space
Step 3: Enhance selectively
Here's where it all comes together. Some essential strategies you can start using straight away:
If your mix feels too boomy, instead of boosting highs, try gently cutting in the low-mids (say 250-400 Hz). It often clears things up more naturally.
Rolling off the low end on instruments that don't need it (like guitars or vocals) can clean up space for your kick and bass. But don't overdo it - if you set the filter too high, you'll thin out the warmth and body that makes a sound feel full.
Sweet spot: Try 80-100 Hz for most non-bass instruments, adjusting by ear.
If your vocal and guitar are clashing, cut some of the mids from the guitar around 2-4 kHz. This makes room for the vocal to shine without everything fighting for attention.
Soloing an instrument to EQ it can be useful, but always go back and check how it sits in the mix. What sounds "perfect" alone might not work with the rest of the track.
Pro tip: Solo to find problems, but make your final adjustments in context.
After making EQ changes, bypass the plugin and compare. Ask yourself: "Is this actually better, or just different?" If you can't tell, you probably don't need the EQ.
EQ plugins have great visuals, but they can trick you into "mixing with your eyes." Close your eyes, trust your ears, and make decisions based on what sounds right.
Here are starting points for common instruments. Remember: these are guidelines, not rules. Every recording is different.
Try cutting 200-400 Hz first, then add 3-5 kHz for presence. If it still needs more clarity, try a gentle boost around 8-10 kHz.
Start by high-passing non-bass instruments at 80-120 Hz. Then check for buildup in the 200-400 Hz range across multiple tracks and cut where needed.
Look for buildup around 2-4 kHz and 6-8 kHz. Use a spectrum analyser to spot peaks, then make narrow cuts of 2-3 dB to tame them.
Try boosting the kick around 60-80 Hz and cutting the bass at the same frequency. Then boost the bass around 100-120 Hz where the kick isn't sitting. This creates complementary space.
Here's a simple exercise to train your ears and discover problem frequencies:
This teaches you what different frequencies sound like and trains your ears to spot problems quickly.
While fundamentals remain the same, different genres emphasize different frequency ranges:
Hip-hop and electronic music: Heavy emphasis on sub-bass (20-60 Hz) and tight, punchy kicks. High-pass almost everything except kick and bass.
Rock and indie: Midrange-focused with guitars living in 400 Hz-2 kHz. Make space for vocals by cutting guitars in the 2-4 kHz range.
Jazz and acoustic: Preserve natural warmth and body. Use gentler EQ moves with wider Q values for musical shaping rather than surgical cuts.
Pop: Bright, clear vocals sitting prominently in 3-6 kHz. Clean low end with strong sub-bass when needed.
A few things to keep an eye on as you learn:
Over-boosting everything - Your mix will quickly turn harsh or messy. If you're boosting most tracks, try cutting instead or turning down your master fader.
Relying only on high-pass filters - Cleaning up is good, but don't strip the warmth out of instruments that need it.
Stacking EQs unnecessarily - Less is often more. If you need multiple EQs to fix one track, the problem might be the recording itself.
Forgetting the big picture - EQ is about balance, not making every sound massive. Sometimes the best EQ move is no EQ at all.
Extreme boosts or cuts - If you're boosting or cutting more than 6-8 dB, question whether you need a better sound source.
Not using reference tracks - Comparing your mix to professional releases keeps you grounded and prevents going too far in any direction.
Here's the truth: reading about EQ will only take you so far. The real magic happens when you practice - tweaking, listening, and training your ears to notice subtle changes.
As you develop your production skills, remember that great mixes start with great performances. When you're confident in your playing and timing - whether you're working with keyboards, drums, or other instruments - you'll find yourself reaching for EQ as an enhancement tool rather than a fix-it solution. Strong rhythmic accuracy and musical awareness mean you're making intentional creative choices with EQ rather than compensating for mistakes.
That's why building fundamental skills matters. The better your foundation in rhythm, timing, and musicality, the more intention you bring to every mix decision. Suddenly, EQ isn't just about fixing problems - it's about enhancing performances you feel confident in.
How much EQ is too much? If you're boosting or cutting more than 6-8 dB regularly, you might need a better recording or sound selection. Extreme EQ moves can introduce phase issues and make your mix sound unnatural.
Should I EQ every track in my mix? No. If a track sounds good in the mix without EQ, leave it alone. Not every sound needs adjustment. Some of the best mixes have tracks with no processing at all.
What order should I EQ things in? A common approach: start with drums and bass (the foundation), then vocals (the focal point), then everything else. However, there's no strict rule - work on whatever's causing the biggest problem first.
Should I use my DAW's stock EQ or buy plugins? Start with stock EQ. Modern DAWs have excellent EQ tools that professionals use every day. Learn the fundamentals first before investing in additional plugins.
How do I know if my EQ changes are actually better? Always use A/B testing - bypass your EQ and compare. If you can't clearly hear an improvement, you probably don't need that adjustment. Trust the process: better usually sounds obviously better.
EQ isn't just a technical tool - it's one of the most creative parts of producing music. It lets you shape emotions, highlight what matters, and bring clarity to your ideas. Master it, and your songs will sound polished, professional, and uniquely yours.
Start with the basics: cut before you boost, high-pass what doesn't need low end, and always EQ in context. Use the frequency sweep exercise to train your ears. Reference professional mixes. And most importantly, trust your ears over any visual display.
The journey from beginner to confident EQ user takes time, but every mix you work on builds your skills. Be patient with yourself, experiment freely, and remember: there are no absolute rules in music production, only guidelines and good taste.
Now go make something incredible.
