🎚️ Understanding Frequency Bands in Music
The human ear can generally hear sounds between 20 Hz (low) and 20,000 Hz (high).
These frequencies make up everything we hear — from deep bass to high-pitched whistles.
We can divide this range into three main bands:
| Frequency Band | Range | Also Called | Sounds Like |
|---|---|---|---|
| Low Frequencies | 20 Hz – 250 Hz | Bass | Deep, boomy (Kick drums, Bass) |
| Mid Frequencies | 250 Hz – 4000 Hz | Mids | Body and presence (Vocals, Chords) |
| High Frequencies | 4000 Hz – 20,000 Hz | Treble | Bright, sharp (Hi-hats, Sparkle) |
Standard (More Detailed) Breakdown:
| Range Name | Frequency Range | Common Sounds |
|---|---|---|
| Sub-bass | 20 – 60 Hz | Subwoofers, rumble, deep synths |
| Bass | 60 – 250 Hz | Kick, bass guitar, low-end body |
| Low Mids | 250 – 500 Hz | Warmth, muddiness in vocals/instruments |
| Midrange | 500 – 2,000 Hz (2 kHz) | Core vocal/instrument body, boxiness |
| Upper Mids | 2,000 – 4,000 Hz | Presence, attack of snare/guitar/vocals |
| Highs (Treble) | 4,000 – 20,000 Hz | Clarity, air, sparkle, cymbals, hi-hats |
🔊 How This Affects What You Hear
When you hear a sound, you’re actually hearing a mix of different frequencies playing at different volume levels (decibels).
If you change the volume of any frequency band using an equalizer (EQ), the sound will feel different. For example:
-
Boosting bass makes it sound deeper and heavier.
-
Cutting mids might make vocals sound distant.
-
Boosting highs adds brightness or sparkle.
