The widest vocal range refers to the largest number of octaves a singer can phonate—from their lowest note to their highest. While most trained vocalists use 2–4 octaves, a handful of rare singers have achieved 6, 7, 8, and even 10-octave ranges, spanning frequencies that stretch the limits of human vocal physiology.
This guide explains who has the widest vocal range ever recorded, provides verified singer rankings, breaks down how vocal range is measured, and explores the science behind extreme vocal spans.

What Is the Widest Vocal Range?
A singer’s vocal range is measured from the lowest note they can phonate to the highest note they can produce.
The widest vocal range involves:
- A very low limit (often subharmonic or basso profundo territory), and
- A very high limit (typically whistle register).
Most singers have 1.5–3 octaves.
Elite singers may reach 4–6 octaves.
Only a few documented individuals exceed 8+ octaves.
How Vocal Range Is Measured (Octaves + Notes + Hz)
Vocal range is calculated by:
- Identifying the singer’s lowest controlled note
- Identifying the highest stable note
- Counting the octaves between them
Example:
From E2 (82 Hz) to E7 (2637 Hz) = 5 octaves
Vocal registers involved:
- Chest voice
- Head voice
- Falsetto
- Whistle register
- Subharmonics (for extreme lows)
Widest Vocal Range Ever Recorded (World Records)
1. Tim Storms – 10 Octaves (Verified Record Holder)
- Range extends down to G−7 (0.189 Hz)
- Highest notes reach G10
- Holds multiple Guinness World Records
- Achieves extreme lows via subharmonic vibration, a rare trait
2. Georgia Brown – Claimed 8 Octaves
- Noted for whistle register peaks as high as G10 (debated scientifically)
- Often reported as one of the highest female ranges
3. Dimash Kudaibergen – 6+ Octaves (Widely Verified in Performances)
- Can produce high soprano-like tones and deep baritone notes
- Noted for incredible agility across registers
These ranges combine physiological uniqueness, technique, and register control.
Top Singers With the Widest Vocal Ranges (Verified List)
| Singer | Approx. Vocal Range | Notable Traits |
|---|---|---|
| Tim Storms | ~10 octaves | Lowest human notes ever recorded |
| Georgia Brown | ~8 octaves (claimed) | Extreme whistle register reaching C9–G10 |
| Dimash Kudaibergen | 6+ octaves | Operatic + pop agility |
| Axl Rose | ~5 octaves | High belts + growls |
| Mariah Carey | ~5 octaves | Legendary whistle tones |
| Vitas | ~4.5–5 octaves | Piercing high male notes |
Competitor lists often mix verified data with myths; the above is based on documented ranges, recordings, and acoustical measurements.
Male Singers With the Widest Vocal Ranges
Men achieve wide ranges through:
- Falsetto
- Reinforced head voice
- Subharmonic techniques
Notable examples:
- Tim Storms – world record
- Dimash – extreme flexibility
- Axl Rose – eclectic rock range
- Vitas – rare male high register
Male wide-range singers tend to rely heavily on head voice, falsetto, and sometimes whistle.
Female Singers With the Widest Vocal Ranges
Women often excel in:
- Whistle register
- Advanced head-voice resonance
- Vocal agility
Notable examples:
- Mariah Carey – iconic for whistle up to G#7
- Georgia Brown – extremely high whistle claims
- Ariana Grande – E7-capable singer with agile upper register
Female high-range singers often exhibit:
- Slimmer vocal folds
- Efficient breath management
- Highly developed resonance strategies
Highest Notes vs Widest Range: Why They’re Not the Same
A singer can:
- Hit a very high note
- Hit a very low note
- But not necessarily both, meaning their range span may still be small.
Example:
- A soprano may hit C7, but cannot reach below C4 → small overall range
- A bass may sing C1, but never reach C6 → wide low range only
Widest vocal range = high + low extremes together.
Frequency Chart for Wide-Range Singers (Hz)
| Note | Frequency | Context |
|---|---|---|
| C1 | 32.70 Hz | Deep bass singing |
| E2 | 82.41 Hz | Standard male low |
| C5 | 523.25 Hz | High male/female head voice |
| C6 | 1046.50 Hz | Operatic soprano high |
| C7 | 2093 Hz | Whistle register |
| G10 | ~25,000 Hz | Extreme claimed notes |
A wide-range singer may span >20,000 Hz of frequency between low and high.
How Humans Achieve Extremely Wide Ranges
1. Register Stacking
A wide range requires mastery of:
- Chest voice
- Head voice
- Falsetto
- Whistle register
- Subharmonic register
2. Laryngeal Adjustments
Tilt, raise, or lower the larynx to change pitch and resonance.
3. Vocal Fold Manipulation
High notes require thin, fast vibration.
Low notes require thick, slow vibration—sometimes in fractional oscillations.
4. Resonance Tuning
Small mouth shapes help with highs; wide-open shapes assist lows.
5. Genetic Factors
Some people naturally possess:
- Longer or thicker vocal folds (low capability)
- Greater neuromuscular coordination (high capability)
Can You Train for a Wider Vocal Range?
Yes, but not infinitely.
Trainable aspects:
- Strengthening head voice
- Developing chest-to-head transitions
- Breath management
- Whistle register technique
- Low-resonance optimization
Not trainable:
- Vocal fold length/thickness
- Basic laryngeal structure
- Genetic resonance differences
Realistic potential:
Most people can expand 1–1.5 octaves with proper training.
FAQs
Who has the widest vocal range ever recorded?
Tim Storms, with a verified 10-octave range.
What singer can sing the most octaves?
Tim Storms (verified), Georgia Brown (claimed), Dimash (widely documented live).
How many octaves can humans sing?
Average: 2
Trained: 3–4
Exceptional: 5–6
World record: 10
Can women have wider ranges than men?
Women tend to have higher ceilings; men may achieve lower floors.
Either gender can achieve extreme spans.
Is whistle register required for a wide range?
For women—often yes.
For men—usually needed unless extremely strong subharmonics exist.
The widest vocal ranges combine rare physiology, advanced vocal technique, and exceptional register control, allowing singers to traverse notes from deep subharmonics to extreme whistle tones. While most humans never exceed 2–3 octaves, a few extraordinary vocalists have achieved ranges spanning 6–10 octaves, pushing the boundaries of what the human voice can accomplish.
