Tim Storms holds the Guinness World Record for the widest vocal range. Guinness recognizes his range as 10 octaves, extending from approximately 0.7973 Hz to 807.3 Hz. The American singer achieved the record in Branson, Missouri, on August 1, 2008.
Georgia Brown holds the Guinness record for the widest female vocal range, covering eight octaves from G2 to G10.
These are extraordinary measured achievements, but they should not be compared directly with estimates based on notes found in songs. Laboratory measurements, live performances and commercial recordings can use different standards for deciding which sounds count as part of a singer’s range.
Regular voice range testing can help you track changes in your singing range over time.
Who Holds the Widest Vocal-Range Record?
According to Guinness World Records, Tim Storms produced frequencies from 0.7973 Hz to 807.3 Hz. Guinness describes this span as approximately G/G♯−5 to G/G♯5 and recognizes the frequency ratio as 10 octaves.
Because the measured pitches fall between G and G-sharp, Guinness notes that the interval is approximately nine octaves and 11 semitones when expressed in concert-pitch terms. The organization nevertheless recognizes the achievement as a complete 10-octave range based on its frequency measurements.
Storms’ lowest record-range frequencies are infrasonic, meaning they fall below the approximately 20 Hz lower boundary commonly associated with human hearing. These vibrations require equipment to measure and cannot be experienced like an ordinary sung note.
This distinction is essential. A measured vocal vibration does not necessarily have the volume, clarity, stability or tone needed for a musical performance. The complete analysis of Tim Storms’ vocal range explains how his record-setting low frequencies differ from conventional singing notes.
Widest Male and Female Vocal-Range Records
The current Guinness pages identify separate male and female record holders.
| Record | Singer | Recognized span | Reported boundaries | Verification |
|---|---|---|---|---|
| Widest overall and male vocal range | Tim Storms | 10 octaves | 0.7973–807.3 Hz | August 1, 2008 |
| Widest female vocal range | Georgia Brown | 8 octaves | G2–G10 | August 18, 2004 |
Guinness World Records states that Georgia Brown’s eight-octave range was verified by music experts using a piano, violin and Hammond organ in São Paulo, Brazil.
Under A4 = 440 Hz tuning, G2 is approximately 98 Hz and G10 is approximately 25,088 Hz. The upper frequency is above the commonly cited 20 kHz limit of human hearing, making it primarily a measured acoustic achievement rather than an ordinarily perceived musical pitch.
These records can change if Guinness verifies a successful new attempt. They should therefore be attributed to the organization rather than presented as permanent biological limits.
How Is Vocal Range Measured?
Vocal range is the interval between the lowest and highest pitches a person can produce under a defined set of conditions. In ordinary singing, the notes are usually identified with a piano, pitch detector or frequency-analysis tool.
The number of octaves between two frequencies can be calculated with this formula:
Each doubling of frequency equals one octave. For example:
- 100 Hz to 200 Hz = one octave
- 100 Hz to 400 Hz = two octaves
- 100 Hz to 800 Hz = three octaves
A complete measurement should record more than two note names. It should also document:
- Lowest stable frequency
- Highest stable frequency
- Tuning reference
- Register used for each note
- Note duration and stability
- Recording or testing conditions
- Whether non-musical sounds were accepted
- Whether the result was independently verified
Without this information, two singer-range claims may look comparable even though they were measured differently.
Why Singer Vocal Ranges Are Difficult to Compare
Online lists frequently mix several kinds of evidence:
- Controlled measurements: Frequencies are captured under defined conditions and independently verified.
- Live-performance notes: Researchers identify pitches from concert recordings, which may vary in audio quality.
- Commercially released recordings: The highest and lowest notes are collected from studio songs.
- Singer or fan claims: Range boundaries are reported without publicly available testing evidence.
Studio recordings can also involve pitch correction, layered vocals, altered playback speeds and other production techniques. A singer may reach a note during an unusual sound effect that they would not use in a normal melody.
Different researchers may also disagree about whether to include:
- Vocal fry
- Growls and screams
- Subharmonics
- Falsetto
- Flageolet sounds
- Whistle register
- Brief or unstable pitches
- Background vocals
- Spoken sounds
A responsible comparison should identify the evidence behind the number instead of presenting every online estimate as an official record.
Singers Known for Exceptionally Wide Vocal Ranges
Several performers are frequently discussed for their ability to move between unusually low and high registers.
| Singer | Why the singer is notable | Evidence category |
|---|---|---|
| Tim Storms | Guinness recognizes a 10-octave range | Official verified record |
| Georgia Brown | Guinness recognizes an eight-octave female range | Official verified record |
| Dimash Qudaibergen | Uses low notes, upper belts, head voice and whistle-like coordination | Performance-based estimates |
| Mike Patton | Recording surveys have identified an unusually large span across multiple projects | Recording-based estimates |
| Mariah Carey | Known for combining a substantial lower range with whistle-register notes | Documented recordings and performances |
| Vitas | Known for exceptionally high head-voice and whistle-like sounds | Performance-based estimates |
| Adam Lopez | Former holder of a Guinness record for an exceptionally high male note | Verified high-note achievement |
| Axl Rose | Recording analyses identify both very low and very high pitches | Recording-based estimates |
Estimates of Dimash’s vocal range differ because analysts do not always examine the same performances or include the same vocal effects.
Similarly, surveys of Mike Patton’s recorded vocal range may count notes from several bands, experimental recordings and unconventional vocal sounds. Such surveys can describe versatility, but they are not equivalent to a controlled Guinness test.
Mariah Carey is often described as having approximately five octaves, largely because she combines low notes with famous whistle-register pitches. She does not, however, hold the current overall Guinness record for widest range.
Does Whistle Register Count as Vocal Range?
Whistle register can count when the goal is to measure every stable pitch a person can phonate. It produces some of the highest frequencies available to the human voice and contributes substantially to the ranges reported for singers such as Georgia Brown and Mariah Carey.
Whether it should be included depends on the purpose of the measurement.
For a total phonational range, whistle notes may be appropriate. For a usable singing range, the evaluator may require the note to be controlled, repeatable and musically applicable. For a classical voice classification, an isolated whistle note usually says little about whether someone is a soprano, mezzo-soprano, tenor or another voice type.
Whistle notes can therefore be part of a singer’s total range without being part of their normal tessitura.
Do Vocal Fry and Subharmonics Count?
Vocal fry consists of slow, irregular vocal-fold pulses that can produce pitches below a singer’s normal modal register. Subharmonic techniques can generate frequencies below the fundamental pitch ordinarily associated with the vocal-fold vibration pattern.
These sounds may count in record attempts or explorations of total phonational capacity. However, they are not always suitable for melodic singing, and they should not automatically be counted when identifying a practical performance range.
A transparent range claim should state whether its lowest boundary was produced in:
- Modal or chest voice
- Vocal fry
- A subharmonic register
- Growl or another extended technique
The distinction also explains why the person who produces the lowest vocal notes does not necessarily have the lowest comfortable singing tessitura.
Widest Range vs Highest and Lowest Notes
The widest vocal range, highest vocal note and lowest vocal note are three separate achievements.
- Widest range: Greatest interval between the lowest and highest frequencies
- Highest note: Greatest frequency reached
- Lowest note: Smallest frequency reached
A singer could possess the highest known note without having the widest overall span. Another singer could establish an extremely low record but have a comparatively ordinary upper limit.
When comparing the highest vocal notes, the important figure is the upper frequency—not the total number of octaves between two boundaries.
Total Vocal Range vs Usable Range and Tessitura
A singer may have three different range measurements:
| Measurement | Meaning |
|---|---|
| Total phonational range | Every measurable pitch or vocal effect the person can produce |
| Usable singing range | Notes the singer can control with adequate tone, volume and accuracy |
| Tessitura | The area where the voice performs most comfortably over sustained music |
Record attempts usually emphasize total span. Music depends more heavily on usable range and tessitura.
A single extreme note may be impressive, but it does not show whether the singer can:
- Sustain a melody around that pitch
- Produce clear words
- Control volume and tone
- Repeat the note reliably
- Move smoothly into and out of it
- Perform it without excessive effort
This is why an artist with a controlled two- or three-octave singing range can be more versatile in real repertoire than someone with additional but unstable extremes.
Does a Wider Range Make Someone a Better Singer?
No. Range is only one aspect of singing ability.
Strong singing also depends on:
- Pitch accuracy
- Rhythm
- Tone
- Breath coordination
- Register balance
- Dynamic control
- Diction
- Stamina
- Musical expression
- Stylistic understanding
An extremely wide range can create more repertoire options, but only when the notes are coordinated and musically usable. A singer does not need five, eight or 10 octaves to perform demanding music successfully.
If your measured span approaches five octaves, this guide explains whether a five-octave range is good and how to evaluate the quality of those notes.
How to Measure Your Own Vocal Range
Warm up before testing and use a piano, keyboard or reliable pitch-detection tool.
- Begin near the center of your comfortable speaking and singing range.
- Sing downward one semitone at a time.
- Stop when the pitch becomes unstable, forced or too quiet to identify.
- Record the lowest repeatable note.
- Return to a comfortable middle pitch.
- Ascend gradually without shouting or squeezing.
- Record the highest repeatable, controlled note.
- Test on more than one day before accepting the result.
- Record modal, head, falsetto and whistle ranges separately when relevant.
You can calculate your vocal range after identifying the lowest and highest reliable notes.
Do not count microphone noise, inhaled sounds or accidental squeaks. If the tool shows an unexpected octave, repeat the pitch and verify it against a keyboard.
Can You Safely Increase Your Vocal Range?
Training can improve coordination near the current boundaries of your range. It may also reveal notes that were physically available but inaccessible because of tension or inefficient technique.
Safe development focuses on:
- Gentle warm-ups
- Balanced airflow
- Gradual semitone expansion
- Head-voice coordination
- Smooth register transitions
- Moderate volume
- Appropriate repertoire
- Adequate rest
Do not imitate infrasonic subharmonics or extreme whistle notes merely to match a record. Individual anatomy, training and vocal coordination vary considerably.
Stop if you experience pain, burning, sudden voice loss or persistent hoarseness. Ongoing symptoms should be evaluated by a qualified healthcare professional, preferably one with experience treating singers.
Frequently Asked Questions
Who has the widest vocal range in the world?
Guinness World Records recognizes Tim Storms as having the widest vocal range, measured at 10 octaves from approximately 0.7973 Hz to 807.3 Hz.
Who has the widest female vocal range?
Guinness recognizes Georgia Brown’s eight-octave range from G2 to G10 as the greatest vocal range by a female.
Does Mariah Carey have the widest vocal range?
No. Mariah Carey is famous for an exceptionally wide range and whistle-register notes, but she does not hold the current overall Guinness record.
Has anyone sung 10 octaves?
Guinness recognizes Tim Storms’ measured frequency span as 10 octaves. Much of its lower end is infrasonic, so it is different from a 10-octave range used in conventional music.
Is a six-octave vocal range possible?
Yes, but it is exceptionally unusual. Claims should identify which registers were included and whether the pitches were independently verified.
Do falsetto and whistle notes count?
They can count toward total phonational range. An evaluator may exclude them when measuring modal range, comfortable range or a particular style of singing.
What is the difference between vocal range and tessitura?
Vocal range covers the lowest to highest producible pitches. Tessitura is the area where the voice remains comfortable and effective through sustained music.
Can everyone expand their vocal range?
Many singers can improve access and control near their current boundaries. The amount of safe improvement varies, and record-level spans are not a realistic training target for most people.
