Short answer: no singer has a measured range of exactly seven octaves, but Guinness World Records lists two singers who go beyond it: Tim Storms (10 octaves, male record, 2008) and Georgia Brown (8 octaves, female record, 2004). Singers such as Mike Patton, Dimash Kudaibergen, Minnie Riperton and Mariah Carey are usually credited with five to six octaves. Most trained singers use two to three.
A 7-octave vocal range would cover almost the whole 88-key piano, which spans just over seven octaves from A0 to C8. That is why “7 octave singers” lists are so popular, and also why so many of them mix measured records with fan estimates. Below you will find the singers with the most octaves, sorted by what is actually documented, plus a quick way to measure your own span with our free vocal range test.
Singers With 7+ Octave Ranges: Verified vs Claimed
The table ranks the multi-octave singers people search for most. “Guinness record” means a measured, witnessed attempt; “widely reported” means the figure appears in many interviews and articles but comes from recordings, not a formal test.
| Singer | Range most often cited | Status | Known for |
|---|---|---|---|
| Tim Storms | 10 octaves, G−5 to G5 | Guinness record (greatest vocal range, male), 2008 | Also holds the lowest note ever sung, G−7 |
| Georgia Brown | 8 octaves, G2 to G10 | Guinness record (greatest vocal range, female), 2004 | Highest note on record, G10 |
| Mike Patton | about 6 octaves | Widely reported | Faith No More, Mr. Bungle; screams to crooning |
| Dimash Kudaibergen | about 6 octaves | Widely reported | “SOS d’un terrien en détresse” |
| Minnie Riperton | about 5½ octaves | Widely reported | Whistle notes in “Lovin’ You” |
| Axl Rose | F1 to B♭6 (about 5.4 octaves) | Topped a widely shared 2014 comparison built from recordings | Low growls to high rock screams |
| Mariah Carey | about 5 octaves | Widely reported | Whistle register, “Emotions” |
| Yma Sumac | often quoted as more than 4 octaves | Widely reported | 1950s exotica recordings |
| Freddie Mercury | about 4 octaves (popular figure) | Not confirmed by a 2016 acoustic study of his voice | Queen; very fast, irregular vibrato |
| Ariana Grande | about 4 octaves | Widely reported | Whistle notes, light head voice |
| Adam Lopez | whistle-register specialist | Held the Guinness record for the highest male note until Wang Xiaolong’s 2017 E8 | Male whistle notes |
| Vitas | no reliable figure | Fan estimates only | Very high male falsetto |
Only the first two rows come from a measured test. The single record behind the top row, including how Guinness counted it, is explained on our widest vocal range page.
The Only Documented 7+ Octave Singers
Tim Storms: 10 octaves
Guinness lists Tim Storms, the bass singer of the vocal group Pierce Arrow, with a range of 10 octaves from about G−5 to G5, measured in Branson, Missouri, in August 2008. Most of that span lies below the range of human hearing: the bottom octaves are produced in the vocal fry register and were captured with measuring equipment rather than heard as tones. In 2012 he also set the record for the lowest note, G−7 (listed at 0.189 Hz). Our lowest vocal range guide covers that note in detail.
Georgia Brown: 8 octaves
The Brazilian singer Georgia Brown holds the female record: eight octaves from G2 (98.00 Hz) to G10, verified in São Paulo in August 2004 by music experts using a piano, a violin and a Hammond organ. G10 works out to about 25,088 Hz, above what most adults can hear, so it is better thought of as a frequency than a musical note. See the highest vocal range page for the full story of the highest notes ever sung.
6-Octave and 5-Octave Singers
Below the two record holders sits a small group of performers whose recordings show five to six octaves. These numbers are measured from the lowest and highest notes found anywhere in their catalogue, often from different songs and very different vocal techniques, so they describe an extreme span rather than a range the singer uses in every song.
- Mike Patton is frequently quoted at six octaves, moving from deep croon to falsetto, screams and vocal effects.
- Dimash Kudaibergen is often described as having around six octaves, from baritone lows to whistle-like highs.
- Axl Rose topped a 2014 comparison chart that measured his lowest and highest recorded notes, F1 and B♭6.
- Minnie Riperton and Mariah Carey are the classic 5-octave-plus examples, both famous for the whistle register.
If you are curious how these highs are produced, our tips on the whistle register explain why these notes are so hard to sing and to measure.
Singers People Look Up: A Reality Check
Many searches that reach this page are for a single artist, for example Tori Kelly, Jack White, Jacob Collier, Bonnie Tyler, Jeff Buckley, Michael Jackson, Freddie Mercury, Steve Perry, Stevie Wonder, Kelly Clarkson, Billie Eilish, Chris Cornell, Chester Bennington, Lady Gaga, Beyoncé, Bruno Mars, Etta James, Sarah Brightman, Diana Ankudinova, Pat Benatar or David Byrne. None of them is documented with a 7-octave range. Published figures for famous pop, rock and soul voices are almost always estimates compiled by fans from recordings, and they rarely reach the multi-octave numbers above. A great voice is about control and tone, not octave count.
Bass specialists such as Tim Foust and Geoff Castellucci are known for how low they go rather than for total range, country singers such as Josh Turner and Randy Travis for deep baritone tone, and opera singers like the bass-baritone Bryn Terfel are classified by voice type, not by octave count. To see where those voice types sit, open the vocal range chart.
What Is an Octave, and How Many Octaves Are There?
An octave is the distance between one note and the next note with the same name, where the frequency doubles. A4 is 440 Hz, so A5 is 880 Hz and A3 is 220 Hz. Octaves are numbered in scientific pitch notation starting at C0 (16.35 Hz); middle C is C4 (261.63 Hz).
| Span | Notes | Octaves |
|---|---|---|
| 88-key piano | A0 (27.50 Hz) to C8 (4,186.01 Hz) | 7.25 |
| Human hearing | about 20 Hz to 20,000 Hz | about 10 |
| Typical bass voice | E2 to E4 | 2 |
| Typical soprano voice | C4 to C6 | 2 |
| Tim Storms (record) | G−5 to G5 | 10 |
| Georgia Brown (record) | G2 to G10 | 8 |
So a 7-octave singer would need to cover roughly the whole piano keyboard with the voice alone. Every note and its exact frequency is listed in our musical note frequency chart, and the vocal range notes guide shows which notes each voice type usually sings.
How Many Octaves Can the Average Person Sing?
- Untrained adult: about 1.5 to 2 octaves.
- Trained singer: about 2 to 3 octaves of usable, in-tune range.
- Professional with a wide range: 3 to 4 octaves.
- Rare: 5 to 6 octaves, usually including whistle register or vocal fry.
- Record territory: 8 and 10 octaves (Georgia Brown, Tim Storms).
Typical numbers for each group are covered in average vocal range for men and average vocal range for women. The broader picture of what a human voice can do is in our human vocal range guide.
Why a 7-Octave Voice Is So Rare
A span that wide needs every register working in one throat: vocal fry for the deepest notes, chest voice, head voice or falsetto, and whistle register at the top. Most people have easy access to two or three of these. Vocal fold length and thickness set the natural limits, so training can make more of your range usable and add some notes at the edges, but it cannot turn a 2-octave voice into a 7-octave one.
If you want to work on the edges safely, start with our guide on how to extend your vocal range.
Measure Your Own Octave Range
- Warm up for five minutes with gentle sirens and lip trills.
- Slide down to your lowest clear note and hold it for a second while the test listens.
- Slide up to your highest clear note, including falsetto if you use it.
- Read the lowest and highest note: every 12 semitones between them is one octave.

Questions About 7-Octave Singers
Who has a 7-octave vocal range?
No singer is documented with exactly seven octaves. Tim Storms (10 octaves) and Georgia Brown (8 octaves) are the only Guinness-listed ranges above seven.
Which male singers have a 7-octave range?
Tim Storms is the only man with a measured range above seven octaves. Mike Patton and Dimash Kudaibergen are usually quoted around six.
Are online octave claims reliable?
Treat them as estimates. Unless a figure comes from a witnessed test, such as a Guinness record, it is usually built from the lowest and highest notes found across many recordings.
