Bass is the lowest standard male singing voice, with a commonly cited range of approximately E2 to E4. Contralto is the lowest standard female voice type. Exceptional singers can descend much farther, but record-setting sounds below C1 are not representative of an ordinary, usable singing range.
The most extreme officially documented example belongs to Tim Storms. Guinness World Records measured his G−7 at 0.189 Hz—far below the threshold of human hearing. That extraordinary result should not be compared directly with a clear E2 or C2 that a bass can sustain and use in a song.
Understanding the lowest vocal range therefore requires separating four different things: voice type, usable range, tessitura and isolated record notes.
This voice range test tool can help you understand the overall span of your singing voice.
What Is the Lowest Vocal Range?
A vocal range is the span between the lowest and highest pitches a person can produce. However, the lowest sound someone can briefly create does not necessarily belong to their practical singing range.
For most singers, a low note should meet several conditions before it counts as usable:
- The pitch is identifiable.
- The note can be repeated reliably.
- It can be sustained briefly.
- It has enough clarity and volume to work musically.
- Producing it does not cause pain or excessive pressure.
The broader human vocal range includes everything from ordinary singing notes to unusual register effects. Within conventional voice classification, bass is the lowest male voice and contralto is the lowest female voice.
Lowest Voice Types and Recorded Notes
| Category | Typical or Recorded Low | What It Means |
|---|---|---|
| Standard male voice type | Bass, commonly around E2 at the lower end | Approximate classical range, not a fixed boundary |
| Exceptionally low bass | Sometimes C2, A1 or lower | May describe a basso profondo or oktavist |
| Standard female voice type | Contralto, commonly around F3 at the lower end | Approximate classical classification |
| Lowest male vocal note record | G−7 at 0.189 Hz | Produced by Tim Storms and measured by specialized equipment |
| Lowest female vocal note record | C♯1 at 34.21 Hz | Produced by Joy Chapman |
| Lowest practical note | Different for every singer | Must be clear, repeatable and usable without strain |
These categories are not interchangeable. A world-record sound, a singer’s lowest modal note and the bottom of a comfortable tessitura answer different questions.
What Is the Lowest Note Ever Produced by a Human Voice?
The official male record belongs to American bass singer Tim Storms. According to Guinness World Records, he produced a G−7 at 0.189 Hz on March 30, 2012, at Citywalk Studios in Branson, Missouri.
Two music professors and an acoustician witnessed the attempt. Specialized low-frequency equipment measured the output.
A frequency of 0.189 Hz completes fewer than one-fifth of a vibration per second. One cycle lasts approximately 5.3 seconds, placing it far below the usual human hearing threshold of about 20 Hz. Listeners cannot perceive it as an ordinary musical pitch in the same way they hear E2, C2 or even C1.
Storms’s result is therefore an exceptional measured vocal phenomenon—not a normal sustained bass note used melodically. His complete accomplishments and the distinction between his lowest-note and widest-range records belong in a separate examination of Tim Storms’s vocal range.
What Is the Lowest Female Vocal Note?
Guinness recognizes Canadian singer Joy Chapman for the lowest vocal note produced by a female. She recorded a frequency of 34.21 Hz, identified as C♯1, in Surrey, British Columbia, on February 21, 2021. The result is documented on the official Guinness female vocal-note record page.
This record is much lower than the conventional contralto range. It demonstrates why individual capability and record performances should not be treated as the boundaries of a voice type.
Contralto remains the lowest conventional female classical classification, but not every woman with a low note is a contralto. Timbre, tessitura, registration and the part of the range that remains comfortable are also important. The wider female vocal range guide explains how contralto relates to mezzo-soprano and soprano.
How Low Does a Typical Bass Sing?
A bass voice is commonly described as spanning approximately E2 to E4 in classical singing. Some sources place its lower boundary around C2 or D2, depending on the repertoire and classification system.
These figures are references rather than strict limits. A bass does not need to possess a record-setting low note, and touching E2 once does not automatically make someone a bass.
Voice classification also considers:
- Comfortable tessitura
- Vocal weight and timbre
- Register transitions
- Projection across the range
- Repertoire the singer can sustain
- Training and stylistic context
A singer learning how a bass voice is classified should focus on where the voice consistently functions, not just its lowest morning note.
Basso profondo and oktavist
A basso profondo is an especially deep bass with a low tessitura and substantial resonance. An oktavist is a specialized low bass associated particularly with Russian Orthodox choral traditions. Some oktavists sing down to A1, G1 or lower, although these abilities are rare.
“Contrabass” is sometimes used informally for an extraordinarily low singer, but it is not as consistently standardized as bass, basso profondo or oktavist. It should not automatically be treated as a separate universal voice type below bass.
Among conventional male vocal ranges, bass remains the lowest category, below baritone and tenor.
Modal Low Notes, Vocal Fry and Subharmonics
Not all low vocal sounds are produced in the same way.
| Production | General Character | How It Relates to Range |
|---|---|---|
| Modal voice | Clear, connected singing quality | Most relevant to ordinary usable range |
| Vocal fry | Irregular, creaky pulses at very low frequency | Can extend below modal voice but may have limited musical use |
| Subharmonics | A lower pitch created through a more complex vibration pattern | Can produce notes below the singer’s normal fundamental |
| Brief extreme sound | Momentary low-frequency output | Should not automatically count as usable range |
Vocal fry is not inherently proof of a bass voice. Many people can make a low creaky sound regardless of where their normal singing voice sits.
Subharmonics can produce recognizable pitches below a singer’s modal range, and skilled performers may use them musically. Even so, a subharmonic note should be identified as such when comparing ranges. A resonant modal C2, a quiet fry C2 and a subharmonic C1 represent different vocal achievements.
Usable Range, Total Range and Tessitura
Your total range may include every pitch you can produce under test conditions. Your usable range is narrower: it contains the notes you can sing clearly and repeatedly. Tessitura is narrower still, describing the area where your voice remains most comfortable and effective over time.
For example, a singer might touch C2 in fry, produce E2 clearly in modal voice and feel most comfortable from G2 to D4. In that case:
- C2 is an extreme effect.
- E2 is the lowest usable modal note.
- G2 to D4 is closer to the comfortable singing area.
This distinction matters more than claiming the largest possible span. Our explanation of vocal tessitura shows why comfortable range is often more useful for selecting songs and identifying voice type.
To measure your lowest usable note, descend gradually at a moderate volume. Repeat each pitch and stop counting when the sound becomes unstable, excessively breathy, pressed or impossible to reproduce. A vocal range calculator can help organize the results, but the microphone reading still requires musical interpretation.
Can You Train Your Voice to Sing Lower?
Training may make existing low notes easier, clearer and more consistent. It may also reveal notes that were previously hidden by tension or inefficient coordination. It cannot guarantee a particular note or transform every voice into a bass.
When working downward:
- Warm up in a comfortable middle range first.
- Descend in small steps rather than jumping to the lowest target.
- Keep the jaw, tongue and neck relaxed.
- Use a comfortable volume.
- Avoid deliberately pushing the larynx downward.
- Stop if the voice becomes painful or persistently hoarse.
The goal is to improve coordination and resonance, not force the vocal folds beyond their natural limits. Follow a gradual approach when learning how to extend your lower vocal range.
If low-note practice causes pain, recurring voice loss or hoarseness that does not resolve, pause the exercises and seek guidance from a qualified voice professional or healthcare provider.
Common Misconceptions About Extremely Low Voices
One low note proves someone is a bass.
Voice type depends on much more than one pitch. Tessitura, timbre, register transitions and sustainable repertoire matter.
Every produced sound belongs to a singer’s musical range.
An unstable fry pulse or momentary subharmonic may demonstrate an effect without being usable in ordinary singing.
The singer with the lowest note has the widest range.
Lowest note and total span are separate measurements. A singer can descend exceptionally low without possessing the widest overall range.
A deep speaking voice guarantees a bass singing voice.
Speaking pitch may offer a clue, but it cannot determine vocal classification by itself.
Lower is always better.
A clear, resonant E2 is more useful than a forced C1 that cannot be repeated or incorporated into music.
Frequently Asked Questions
What voice type has the lowest vocal range?
Bass is the lowest conventional male voice type. Contralto is the lowest conventional female voice type. Basso profondo and oktavist describe exceptionally low bass singers.
What is the lowest note produced by a human voice?
Guinness lists Tim Storms’s G−7 at 0.189 Hz as the lowest vocal note produced by a male. It was measured with specialized equipment and is far below normal human hearing.
What is a normal low note for a bass singer?
E2 is a commonly cited lower boundary for a classical bass, although some basses sing comfortably to D2 or C2. Individual ability and repertoire vary.
What is the lowest female voice type?
Contralto is the lowest conventional female classical voice type. It should be identified through tessitura and vocal character, not one isolated low note.
Does vocal fry count as vocal range?
It can be recorded as part of a singer’s total producible range, but it should be labelled separately from the usable modal singing range.
Can anyone learn to sing below C2?
No. Training can improve coordination, but anatomy and natural vocal characteristics place individual limits on how low someone can sing clearly.
How can I identify my lowest usable note?
Descend gradually, repeat each pitch and count only notes that remain recognizable, stable and free from excessive pressure. Stop when the voice shifts into an uncontrolled effect or becomes uncomfortable.
