Lowest Note Test
Find the lowest note your voice can produce clearly.
Tip: Start with a comfortable low hum, then gradually sing lower. Keep each note steady for about one second. The tool records the lowest stable note detected while the test is running.
Microphone audio is processed in your browser and is not uploaded by this tool. Results depend on microphone quality, background noise, and vocal stability.
How low can you sing? Use this free online Lowest Note Test to check the lower end of your singing voice with your microphone. As you sing, the tool shows your current pitch and musical note, then saves the Lowest Note Reached and Lowest Frequency detected during the session.
Begin with an easy note and descend gradually. Your most useful result is the lowest clear note you can reproduce comfortably—not a brief creak, growl or unstable sound that happens to create a lower reading.
This test measures one endpoint of your voice. To combine your lowest and highest comfortable notes and calculate your complete singing range, use the homepage’s Vocal Range Finder.
What the Lowest Note Test Measures
The tool listens for the pitch of a single sung sound and reports it in two connected forms:
- Musical note: a note name with an octave number, such as C3 or A2.
- Frequency: the detected pitch measured in Hertz (Hz).
It also remembers the lowest detected pitch, so you can sing down through several notes without manually writing down every reading.
The tool measures pitch. It cannot determine whether a note felt comfortable, sounded full, belonged to your modal or chest register, or would be dependable in a song. You make those practical judgments by listening for clarity and checking whether you can repeat the note.
For a useful result, keep two observations:
- Lowest detected note: the lowest pitch captured by the tool.
- Lowest repeatable note: the lowest clear note you can sing again comfortably under similar conditions.
How to Use the Lowest Note Test
1. Prepare your voice and testing space
Test in a quiet room. Turn off music, videos, fans and other nearby sounds that could reach the microphone. Use the same microphone throughout the session and keep a consistent distance from it.
Warm up gently within a comfortable part of your voice before testing. Avoid repeatedly testing an already tired or hoarse voice.
2. Start the microphone test
Select Start Lowest Note Test and allow microphone access when your browser requests it. The microphone status should become active before you begin.
Start with a comfortable sustained note instead of beginning at the bottom of your range. This gives you a reference and lets you confirm that the tool is responding to your voice.
3. Move downward gradually
Sing one clear note at a time using the same comfortable vowel. Descend in small steps. Hold each note briefly so the pitch detector has a stable sound to analyze, then move to the next lower note.
Watch the Current Pitch and Current Note fields while you sing. The waveform gives a visual indication that the microphone is receiving a changing audio signal.
Continue only while the notes remain clear and comfortable. Stop descending when the sound becomes unstable, turns into uncontrolled creaking, requires you to press for the pitch or no longer feels like a note you could use in normal singing.
4. Verify the lowest note
Return to a comfortable note and rest briefly. Then try the possible lowest note again. A practical tracking method is to make up to three attempts with short rests. If two attempts are clear, controlled and comfortable, record the note as your repeatable low result for that session.
This two-of-three method is simply a consistent practice rule. It is not a clinical assessment or a formal voice-classification standard.
5. Copy or reset the result
Use Copy Results to copy the displayed result into your practice notes. Record the date, microphone used, test conditions and whether the note was clear modal or chest voice, vocal fry, or another deliberate technique.
If room noise, a voice crack or a detection error creates an implausibly low result, select Reset Low and repeat the test. Resetting clears the saved low; it does not change the microphone signal or improve the sung note.
How to Read Your Results
The live measurements change as you sing. The saved low remains at the lowest pitch captured until you reset it.
| Result | What it means |
|---|---|
| Current Pitch | The frequency detected at that moment, displayed in Hertz. |
| Current Note | The nearest musical note associated with the current detected pitch. |
| Live waveform | A visual sign that the microphone is receiving an audio signal; it is not the note result. |
| Lowest Note Reached | The musical note associated with the lowest pitch captured during the session. |
| Lowest Frequency | The lowest captured frequency, displayed in Hertz. |
In scientific pitch notation, the letter identifies the note and the number identifies its octave. C2 is one octave below C3. A flat or sharp changes the pitch by one semitone. The vocal range notes guide explains note names and octave labels in more detail.
Low-note frequency examples
The values below use equal temperament with A4 set to 440 Hz, following the standard note-and-frequency relationship explained by the University of New South Wales. They are reference points for interpreting the display, not goals that every singer should reach.
| Note | Reference frequency |
|---|---|
| C2 | 65.41 Hz |
| E2 | 82.41 Hz |
| G2 | 98.00 Hz |
| A2 | 110.00 Hz |
| C3 | 130.81 Hz |
| E3 | 164.81 Hz |
| G3 | 196.00 Hz |
| A3 | 220.00 Hz |
An octave lower has half the frequency: A2 is 110 Hz, while A3 is 220 Hz. A live voice may measure slightly above or below a reference frequency and still appear as the same nearest note.
Lowest Detected Note vs Lowest Usable Singing Note
A pitch detector can report the lowest sound it recognizes, but the smallest number is not automatically your most useful singing result.
Suppose Lowest Note Reached briefly shows A2, but the sound is weak and cannot be reproduced. If B2 is the lowest note you can sing clearly two times, record A2 as the detected low and B2 as the repeatable low for that session.
This distinction matters when choosing music. A song may technically touch your extreme low note, yet be difficult if several phrases remain near that boundary. Song suitability also depends on how long the low notes last, the vowel and lyrics used, the volume required and the notes surrounding them.
Your comfortable singing area can therefore be narrower than the complete span between your lowest and highest extremes. A lowest-note result is a useful endpoint, not a complete description of your voice.
Should Vocal Fry Count as Your Lowest Note?
Vocal fry is a very low, creaky or popping vocal quality produced below the usual modal register. It can be used intentionally as a vocal effect, but it answers a different question from your lowest clear singing note.
Irregular vocal-fry pulses can also make automatic pitch detection unstable. The display may jump, fail to settle on one note or save a result that is difficult to reproduce.
Choose the definition that matches your purpose:
- For a practical singing range, record the lowest clear, repeatable modal or chest-register note you can use comfortably.
- For an extended-effects range, test vocal fry separately and label the result as fry.
- For progress tracking, compare results made with the same vocal register and similar test conditions.
Do not combine a modal low from one session with a fry result from another and treat the difference as ordinary singing-range growth. If you want help working on clear low notes, see how to sing lower notes.
How to Get a Consistent Lowest-Note Result
Low-end results can change with warm-up, time of day, fatigue, illness, hydration, room noise, microphone response and the vocal register you choose. Use the same process when comparing sessions:
- Warm up before every test.
- Use the same microphone and similar input level.
- Keep approximately the same distance from the microphone.
- Sing in a quiet room without accompaniment.
- Use the same vowel and descend at a similar volume.
- Hold one note at a time instead of sliding continuously through the bottom.
- Repeat a possible new low before adding it to your practice record.
- Label modal or chest voice and vocal-fry results separately.
Compare a pattern across several sessions. One unusually low reading may reflect a different sound or testing condition rather than a lasting change in your usable range.
Why Very Low Notes Can Be Harder to Detect
A sung note contains a fundamental frequency plus higher harmonics. Pitch-detection software analyzes the repeating pattern and estimates the fundamental, but a weak fundamental, room noise, microphone limitations or irregular vocal production can lead to a wrong reading.
An octave error occurs when the detector reports a note an octave away from the note you intended. At the low end, a microphone may capture the upper harmonics more strongly than the fundamental and produce an octave-high reading. Noisy or irregular sounds can sometimes produce an unexpectedly low result instead.
Treat a sudden jump with caution. Reset the saved low, sing a clear sustained vowel and repeat the note. If the reading still looks wrong, use the Pitch Detector to check that individual sound separately.
Troubleshooting the Lowest Note Test
Microphone access is blocked or unavailable
Check the microphone permission for this website in your browser settings. Confirm that your device is using the intended microphone and that another application is not preventing access. After changing permission, reload the page and start the test again.
If you opened the page inside another app, try a regular browser. Testing the microphone in another application can help you determine whether the problem is the device input or the browser permission.
The note display jumps while I sing
Turn off competing sounds and sing one steady vowel at a comfortable volume. Keep the microphone position stable. A changing pitch, noisy onset, creaky tone or strong harmonic can make the detector switch between readings.
Return to an easy note and descend one step at a time. A clean note you can repeat is better evidence than a single fast jump on the display.
The saved note seems impossibly low
Use Reset Low, then repeat the note in a quieter room. Check whether the new reading is approximately an octave away from the first. Also listen for vocal fry or a growling sound that differs from your normal low-note production.
Do not keep an extreme result simply because it is lower. Record it only when you understand how you produced it and can reproduce it deliberately.
The test does not respond to a quiet low note
Confirm that the microphone is active and that its input level is adequate. Open Advanced Settings and review any available sensitivity or input controls, adjusting them in small steps if needed. Then test with a comfortable mid-range note before descending again.
Do not compensate by forcing the note or placing the microphone so close that the audio distorts.
Use Your Lowest Note to Find Your Full Vocal Range
Your lowest note is the lower endpoint. It does not show the width of your range or determine your voice type by itself.
Use the High Note Test to check the upper endpoint. Then enter both comfortable notes in the Vocal Range Finder to calculate your range in notes, semitones and octaves. For the complete process, follow the guide to finding your vocal range.
You can compare a complete result with common singing categories after testing both endpoints. A lowest note alone cannot identify a voice type; comfortable tessitura, register transitions and vocal qualities also matter.
Frequently Asked Questions
What is the lowest note I can sing?
Use the test to find your lowest detected pitch, then repeat that note after a short rest. For practical singing, keep the lowest note you can reproduce clearly and comfortably. Save a lower creak or special effect separately if you intentionally want to document it.
What is a good lowest note for a singer?
There is no universal lowest note that every singer should reach. Voices differ, and a lower result is not automatically better. Your useful low note is one that remains clear, comfortable and repeatable for your own singing.
Does a lower Hz number mean a lower note?
Yes. Frequency and perceived musical pitch are related: a lower fundamental frequency corresponds to a lower note. Moving down one octave halves the frequency, which is why A3 is 220 Hz and A2 is 110 Hz.
Can I include vocal fry in my vocal range?
You can document vocal fry as part of an extended or effects range. For a practical singing range, keep it separate from the lowest clear modal or chest-register note. Labeling the register makes later comparisons meaningful.
Is my lowest note enough to determine my voice type?
No. A single endpoint cannot classify a voice. Voice type also involves the overall range, the area where singing feels most comfortable, register transitions and vocal qualities. Use the site’s full range and voice-type tools for broader context.
Why does my lowest note change from day to day?
Warm-up, fatigue, health, testing time, microphone conditions and vocal production can change the result. Use similar conditions and compare several sessions rather than treating one reading as permanent.
How is microphone input handled?
The test needs microphone access to analyze your live pitch. Review the site’s Data Security page for its current explanation of microphone processing and stored data.
What should I do if low notes cause pain or lasting hoarseness?
Stop testing instead of forcing the sound. Rest a tired or hoarse voice. If pain, hoarseness or an unexpected voice change persists, seek advice from an appropriate healthcare professional. The National Institute on Deafness and Other Communication Disorders provides additional voice-care guidance.
