This high note test finds the highest note you can sing and hold: the target notes climb one step at a time, and a note only counts when you hold it steadily for about a second. Choose where to start, sing each target on “ah” and keep climbing until a note is out of reach. You get your highest held note with its name, frequency in Hz and octave.
High Note Test
Climb toward your highest note. Each target note is one step higher: sing it and hold it for about a second to clear it. Your result is the highest note you held.
Press Start and allow microphone access. Sound is analysed in your browser; nothing is recorded or uploaded.
Top bar: microphone level · bottom bar: hold the note until it fills (about 1 second)

How to Use the High Note Test
- Warm up for a few minutes first. A cold voice rarely reaches its top notes.
- Choose Start from: Lower voice (bass, baritone) starts on C3, Middle voice (tenor, alto) on G3, Higher voice (mezzo, soprano) on C4, and Trained high voice on C5. Start low enough that the first notes feel easy.
- Choose Step up in semitones (the most precise result) or whole tones (a faster climb), and how close a note must be: Relaxed (±50 cents), Standard (±35 cents, the default) or Strict (±20 cents).
- Press Start high note test and allow microphone access. The first target note plays for one second. Untick Play each target note if you only want to see the note name and Hz.
- Sing the note on “ah” and hold it until the bottom bar fills. The note is cleared and the next, higher note plays. Press Replay note to hear the target again.
- The climb ends when you cannot hold a note in two tries, when you reach C7 (the top of the test) or when you press Stop and see result. Then use Copy result to save it or Test again for a new climb.
How the Hold Rule Works
A quick squeak near the right pitch is not the same as a note you can sing. So each target counts only when your voice stays within the tolerance you chose, for example ±35 cents (a cent is one hundredth of a semitone), for one full second. Breaks of up to 0.15 seconds, like a short vibrato swing or a mic dropout, do not reset the hold. Longer breaks start the hold again.
- You get 8 seconds per try, counted from the end of the target tone, and two tries per note.
- The microphone is ignored while the target tone plays, so the tone itself is never scored.
- Singing the right note in the wrong octave does not count. If you are an octave below the target, the tool tells you so.
- Your pitch on a cleared note is the middle (median) of the held second, after skipping its first part, where most singers slide into the note.
Understanding Your Test Results
- Highest held note: the highest target you held for a second, with its standard frequency and octave, for example A5 · 880.0 Hz · octave 5.
- Steps cleared and climb from your first note: how many targets you held and how many semitones above your first note you got.
- Your pitch on that note: the Hz you actually sang and how many cents sharp or flat it was.
- Highest note you sang (any length): the highest pitch you kept steady for at least a quarter of a second at any point. It is shown for interest and marked “not held for 1 second” when it is above your held note. It never replaces the held result.
- Why the climb ended, your settings and a table of every target, held or not.
The result is your highest held note today, with this microphone and these settings. It can change with warm-up, time of day and vowel, so compare climbs that use the same settings.
Understanding High Notes and Their Importance
Your highest note sets which songs and parts you can sing without strain. Soloists use it to choose keys, choir singers to pick a part, and musical theatre singers to check whether a role is in reach. Every note name has a fixed frequency (with A4 = 440 Hz), and each octave up doubles it. If note names and octave numbers are new to you, see how vocal range notes are named. These landmarks help you place your result:
| Note | Frequency | Why it matters |
|---|---|---|
| C5 | 523.3 Hz | “Tenor high C”, the classic top note for tenors |
| A5 | 880.0 Hz | Near the top of a typical mezzo-soprano range |
| C6 | 1,046.5 Hz | “Soprano high C”, the top of a typical soprano range |
| F6 | 1,396.9 Hz | The top note of the Queen of the Night’s aria in Mozart’s The Magic Flute |
| C7 | 2,093.0 Hz | The highest target in this test |
Voice Type High Note Standards
Different voice types have different natural top notes. The table shows the typical ranges used in choir and classical writing. Many singers, especially trained singers and those using falsetto or head voice, sing above these notes, so treat them as a guide, not a limit.
| Voice type | Typical range | Typical top note | Start the test from |
|---|---|---|---|
| Soprano | C4–C6 | C6 (1,046.5 Hz) | Higher voice (C4) or Trained high voice (C5) |
| Mezzo-soprano | A3–A5 | A5 (880.0 Hz) | Higher voice (C4) |
| Alto (contralto) | F3–F5 | F5 (698.5 Hz) | Middle voice (G3) |
| Tenor | C3–C5 | C5 (523.3 Hz) | Middle voice (G3) |
| Baritone | A2–A4 | A4 (440.0 Hz) | Lower voice (C3) |
| Bass | E2–E4 | E4 (329.6 Hz) | Lower voice (C3) |
For the full note spans of each voice, see the female vocal range chart and the male vocal range chart.
Chest Voice, Head Voice, Falsetto and Whistle Register
The test measures pitch, not how you make the sound. A note held in chest voice, mix, head voice or falsetto counts the same, and the tool cannot tell which one you used. Many singers reach their highest notes only after switching register, so if you get stuck at one note, read about chest voice vs head voice and try the next note lighter.
The whistle register is the highest register and is usually used above about C6. The detector follows pitches up to about 2,150 Hz, so whistle notes up to C7 (2,093 Hz) can be measured. Anything higher shows as “Above this test’s range” and is not counted. If you are working on these notes, see how to do the whistle register safely.
Highest Held Note vs Your Full Vocal Range
This page is a high note challenge: it only climbs upward and reports the top note you could hold. It does not measure your lowest note, your full range in octaves or your voice type. For that, use the vocal range test in the Related Tools above. To see how high the most famous singers go, read about the highest vocal ranges on record and what a 5-octave vocal range means.
Safety Considerations for High Note Training
- Warm up first. A short routine from vocal warm-ups for beginners gets your voice ready for the top of your range.
- Stop at strain. Pain, hoarseness, a scratchy throat or a voice that cuts out are signals to stop and rest, not to push harder. The two-tries rule is there so you don’t keep forcing the same note.
- Don’t test too often. Once a week is enough to see progress. Testing several times a day only tires your voice.
- Get help if it keeps hurting. A qualified singing teacher can spot tension or breath problems. Ongoing pain or hoarseness is a reason to see a doctor. This tool is a practice guide, not a medical test.
Quick Reference: High Note Exercise Progressions
| Exercise | Time | What it helps with |
|---|---|---|
| Lip trill slides | About 5 minutes | Smooth moves between registers with less tension |
| “Ng” hum climbs | About 5 minutes | Light, easy access to the top of your range |
| Straw phonation | About 5 minutes | Singing high with less effort in the throat |
| Sirens | About 5 minutes | Crossing the break between chest and head voice |
| “Oo” vowel glides | About 10 minutes, 3 times a week | Flexibility across the range |
| Octave leaps | About 8 minutes, 3 times a week | Landing high notes cleanly and with confidence |
Then retake the high note test with the same settings and compare your highest held note. For a longer plan, see how to extend your vocal range.
Microphone, Accuracy and Privacy
- Use headphones if you can, and test in a quiet room with your phone or microphone at arm’s length. Loud music, other voices and background noise make notes harder to hold.
- Sing one clear voice on an open vowel like “ah”. Whispering and very breathy notes may not be measured.
- The detector follows pitches from about 70 to 2,150 Hz. Some phone microphones and noise filters weaken very high notes, which can stop a note from being held even when you sang it.
- The test needs microphone access on a secure (https) page and stops if you switch tabs or lock your phone.
- Sound is analysed in your browser while you sing. The tool does not record, store or upload your voice. See the privacy policy for the wider site.
Frequently Asked Questions About High Notes
How high can I sing?
Take the test above: your highest held note is the top note you could sing steadily for a second today. To see what it means for your voice, compare it with the typical top notes in the voice type table above.
What is a good high note?
It depends on your voice type. C5 (tenor high C) is a strong top note for a tenor, and C6 (soprano high C) for a soprano. A good result is one you can hold without strain.
Why do I have to hold each note?
Holding a note for a second shows it is a note you can actually use. It also stops a brief crack or a stray noise from being counted as your highest note.
Does it count falsetto, head voice and whistle notes?
Yes. The test measures pitch only, so any register counts, up to C7 (2,093 Hz). It cannot tell which register you used.
Why does it say I sang an octave below the target?
You matched the note name but sang it one octave lower, which is common for men matching a high tone. Only the exact octave counts, so try the same note higher, often in a lighter head voice or falsetto.
How long does it take to expand my high notes?
With regular practice, many singers notice easier high notes within a few months. Progress varies a lot from person to person, so compare your results over weeks, not days.
Should I warm up before singing high notes?
Yes. Spend five to ten minutes on gentle humming, lip trills and slides before the test. A warmed-up voice usually reaches higher and with less effort.
Is it bad to push for high notes?
Forcing notes with a tight throat can tire or strain your voice. If a note hurts or feels scratchy, stop. Extend your range gradually and rest when your voice is tired.
How often should I test my high notes?
Once a week or every two weeks is enough to track progress. Use the same settings each time so the results are comparable.
Is my voice recorded or uploaded?
No. Sound is analysed in your browser as you sing and is not recorded, stored or uploaded by the tool.
