How many octaves can you sing? This octave range test finds your lowest and highest notes, from your microphone or from notes you choose, and turns them into your vocal range in octaves and semitones. It also shows how much of each octave on the piano you can sing, so you can see where your voice sits as well as how wide it is.
Octave Range Test
Find out how many octaves your voice covers. Sing your lowest and highest notes into the microphone, or choose them, to get your range in octaves and semitones with an octave-by-octave breakdown.

How to Take the Octave Test
- Press Start the test and allow microphone access.
- Sing “ah” and slide down slowly, holding each note for about a second. The tool keeps your lowest steady note. Press Save when it shows the note you want.
- Now slide up the same way and save your highest steady note. Stop before your voice strains.
- Read your result: the number of octaves, the semitones, the interval and the octave-by-octave bars.

How Octaves Are Counted
An octave is 12 semitones: from one note to the next note with the same name, such as C3 to C4. The frequency doubles with each octave, so C3 is 131 Hz and C4 is 262 Hz. The test counts the semitones between your two notes and divides by 12.
| Your range | Semitones | Octaves | Interval |
|---|---|---|---|
| C3–C4 | 12 | 1 | 1 octave |
| A2–E4 | 19 | 1.58 | 1 octave + perfect 5th |
| C3–C5 | 24 | 2 | 2 octaves |
| F3–C6 | 31 | 2.58 | 2 octaves + perfect 5th |
| E2–E5 | 36 | 3 | 3 octaves |
For other note pairs, the vocal range calculator also shows each note’s frequency and the closest voice type.
Octave by Octave: Where Your Voice Sits
Pianos and singers number octaves from C: octave 3 runs from C3 to B3, and middle C is C4. The bars show how many of the 12 notes in each octave you can sing. Two singers can both have “2 octaves” and still sit in very different places: A2–A4 is typical of a baritone, and A3–A5 of a mezzo-soprano. That’s why the tool shows position as well as width. It also counts how many complete octaves you cover, every note from C to B.
How Many Octaves Is a Normal Vocal Range?
- Under 1 octave: usually a sign that you haven’t warmed up yet, or that you’re testing only your most comfortable notes.
- About 1.5–2 octaves: common for adults without vocal training.
- 2–3 octaves: a wide range, typical of practised singers.
- 3 octaves or more: rare in usable voice. Check whether falsetto, whistle notes or vocal fry are included.

Should Falsetto and Head Voice Count?
Count every note you can sing clearly and repeat. Many singers list falsetto separately, because it sounds different from full voice. Whatever you choose, be consistent from test to test so your results are comparable. See does falsetto count in vocal range? Notes you can hit only once, or only with strain, inflate the number without helping you sing songs.
Tips for an Accurate Result
- Warm up for a few minutes first; a quick vocal warm-up is enough.
- Test in a quiet room with no music playing. Keep a steady distance from the microphone.
- Sing on an open vowel like “ah”, and hold each note until the tool shows it.
- If a note looks wrong (usually an octave too high or too low on very quiet notes), sing it a little louder, or use Choose notes with notes checked on a piano.
Frequently Asked Questions
How many octaves do I have?
Take the test above. Your result shows your range in octaves to two decimal places, such as 1.58, and how many complete octaves you sing, every note from C to B.
Can I increase my octave range?
Yes, gradually. Regular, relaxed practice usually adds a few notes at each end over weeks and months. Our guide on how to improve your vocal range explains safe exercises.
Is my voice recorded?
No. Pitch is detected in your browser while you sing, and nothing is saved or uploaded.
