The highest of the six broad classical voice categories, typically centered above middle C. The C4–C6 span is a reference convention, not a pass/fail boundary: trained singers, repertoire, registration, and individual anatomy create substantial overlap.
Soprano reference notes
- Typical span
- C4–C6
- Use it as
- A comparison, not a boundary
Tessitura: A soprano usually feels most efficient in the upper part of the staff; usable extremes alone do not establish the category.
Nearest category: A mezzo-soprano may reach many of the same notes but often has a lower comfortable center and different passaggi.
Reported examples
- Whitney Houston — A2–E6, includes whistle disputed. Reported ~3.5 octaves.
- Ariana Grande — D3–E7, includes whistle disputed. Top octave is whistle register; heavily inflated online.
- Mariah Carey — G2–G7, includes whistle disputed. Famous ~5 octaves ONLY with whistle register.
Singer ranges are reported and approximate, often include falsetto/whistle register, and are widely disputed online. Shown for fun, not as fact.

Questions and limitations
Does reaching C6 make me a soprano?
Not by itself. A single top note says little about where your voice is comfortable over a phrase. Use the sustained range as one clue, then consider tessitura, tone, register transitions, and guidance from a qualified teacher.
Can vocal range alone determine my voice type?
No. Range is useful evidence, but classical classification also considers tessitura, timbre, passaggio, vocal weight, training, and repertoire. This tool therefore gives an estimate and shows borderline matches instead of presenting a range-only result as a professional diagnosis.
Why does the test ignore very brief notes?
A microphone can mistake breath, room noise, or a harmonic for an extreme pitch. A note must remain clear and stable for at least 300 milliseconds before it changes your result, which favors notes you can actually sustain.
