Every musical note has an exact frequency measured in hertz (Hz) — the number of vibrations per second. A4 = 440 Hz is the international tuning standard. Middle C (C4) = 261.63 Hz. Understanding vocal range in Hz gives a universal, precise measurement that transcends notation systems and applies equally to voice type classification, acoustic analysis, and tool calibration. This page is the complete Hz reference for every voice type, note, and vocal category.

Using Hz to Identify Your Voice Type
Hz measurements remove subjectivity from voice type identification:
- Use the find my vocal range online tool to find your lowest and highest note
- Find those notes in the tables above to see their Hz values
- Compare your Hz range to the Master Reference Table at the top of this page
- Confirm with the voice type test which automatically does this analysis
- Check your speaking voice with the voice hz test for additional confirmation
The vocal range calculator converts any note name to Hz automatically. The singer comparison tool visually maps your Hz range against any documented artist.
Frequently Asked Questions
What Hz is middle C? Middle C (C4) = 261.63 Hz. It is the most commonly referenced vocal frequency and sits exactly in the middle of the piano keyboard — the universal midpoint of the musical range.
What Hz is A4 (concert pitch)? A4 = 440 Hz. This is the international tuning standard used by orchestras worldwide. When an orchestra tunes, every instrument is tuned to A4 = 440 Hz.
What Hz is soprano C? Soprano C (C6) = 1,046.5 Hz. It sits exactly two octaves above middle C and is the traditional upper benchmark for classical soprano voices.
What Hz is a deep male voice? A deep baritone speaking voice typically sits between 85–110 Hz. A bass singing voice operates from approximately E2 (82.4 Hz) downward. The deepest documented bass singers reach into the 40–60 Hz range for their lowest notes.
What Hz is a whisper? Whispering does not have a clear fundamental frequency in the same way voiced speech does — it is produced by turbulent airflow without vocal cord vibration. However, the spectral characteristics of whispers typically cluster around 200–800 Hz.
How do I find my Hz vocal range? Use the voice hz test for your speaking voice, the find my vocal range online for your full singing range in Hz, or the vocal range calculator to convert note names to Hz values.
