Vocal Range Test (Voice Type Finder)

Your vocal range is the span from the lowest to the highest note you can sing comfortably. This test works it out three ways: enter the two notes if you know them, sing a slow slide into the microphone, or analyse a recording. It shows the range in semitones and octaves and compares it with the six classical voice types (bass, baritone, tenor, alto, mezzo-soprano and soprano), so you can pick songs and keys that suit you. The microphone and recordings are analysed in your browser and never uploaded.

How to use this tool

1. Choose how you want to measure: by notes, by microphone or from a recording.
2. For the microphone, press Calculate, allow access and sing "ah" from your lowest comfortable note slowly up to your highest; press Stop and analyse.
3. Read your lowest and highest notes, the range and the closest voice type.
4. Compare with the table of typical ranges to see which parts suit you.

Formula

Range = highest − lowest (semitones) · octaves = semitones ÷ 12 · match = shared semitones ÷ semitones covered by either range

Notes are counted in equal temperament with A4 = 440 Hz (middle C = C4 = 261.6 Hz). The typical ranges used are bass E2–E4, baritone A2–A4, tenor C3–C5, alto F3–F5, mezzo-soprano A3–A5 and soprano C4–C6. From the microphone or a recording, the pitch is measured about every 64 ms with the YIN method, and a note counts as your lowest or highest only when it is held for at least 0.2 s, so a crack or a breathy glide does not stretch the result.

Example

Someone whose lowest comfortable note is A2 (110 Hz) and highest A4 (440 Hz) has a range of 69 − 45 = 24 semitones, exactly 2 octaves. That matches the baritone range A2–A4 completely, while tenor (C3–C5) shares 21 of 27 semitones and bass (E2–E4) 19 of 29.
