Vocal Range Calculator

Enter the lowest and highest notes you can sing comfortably to get the span in semitones and octaves, the frequency limits, and the standard voice ranges that contain it.

scientific pitch, e.g. E2 or Ab3
scientific pitch, e.g. C5 or F#4

Notes are read as scientific pitch, where middle C is C4 and A4 is the 440 Hz reference. Frequencies follow 12-tone equal temperament, so each semitone multiplies the pitch by 21/12 and one octave doubles it. The voice types are the common classical and choral reference ranges, and they are approximate: classifications differ between traditions, choral sections and Fach systems, and a range on one day is not a diagnosis. Head voice, falsetto, passaggio and comfortable tessitura are not modelled, so treat a match as a comparison rather than a verdict.
