What this calculator does
A vocal range is the span from the lowest to the highest note a singer can comfortably produce, and it is the main figure used to sort voices into the standard classification system: bass, baritone and tenor for lower voices, contralto, mezzo-soprano and soprano for higher ones. Entering a lowest and highest comfortable note here compares that span against the typical published range for each voice type and reports the closest match.
These six categories are long-established reference points in vocal music, not something that shifts over time, but the classification here is a starting point based on range alone. A singing teacher also weighs vocal weight, tone colour and where the voice sits most comfortably (its tessitura), which range figures alone cannot fully capture.
The formula
Each note entered, such as C3 or F#4, is converted to a semitone position on the standard piano scale. The voice type whose published low and high notes are the closest overall match to the entered range is reported as the result.
| Term | Meaning |
|---|---|
| Vocal range | The full span from the lowest to the highest note a singer can produce, expressed as two notes. |
| Voice type | One of the six standard classifications: bass, baritone, tenor (typically male), or contralto, mezzo-soprano, soprano (typically female). |
| Octave | A span of 12 semitones; doubling or halving a note's frequency. |
| Note naming | Notes are written as a letter (A to G), an optional sharp (#) or flat (b), and an octave number, such as G#4 or Bb2. |
The inputs explained
| Field | What to enter |
|---|---|
| Lowest comfortable note (e.g. E2) | The lowest note you can sing comfortably, without straining, written like E2 or Bb2. |
| Highest comfortable note (e.g. G5) | The highest note you can sing comfortably, written like G5 or F#4. |
| Voice | Narrows the comparison to the three typically male or three typically female voice types, or checks all six if left on "not sure". |
When to use it
Choosing choir or ensemble parts
Knowing a rough voice type before an audition helps decide whether to prepare a piece pitched for a lower or higher part.
Working with a vocal coach
A range measured at home gives a useful starting figure to bring to a first lesson, to be refined once tone and comfortable register are assessed properly.
Tracking range over time
Vocal range can extend gradually with training. Re-entering the current comfortable range every so often shows how far it has moved since a previous check.
Worked examples
Every figure in the tables below is produced by this page’s own calculator at build time, so the numbers and the tool always agree. Select any row to load that scenario.
What voice type matches different ranges?
The same top note with a range of lower notes, checked against all six voice types.
| Lowest note | Closest voice type | Range width |
|---|---|---|
| C2 | Bass | 3.0 octaves (36 semitones) |
| E2 | Bass | 2.7 octaves (32 semitones) |
| A2 | Baritone | 2.3 octaves (27 semitones) |
| C3 | Tenor | 2.0 octaves (24 semitones) |
| F3 | Tenor | 1.6 octaves (19 semitones) |
| A3 | Tenor | 1.3 octaves (15 semitones) |
Questions
What vocal range am I?
Enter your lowest and highest comfortably sung notes above and this tool compares that span against the six standard voice types to report the closest match. It is a useful starting estimate rather than a formal classification.
What is the average vocal range?
Most untrained adult voices comfortably cover around 1.5 to 2 octaves, with trained singers often extending further. The six standard voice types each cover roughly two octaves within the full range from bass to soprano.
What are the vocal range names in order from lowest to highest?
From lowest to highest: bass, baritone, tenor, contralto, mezzo-soprano, soprano. The first three are typically male ranges and the last three typically female, though voices vary and can fall between categories.
Can a voice type change over time?
A trained range can extend at both ends with practice, and the voice naturally changes through adolescence and again with age, so a classification made now is a snapshot rather than a permanent label.
