Why singer vocal ranges differ, and how we handle the evidence
Singer vocal ranges differ between sources because they count different things: written notes in selected songs, isolated live notes across a career, or brief effects. This page explains what our catalog reports, what individual sources can establish, and how to correct the record.
Why do vocal range websites disagree?
Two range charts may be answering different questions. One may list written notes in selected songs; another may include isolated notes from live performances across a career. Neither number alone establishes a comfortable range or definitive voice type. Check what was counted before choosing the larger number.
- Match the version. Are both sources discussing the same recording, live performance, arrangement, and key? One score is not a record of everything its performer has sung.
- Check the note convention. Confirm the octave numbering before comparing endpoints. A note label without its convention can make two claims look farther apart than they are.
- Ask what was counted. Look for distinctions between sustained notes, brief effects, falsetto, and whistle register. Do not silently combine different definitions of range.
- Follow the evidence. A recording and timestamp let another reader check a claim. Repeated charts are not independent verification if they repeat the same unsourced figure.
See the Olivia Rodrigo source review: song-level evidence and disputed voice-type labels are described separately from the catalog's reported range.
Scope of this index
These are approximate catalog reference spans. Most profiles have not had both endpoints individually verified against named recordings or scores. They are not lab measurements or comfortable everyday ranges; use them for comparison, not as training targets.
Source hierarchy
We prefer direct statements, credited scores, documented performances, specialist analysis, and reputable interviews or profiles. A source is shown with the limited claim it supports, rather than being stretched into proof of a singer's whole career.
Song scores have limited scope
A licensed score can document the written compass of one arrangement. It cannot by itself establish a performer's physiological limits, voice type, comfortable range, or career-wide extremes.
Studio, live, and register distinctions
A note captured in a studio, heard in a live performance, sung in whistle register, produced in falsetto, or made with a microphone does not carry the same meaning as a sustained full-voice note. We identify those distinctions when the evidence does.
Disputes, confidence, and human review
Reviewed records name a human dataset editor, a review date, sources, and a confidence level: limited, moderate, or high. A disputed record means the evidence was reviewed and does not support a settled catalog claim. Pending records have not received that individual review.
Reported range is not comfortable tessitura
A reported range may include isolated extremes at either end. Comfortable tessitura is the part of a voice a singer can use repeatedly, musically, and without strain; it is usually narrower and cannot be inferred from a headline range alone.
