Research
Everything we publish here comes from measurement rather than teaching tradition: guided range tests, the vocal lines of songs people uploaded to learn, and scored practice attempts, all recorded by PitchHighway’s own pitch pipeline. Every figure is an aggregate — none describes an individual person or performance — internal and test accounts are excluded throughout, and each study carries its own snapshot date.

Across 710 upload transcriptions, 64.6% placed at least 90% of modeled sung duration inside one octave. Only 9.9% kept their entire range there. What range endpoints leave out.

Across 632 measured voices the median range spans 23 semitones (D3–C#5); the median uploaded song’s vocal line spans 20 semitones; and singers who repeat a song gain a median +39% between first and best attempt on that song.
