Vocal Range, Tessitura, and Voice Type

What a Vocal Range Test Measures

Many tools reduce a vocal range test to the lowest and highest notes. Those notes are useful, but they are not the whole story.

Vocal range is the span of pitches you can produce. Tessitura is the part of that range that feels comfortable and repeatable in music. For choosing songs, tessitura often matters more than a single extreme note.

Oniki Check focuses on your detected lowest and highest notes. That is a useful starting point, but when choosing songs, prioritize the notes you can repeat without strain inside that range.

Do Not Classify Voice Type From Extremes Alone

Bass, baritone, tenor, alto, mezzo-soprano, and soprano labels are useful, but a highest note alone cannot decide your voice type.

If you can touch a high note once but cannot sing phrases there, that note should not be the main basis for choosing a key. A stable middle range can be far more important.

Track Chest Voice and Head Voice Separately

The same vocal range test changes depending on whether you include falsetto or head voice.

• Chest voice: closer to speaking voice and often clearer for lyrics.
• Head voice: easier for higher notes, but tone and volume may change.
• Mix: the coordinated area between registers.

For practical notes, write results like "E3 to G4 in chest voice" and "E3 to C5 including head voice."

How to Use the Result

Your measured range can help with karaoke keys, practice notes, and song selection. If a song's highest note is exactly at your tested limit, it may still be too hard in context. The karaoke key guide recommends keeping two or three semitones of margin.

Watch the Trend

Range changes with sleep, warmups, health, and practice. Repeating the test under similar conditions tells you more than a single number.
