Online Vibrato Analysis Tool
Record a vibrato, see its width and speed
Sing a sustained note with vibrato and HengHeng measures its width and rate — turning a mysterious skill into numbers.
How can I tell whether my vibrato is steady?
Record a sustained note with vibrato and check whether width and rate stay even. Vibrato Log turns the feeling into numbers so you can compare stability across sessions.
What this tool is good for
Vibrato is a you-either-have-it-or-can't-explain-it skill. HengHeng records and measures it so you can see how steady and fast yours is.
- See whether vibrato oscillates around a center pitch instead of drifting away.
- Check whether rate, width, and regularity are stable.
- Practice from phrase-ending sustained notes before adding vibrato everywhere.
- Add vibrato only after straight tone is stable so wobble is not mistaken for vibrato.
A 3-minute first drill
Vibrato is not simply shaking. Stabilize the straight tone first, then check for natural movement around a center.
-
1
First sing a 3-second straight tone without vibrato.
-
2
Then let vibrato appear gently in the final 2 seconds.
-
3
Record the take and watch whether width changes unevenly.
-
4
Check whether rate fluctuates and whether the center pitch falls.
-
5
If straight tone is unstable, return to Pitch Monitor and Breath Racer first.
How to read what you see
Rate
There is no single perfect rate; the key is evenness and control.
Width
Too much width can sound out of tune. Start with smaller, stable motion before stylizing.
Center pitch
Vibrato should still orbit the target note, not slide downward or drift away.
Regularity
A natural sound usually comes from a stable but not rigid cycle. If it speeds up and slows down, train straight tone first.
Common mistakes and fixes
Adding vibrato too early
Adding motion to an unstable straight tone makes the issue harder to read.
Shaking jaw or throat
Forced jaw or throat shaking invites tension and transfers poorly into songs.
Using vibrato everywhere
Start at endings and sustained notes; using it everywhere can feel uncontrolled.
Making it too wide
Obvious does not mean musical. Too wide can sound like pitch error.
Pair it with these tools
When you should not keep practicing
Vibrato should not be forced by throat shaking. Stop with fatigue, pain, hoarseness, or obvious jaw/throat tension and return to gentle straight tone.
Questions before you practice
What vibrato rate is good?
There is no one number for everyone. Evenness, natural feel, center pitch, and musical control matter more.
Is wider vibrato better?
No. Too wide can sound out of tune. Start small and stable, then adjust by style.
Why do I go out of tune when I add vibrato?
Usually straight tone, breath, or center pitch is not stable yet. Sing 3 seconds straight, then add vibrato only at the end.
Does no vibrato mean bad singing?
No. Straight tone, pitch, breath, and expression matter too. Vibrato is a style and technique, not the only standard.
Can I practice vibrato every day?
Short daily practice is fine if easy. Confirm straight tone is light and stable before adding vibrato.
