F1, F2, and F3
F1, F2, and F3 are candidate resonance peaks. They can move when the jaw, tongue, lips, and vowel shape change.

Formant analyzer for vowel and resonance practice
Formants are one of the most useful ideas for singers who want to understand why a vowel feels easy on one note and difficult on another.
Vowel modification
On higher notes, a small vowel change can move a formant candidate away from or toward a harmonic. That can change how the note feels and how it projects.
Formants are candidates
Real-time browser estimation is not a laboratory vowel study. Use the values as practice clues and compare repeated takes.
Useful experiment
Sing one pitch on AH, EH, EE, OH, and OO. Capture each vowel and compare how F1 and F2 candidates move.
Frequently asked questions
Are formant values exact?
No. They are real-time candidates affected by microphone, room, pitch, vowel, and signal quality.
Which formant matters most?
It depends on the vowel and pitch. F1 and F2 are often the easiest to observe during vowel changes.
Can formants explain high notes?
They can help explain part of the experience, especially vowel adjustment, but they are not the whole technique.
