Follow intonation continuously instead of waiting for a single note readout.
Pitch monitor
Live pitch monitor for voice and instruments
Use Fiume when you need more than a tuner needle. It shows the pitch path in real time, so you can see drift, stability, slides, and vibrato while you sing or play.
Free to try in your browser. Microphone permission only when you start listening.
Works well when the pitch path matters more than a simple in-tune or out-of-tune check.
No install, no signup wall, and no setup beyond granting mic access.
Helpful during repetition, warmups, long tones, phrase work, and lesson feedback.
Why use a pitch monitor
Notice what a basic tuner often hides
A standard tuner is useful for quick center checks. A pitch monitor is better when you need to see how the note arrives, settles, drifts, or oscillates over time.
See the full line
Watch how the pitch behaves across the note instead of reducing the whole event to one label.
Catch instability earlier
Drifting sustains, overshooting entries, and uneven vibrato become visible before they turn into repeated habits.
Keep practice moving
Open it quickly between repetitions, make one adjustment, and run the phrase again without changing tools.
When it helps
Common practice moments for a live pitch monitor
Fiume is most useful when you care about how intonation behaves across time, not only whether a target note was roughly correct.
-
Long tones See whether a note settles cleanly or keeps drifting after the attack.
-
Phrase entries and endings Catch notes that start high, land late, or sag at the end of a line.
-
Slides and portamento See the path into the target instead of guessing whether the arrival was clean.
-
Vibrato shape Watch whether the oscillation stays even, centered, and controlled.
-
Teacher and student work Share one visual reference while discussing what changed between repetitions.
-
Instrument intonation checks Useful for winds, brass, strings, and any single-line instrument where pitch path matters.
FAQ
Questions people ask before trying a pitch monitor
Is this different from a tuner?
Yes. A tuner is usually optimized for fast center checks. Fiume also shows the contour, so you can see drift, slides, and vibrato across time.
Does it work for singers and instruments?
Yes. It is most useful for voice and single-line instruments where one main pitch is being tracked at a time.
Do I need an account?
No. You can open the app and start the live monitor without creating an account first.
Which browsers work best?
Use a recent browser with microphone, WebGL, and audio support. That gives the smoothest live monitoring experience.
Open the pitch monitor and test one phrase
Start with a sustained note or one short phrase and watch what changes from repetition to repetition.
