Follow the note center of a voice, riff, bass line, horn line, or any clear single-note part.
Online music analyzer
See the notes and chords in live music
Use your microphone to turn sound into a live visual readout. Fiume follows melody notes, pitch movement, and chord names as music happens, so you can understand what you are hearing without leaving the browser.
Free in your browser. Microphone permission only when you start listening.
Switch to chord mode and see common major, minor, seventh, sus, and slash chords from live audio.
See slides, drift, vibrato, and the way a note settles instead of reading only a static note label.
Live analysis runs in the browser. No account, no install, no upload for real-time listening.
What it can analyze
A live view of the musical information your ear is chasing
The goal is not to replace listening. It is to give your ear a visual partner when you are figuring out what is happening in a song, a lesson, or a practice room.
Notes and melody lines
Sing or play a line and watch the note centers appear as the contour moves. Useful for melodies, solos, bass lines, and vocal phrases.
Chords and voicings
Strum guitar, hold piano chords, or play ukulele voicings and read the likely chord name in real time.
Motion over time
Watch whether a note starts sharp, slides into place, drifts flat, or carries vibrato. That shape is often more useful than the note name alone.
How it works
Point the microphone at the music and choose the view you need
Use a clear source when possible: your instrument, your voice, a lesson example, or a recording played close enough for the mic to hear.
01
Allow the mic
Fiume listens only after you start the analyzer. Use your built-in mic or an audio interface.
02
Pick notes or chords
Use pitch view for melody and single-note lines. Use chord/poly view when the sound has harmony.
03
Watch the music live
Follow the visual trace while the sound is happening. Pause, replay, slow down, or practice the passage again.
Use cases
Helpful when your ear has the idea but wants confirmation
Learn a melody by ear
Follow the note center of a vocal line or instrumental phrase and use the contour to find where it moves.
Check the chord you are hearing
Play along with a recording or test a voicing on your instrument. If the harmony is clear, the chord name gives you a faster starting point.
Understand why a phrase feels unstable
See whether the issue is the attack, the landing, the sustain, or the vibrato shape instead of guessing from memory.
Honest limits
Made for live analysis, not magic transcription
A useful music analyzer should say what it can and cannot do. Fiume is strong when the microphone hears a clear musical source. Full commercial mixes with drums, vocals, bass, and layered instruments are naturally harder.
Not a stem separator
It does not isolate every instrument in a finished mix. It analyzes the audio it can hear as one live signal.
Not automatic sheet music
It helps you identify notes, movement, and chords. It does not export a complete written score.
Better with clean input
Quiet rooms, direct instruments, and simple arrangements produce clearer readings than noisy rooms or dense recordings.
FAQ
Questions about the online music analyzer
Can I analyze a song playing from speakers?
Yes, if your microphone can hear it clearly. Simple passages, isolated instruments, and clean recordings work best. Dense full mixes can be harder.
Does it detect both notes and chords?
Yes. Use single-note pitch monitoring for melody and voice, or chord/polyphonic mode for guitar, piano, ukulele, and other harmony instruments.
Is this the same as a tuner?
No. A tuner answers whether one note is sharp or flat. A music analyzer shows more context: note movement, melodic contour, and chord names when there is harmony.
Does my audio get uploaded?
Live analysis runs in your browser. Fiume asks for microphone permission only when you start listening.
