Upload a track and get a colour-coded timeline of its sections — intro, verse, chorus, bridge, outro — with timestamps. Click any block to jump there, or loop one section on repeat. Nothing is uploaded.
How it works
Drag in an MP3 or other audio file. A full studio recording gives the clearest map; a rough demo works too if the parts are distinct.
The tool compares every moment of the song to every other moment, spots where the sound changes, and groups the parts that repeat.
You get a colour-coded timeline labelled intro, verse, chorus, bridge, and outro. Click a block to jump there, or loop one section while you learn or practise it.
Who uses it
Five situations where seeing the sections up front saves a lot of scrubbing back and forth.
The situation: You want to practise the chorus of a song but keep scrubbing past it.
What they do: Map the track, hit Loop on the chorus, and run it until it is under your fingers.
The result: Practice time goes to the hard part instead of hunting for it.
The situation: You are rebuilding a song and need its exact section timings.
What they do: Analyze the original, read the timestamps for each part, and lay out your arrangement to match.
The result: Your version lines up with the original without measuring by ear.
The situation: You want students to hear the difference between verse and chorus in a real track.
What they do: Put the song map on screen and jump between the labelled sections as you explain them.
The result: Students connect the theory to a song they actually know.
The situation: You need to know where the intro and outro sit for a clean transition.
What they do: Map both tracks, note the outro start of one and the intro end of the other, and cue up the blend.
The result: Transitions land on section boundaries instead of mid-phrase.
The situation: You want to understand how your favourite songs are put together.
What they do: Run a few of them through and compare the maps — how long the intro is, when the chorus first hits, whether there is a bridge.
The result: Patterns in the songs you love become obvious once you can see the shape.
FAQ
No. The audio is decoded and analysed entirely in your browser. Nothing is sent to a server, so it is fine to use on unreleased material.
The boundaries — where one part ends and another begins — are usually reliable on songs with clear repetition. The names (verse, chorus, bridge) are a best guess from position and repetition, so treat them as a starting point you can rename in your head.
They mark parts that sound like each other. Every section tagged "A" is musically similar, every "B" is another repeated part, and so on — that is the raw grouping before the human labels are applied.
If two sections share most of their harmony and texture, the tool treats them as the same part. A pre-chorus that is close to the verse, for example, may fold into it.
Yes. Each section in the list has a Loop button that keeps the player repeating that part until you turn it off.
Full songs with a repeating chorus. Ambient pieces, long DJ mixes, and through-composed tracks with no repetition give a much rougher map.
There is no server limit. A normal song analyses in a few seconds; very long files use more memory and take longer.
No — that is what the Chord Detector and BPM & Key Finder are for. This tool is only about where the sections are.
Yes, in a modern mobile browser. The analysis is heavier than a normal page, so a recent phone handles longer songs more comfortably.
Yes, completely, with no account and no limit on how many songs you map.
