Pop the hood on any hit song
The Top40 Theory Timeliner turns a song into a bubble diagram of its sections, phrases and production as it plays. Free for Windows and Mac.

What it is
If you've watched my breakdowns, you've seen these diagrams
With the Timeliner, you can:
- Map a song as it plays: tap B at every boundary you hear.
- Label sections in one click, each with its own color.
- Keep songwriting and production on separate layers.
- Flip between the vocal and the instrumental without losing your place.
- Line everything up with a beat grid, a waveform and snapping.
- Export PDF or SVG files ready for Canva.
- Open your old Variations (.v2t) and Audio Timeliner (.tim) files.
