SongMap

A desktop tool for structuring and visualizing song compositions.

SongMap helps musicians and producers map out their tracks section by section — from intro to outro — with real-time BPM-based timing, an interactive timeline, and genre-aware templates. Whether you're writing a pop song or a techno set, SongMap gives you a clear visual blueprint before you touch a DAW.

Usage

1. Pick a genre or artist template from the left panel — this sets a sensible BPM default and a starter section layout
2. Adjust the BPM — all bar durations recalculate live
3. Build your structure — add, rename, resize, and reorder sections using the timeline or the section list on the right
4. Add notes per section for samples, synth ideas, or anything else
5. Save your project as a .json file and reload it later
