Built for harmonic digging
The global archive is strongest when you use it as a pattern library, not as a perfect discography. Start with genre and decade lanes, listen for movement, then pull MIDI into the DAW and reshape from there.
Immediate DAW handoff
Every progression can turn into MIDI immediately, so the archive behaves more like a working sketchbook than a static reference page.
Pattern-first analysis
Read the harmony through chord shapes, Roman numerals, key center, and era context instead of depending on inconsistent track naming.
