Footprints
Find the same phrase in different jazz solos, hear both, and see the notes line up.
Live: https://dsleo.github.io/jazz-footprints/
The archive covers 1,558 transcribed solos (456 horn solos from the Weimar Jazz Database, 1,102 piano-trio solos from the Jazz Trio Database) and about 323,000 matching passages. Everything is precomputed, so the site is plain static files.
- Crate: browse matching pairs, filter by decade, instrument or musician.
- Pair view: score excerpts, MIDI playback and links to the recordings.
- Echoes: a timeline of musicians and their strongest connections.
- Listen & Find: record or upload a line and search the horn solos, all in the browser.
- Who echoes whom: a short tour of whose phrases come back most.
A match means similar notes, not proof of borrowing.
Run it
python3 -m http.server 8766 -d static # then open http://127.0.0.1:8766
It needs a server; opening the files directly does not work.
Rebuild the data
python3 -m jazzmine download # WJazzD -> data/wjazzd.db
python3 -m jazzmine sync-jazztube # recording links
python3 -m jazzmine import-jtd-pilot JTD.zip --limit 1294
python3 -m jazzmine.video_audit # drop unavailable videos
python3 -m jazzmine.artwork # album covers
python3 -m jazzmine.joint_store # search, about a minute
python3 -m jazzmine.static_export # -> static/catalog/
python3 -m jazzmine.quotation_stats # -> static/stats.json
npm ci && npm run build:listen # local pitch model
python3 -m jazzmine.listen_export # -> static/catalog/listen/
data/*.db stays local; static/catalog/ is the committed output. Pushing to main runs the tests and publishes static/ to GitHub Pages.
Test
python3 -m pytest -q tests/listen tests/test_joint_search.py tests/test_static_export.py tests/test_dtl_export.py
npm run test:listen:unit
npx playwright test
