A faster path from score to practice
If you already have a chart in MuseScore, Sibelius, Finale, or another notation app, you should not need to re-enter the harmony manually just to rehearse it. MusicXML gives you a clean bridge from written chart to practice workflow.
Chord Progressions can import compatible MusicXML files and turn them into a browser-based jazz play-along. Once the chart is loaded, you can change tempo, loop sections, and practice with piano, bass, and drums immediately.
