Why this workflow matters
When you are learning a jazz standard, the bottleneck is often not the tune itself. It is the setup around it: finding a usable track, checking the key, adapting the tempo, and restarting every time you want to isolate a section. Practicing online should feel much lighter than that.
Chord Progressions gives you a browser-based jazz play-along with a built-in library of standards and exercises. Choose a tune, adjust the tempo, set the drum feel, loop a form, and keep working without leaving the player.
