What is Jam?

Jam is a practice studio for musicians. Add a song and Jam splits it into parts, writes out its chords and lyrics, and lets you slow it down, loop it and record over it.

Jam runs in your web browser, so there is nothing to install. Open Jam (opens Jam in a new tab) in any modern browser.

What Jam does with a song

When you add a recording, Jam:

  • separates it into six parts: vocals, drums, bass, guitar, piano and other (how separation works);
  • finds the beat and the chords, and transcribes the lyrics in time with the music;
  • opens it in the Studio, where you mix the parts, change the speed and key, loop passages and record your own takes.

What you need

  • A free account to add your own songs. You can play the demo songs and open sessions other people share with you without one.
  • Audio or video files you have the right to use. Jam adds songs from files on your device; see supported files and limits.

What Jam isn’t

  • Not a music catalogue. Jam doesn’t stream or sell music, and it can’t import from streaming services (why).
  • Not always right. Separation, chords and lyrics are produced automatically and can contain mistakes. Your ears have the final word (when Jam gets it wrong).
