+ Start a jam

Make songs with strangers

Drop an audio clip. Strangers stack their instruments on it.

How it works
  1. 1

    Upload an audio clip

    A riff, a beat, a vocal line. Ten seconds is enough. Its tempo, key and length become the starting point for everyone.

  2. 2

    Strangers will stack their instrument on top

    Every take is played on top of the ones before it, so each reply becomes its own stack. Join in wherever you want.

  3. 3

    You shape the song

    Mix the best takes into one song. And every stack that grew along the way stays, for you and everyone to enjoy.

A riff, a groove, a vocal line, a beat. Ten seconds is enough.

Start with any instrument. Others stack the rest.
