Today's riff

A fresh generated track every day. Same one for everybody.

One track a day, generated fresh at midnight UTC — a different genre, key and arrangement every time, and the same one for everybody. Play it, learn it by ear, or open it in the Studio and pull it apart. Tomorrow's will be somewhere else entirely.

  • bass
  • pad
  • melody

Same riff for everyone, everywhere, until midnight UTC. Open it in the Studio to take it apart, change the key, swap an instrument — or just play along on anything in the collection.

What to do with it

  • Play along. The key and tempo are printed on the panel. Open any instrument in another tab and find the notes by ear — that is the whole exercise.
  • Take it apart. Open it in the Studio and mute tracks one at a time to hear what each one was doing. A bassline alone is a different animal.
  • Make it yours. Change the key, swap the drum kit, throw away the melody and write your own over the chords. Nothing here is precious — there is another one tomorrow.

Where it comes from

The same generator that powers the generator page: a genre picks its drum kit, its bass and chord styles and its scale, and a seeded roll arranges eight to sixteen bars with an intro, a lift and an ending. The only difference is the seed — instead of rolling a random one, the daily riff derives it from the date, so it is identical for every visitor and reproducible forever. Ask for a particular day and you will always get that day's music back.

Want a different one right now?

That is what the generator is for — roll as many as you like, in any genre and key, and describe a mood in words if you would rather not choose. The daily riff is the opposite idea: one track, no choices, the same for everyone, gone tomorrow.
