You have found the Strudel REPL, a live coding platform to write dynamic music pieces in your browser! Strudel is a JavaScript version of TidalCycles, which is a popular live coding language for music, written in Haskell. It is free and open-source and made for beginners and experts alike.

Try changing the code of my WIP!

First Steps:

• setCpm (cycles per minute) to change the speed
• set const SCALE to "g4:minor" or "a3:mixolydian"
• line 144: change the LOOP_LENGTH (in cycles)


• sound patterns are highlighted when active
• try changing them to see which patterns represent each instrument


• lastly: just play around and have fun :)
