star sounds

John Cage wrote several sonatas based on the placement of stars in the sky. He used sections of starcharts to transpose the locations of certain stars to their equivalent on a music staff. My idea for this project is similar— taking a random image of stars to play a note corresponding to the individual locations (and brightness) of stars on screen. Originally built using Processing, later ported to the web with p5.js.

Make your own music from the stars here!


Hit any key to reveal some stars. Click a star to play a note. Hit any key to play a different space. If no sound plays, try using a different browser. Firefox seems to work best, chrome seems to have issues with p5.sound.js.
