Sonic Pi was specfically designed for and built in collaboration with teachers for use in the classroom.

Music Live Coding

Sonic Pi has been extended from a focus on Computing to Music Live Coding. We have also developed a scheme of work specifically for the Music curriculum.

Simple & Fun Computing

Sonic Pi comes with a scheme of work targetted for KS3 Computing developed in harmony with the new UK curriculum.

Designed for Teachers

Sonic Pi was designed, implemented and developed with extensive classroom trials in close collaboration with teachers. Sonic Pi is therefore ready for your classroom.

Live Coding Performances

Sonic Pi is a new kind of musical instrument.
Watch how you can use it for live performances from ambient sets to Algoraves in nightclubs...

Free Book

Sam Aaron, creator of Sonic Pi, has written this book to
complement the built-in documentation.

Master live loops, code drum breaks, compose your own melodies make random riffs and loops, learn to shape and sculpt sounds and much, much more...

Music. Code. Simple.

See how easy it is to get started coding your first sounds...
