Where music becomes code and, line by line, code becomes music — children make art, and perform what they made.

SonicLoop™ is a music and creativity program built on Sonic Pi — a free, open-source live-coding tool made at the University of Cambridge. Children ages 9 to 13 write their own music as code, a line at a time, and on the final day they perform it.

It’s an Arts Integration program — that’s the (AI) in our name. Arts Integration (Kennedy Center; NAEA) means two subjects taught as one, where you build understanding of each through the other — not side by side, but inseparable. And the integration isn’t done by us, in the lesson plan — the child is the integrator. Every choice a child makes is musical and computational at the same moment; holding both at once is the skill, and it’s theirs.

Here’s what that looks like: a child types play 60 and a note sounds. That single act is both things at once — a line of code and a musical choice (middle C, the home note). To write the next line they have to think musically; to hear their musical idea they have to write it correctly as code. The music can’t happen without the code; the code is silent until it’s music.

And the music has a real backbone. Across the week, children start in one key — a home the ear learns to recognize — travel out to the chords around it and come back, then discover a second home, a minor one, built from the very same notes but bright turned to shadow. They feel how harmony actually works before anyone names it for them. Hear it first; read it after.

We built this for a particular moment. As more and more is made instantly — by machines, for us — the thing children most need is to make something real, slowly, with their own hands. Not music made for them. Music they make.
