Maestro

Best Musical Hack (378 teams)

TreeHacks · 2026

Point a camera at a broom and play it like a real guitar. It tracks your hands and turns air-strumming into actual notes and chords, and whatever you play can grow into a fully produced song.

We’re an international team, and music is one of the few languages everyone on our team shares. No matter where we’re from, we’ve all used everyday objects, desks, bottles, and brooms to make rhythm or pretend instruments. We wanted to build something that lets anyone express themselves musically and develop their musical skills without needing expensive gear or formal training. Maestro turns a broom into a playable guitar and music studio. Using a camera, hand tracking, and sound mapping, we detect a broom and map your hand movements to musical notes so you can instantly play it like a real instrument. An iPhone companion detects pressed “strings,” letting you form chords and control pitch while strumming in the air.
