Particles AR vs AirViolin

Discover musical structures in a playful way—without reading music—and experience music in a new, synesthetic, immersive way.

Turn your iPhone into a motion-controlled violin. Imagine you are holding a violin, and move your phone as if it were the bow. Air Violin transforms your device into a musical instrument using only built-in motion sensors—no strings, buttons, or external hardware required. How it works • Tilt your phone forward and backward to select notes • Pitch angle determines which violin note is played • Move your arm to simulate bowing • Faster movement produces louder sound • Stop moving to stop the sound instantly A visual angle guide shows where each note lies, helping you understand how pitch maps to motion in real time. Expressive and intuitive Air Violin is designed to feel natural. Sound reacts instantly to your movements, allowing dynamic control similar to real violin bowing. Volume scales non-linearly with motion speed, so gentle movements sound soft while faster strokes become more powerful. Features • Motion-based violin playing • Pitch-to-note mapping with visual feedback • Dynamic volume controlled by movement speed • Clean, minimal interface • No external instruments or accessories required • Uses native Apple motion and audio frameworks Use cases • Musical experimentation • Creative play and exploration • Learning pitch awareness through movement • Casual performance and sound design Air Violin processes all motion and audio locally on your device and does not collect personal data. Pick up your phone, move your arm, and play.
