The imaginary instrument, made real
What Is an Air Piano?
“Air piano” has always meant pretending to play—fingers drumming on an invisible keyboard, music only in your head. Gesture Synth turns the joke into a real instrument: your webcam watches your hand, and every gesture produces actual sound.
Instead of eighty-eight keys you get four carefully chosen chords per music style, so everything you play harmonizes. You are not faking a piano performance—you are conducting one, with your empty hand as the only equipment.

FAQ
Frequently Asked Questions
Is this a real piano?
It is an air piano in the literal sense: you play by moving your hand through empty air. Instead of 88 keys, one to four raised fingers trigger chords that are designed to always sound good together, so anyone can play something musical in the first minute.
How does the air piano work?
Your browser uses the camera to track your hand locally: the number of raised fingers selects a chord, hand height controls the energy, and a closed fist pauses. No video ever leaves your device.
Do I need to download an app?
No. The air piano runs entirely in your web browser. Open the player, allow camera access when asked, and start playing. There is nothing to install and no account to create.
Can I play without a camera?
Yes. Keyboard mode plays the same chords with the number keys 1–4, Space to pause, and your pointer height to shape energy—useful on devices without a webcam.
Is the air piano free?
Yes. Playing, recording, and downloading your performance are all free, with no account required.
