A music game for parties where everyone plays

Instead of fighting over the playlist, the whole room makes the music. Each phone becomes an instrument, one speaker plays it all, and nobody needs to know how to play.

Why it works at a party

• Nothing to install. Guests scan a QR code with their camera and they're in.
• No wrong notes. Easy mode snaps hits to the beat and keeps the keys in one key.
• One sound system. Every phone plays through the same speakers, in time with each other.
• You can see who's playing. Every hit shows on the big screen in that player's colour, with their name.

Ideas for the night

• Build the drop: start with only drums, add the bass after eight bars, then keys, then the effects pad sweeps it all.
• Beat relay: pass the drums from phone to phone every minute. Each player adds one sound to the loop.
• Demo karaoke: start a demo and let everyone play along on top of it.
• The finale: record the best five minutes into a song and play it back at full volume.
