Audiences scan the over 40 different QR codes displayed at the venue on their smartphones and play the music track on there.
The shape of the music changes depending on the number of visitors and the timing of playing the track.
 

The QR code includes different sound parts and local soundscapes, and the sound changes depending on the timing or combination and number of people as “Encounter music” for this space.
On the other hand, it is a work that allows making one big music piece by many people accessing different QR codes simultaneously.
This work can be composed in cities around the world using this format.
