QR codes are ubiquitous, but consumers generally disregard them because they can be a nuisance to scan, and generally contain little useful information. They have multiple other uses for shipping, logistics, and ticketing, but at a "consumer" level, they're typically used to trigger URLs and strings of text. As part of my initial thesis exploration, I reframed the QR code to push its potential: I took sets of QR codes and turned them into a musical instrument.
QRchestra is an app that scans each unique code and uses it to trigger a sound effect. When played in succession, the codes are able to produce an orchestral piece.
You can experience QRchestra yourself—as it is now available on the Apple App Store as a free download—and scan the codes below to try it!
