Outcome

The Bridge uses Android Things to power the interaction and connectivity of musical devices placed at street level and within the bridge. Artists, creatives, and all passersby are welcome to use the devices (which use interfaces inspired by the Music Lab Chrome Experiments) to create the ambient soundscape within the bridge. Passersby in the bridge can use the path they travel as a passive way to provide feedback to the soundscape they hear. Creators on street level can also see their rhythms manifest and resultant feedback as a light show on the bridge (since sound will not work at this scale).

We'll use physical instantiations of some of the clever musical "instruments" from Google Chrome Experiments

There is a subtle communication strategy in the act of creating this music. Tension and dissonance will arise—it could be intentional, an tiny act of protest, or just poor musicianship—and can be resolved by other participants. Back and forth, call and response, patterns like jazz (which is a nod to Pittsburgh’s Hill District rich history of jazz musicianship).

A Bill of Materials

"Instruments" based on Chrome Experiments (physical instantiations using some form of Arduino or Raspberry Pis as the microcontroller)

Media Server to receive input from "instruments" and synthesize soundscape

Speakers (playing sound directly from synthesizer running on media server)

Lighting (on dimmers, with controllers connected to media server)
