An interesting question: what happens if you put 14 acoustic guitars on the floor and play them randomly? You would assume it would result in uninteresting noise, but listening to Playa by Ruben Dhers proofs the result can also be quite enchanting. 31 DC motors play the guitars using fans, and a computer controls the installation. The speed of the fans varies, causing a pleasant change in dynamics, and when they swing back and forth a higher speeds it feels like we’re listening to waves of guitar strings.
Playa can be seen in real life at the Neues Museum Weimar, Germany.
