The Philadelphia Orchestra recently released a new interactive app that allows audiences to learn more about the performance they're experiencing as they experience it. While mobile phones are typically discouraged during a show, in Philly things are different.
The LiveNote app works a bit like a digital program that you would typically receive at a performance. In addition to information about the concert, the performers and historical context, LiveNote also offers relevant information about the piece. This real-time content delivery is possible thanks to technology similar to Shazam. LiveNote is able to recognize where you are in the piece and informs the Philadelphia Orchestra audience with highlights and commentary on the music. The interactive app also gives text translations and story guides.
