The New York Philharmonic is testing a a new handheld device that concert-goers could hold at performances and get real-time narration of the music. “The device will provide a play-by-play analysis of the music as the concertgoer listens. No pictures (so far), only words: the text changes every 15 to 20 seconds. Think sports patter, only highbrow, musical and blessedly mute.”
