This is a broad topic… let me tell you a story.
a) There has been a ton of technological innovation in music: phonograph, recording devices, electric instruments, midi, music synthesis. However all of this still falls under the header of music. There is something very broad about music… and unified. A symphony recorded and played back, a symphony played with an electric violin, with prepared piano, with midi, with a synth, is still a symphony.
2) There has also been a ton of technological innovation in the visual arts: the photograph, different printmaking technologies (silk screening), filmmaking, animation, compositing. But this this does not fall under the header of painting. A photograph of a painting is a photograph, a recording of a symphony is a symphony. Why is that?
