IT cannot create an art itself I read an article about a startup called Riff Station yesterday. [http://techcrunch.com/2014/07/18/riffstation-play-makes-it-easy-to-play-along-with-youtube-music-videos/] Riff Station analyses YouTube Videos and show guitar chords for you. I think this app is useful somehow. But, I believe music cannot be shown in a bunch of computer programs. Because it's ART. Guitarist always think about the chords and chord degree. But most important thing is tone and touch, and they express their feelings. So, if you really want to play a guitar, you should listen guitarist's tone, and touch and feel their feelings. I do believe IT help make some issues done easy, but IT cannot create an art itself.
