jazz is about playing notes from your soul
it's about agreeing with yourself, or however many other musicians are with you at the time, on a certain specific outlook on life at that very moment
wiimusic is about waving a piece of plastic around and having random notes that are in the right key come out
there is much more that a (worthwhile) musician puts into each note they play than simply knowing that it's in the right key, and randomly playing applicable notes.
Wii music bothers me because, I don't think it brings music to the masses, if anything, it does the opposite, making it even more difficult for people to find music as an outlet in there lives. It gives people the wrong idea about music. It makes music become a science, where the correct output is just any note that's in the right key.
The beauty of music, or any art, is creativity, and Wii Music does not offer that to players. Not that Guitar Hero does (previous installments at least, the new one coming out on the other hand...) But anyways, when people tell me that guitar hero is great and wii music is great because its exposing more people to music and getting people to start taking lessons or whatever, you know that's great, if you want to go learn how to play freebird and stairway to heaven, and can play them at parties for people, that's great, but I'd think it's truly great if you can pick up a guitar or any other instrument, and say something interesting, say something i've never heard before, tell me how you feel. I'd be glad to listen if you have something to say.
