Evolutionarily speaking...
What I REALLY don't get, is the usefulness, evolutionarily speaking, of some things. Music preference being one such thing. If you subscribe to the Bollywood school of thought, music is integral to the mate selection process. You roam the alleyways, woods (running round trees is a great catalyst), shopping malls hoping to hear the tune you're humming, sung back to you with a complete orchestra and about fifty dancers. If you do, you know you've found your partner to further the species with.
Jokes apart, what role does music have in our lives? I read a Readers Digest piece long ago called "Life's little extras" and the author had listed music, flowers, and other soppy stuff as not really being required, but as enriching our life. Well, cynical old me found a use for all those things (circle of life, if nothing else) except for music. Of course, music has therapeutic and calming, and sometimes cathartic effects, but stone age man didn't need Beethoven or Dave Mathews to calm him down or Kurt Cobain to express his angst. I don't know why and how music became such an integral part of human beings' existence. Anyone who has tried learning the theory behind Carnatic music, or tried reading orchestra music, or tried teaching a kindergarten class to sing in a co-ordinated chorus knows the crazy complex world that is music. I don't know a single person who doesn't like some kind of music. The question is never, "Do you like music?" It's always, "What kind of music do you like?"
I am not complaining, just curious...why do we need music? (Btw, here's a teaser - if anyone has read Isaac Asimov's "Jokester" they'll know what I'm worried about, as I ask this question! If you have read it, pleasssssse post a reply. If you haven't, pleassssssse read it!)
