I don’t think most people think about definitions of music at all, to any degree.
Most people simply react to music, as music. I believe this largely happens in a pre-conscious manner, and I also believe it’s likely that it happens for people in a much broader way than they’d be likely to consciously identify as such.
We are constantly reacting to the rhythms of our days. The tune of our environment. We must, as it is part of our survival instinct.
So, I’m suggesting that we brainy monkeys are rather fond of ascribing things to our neocortex, and while it’s true that it’s possible for music to be quite cerebral, I am asserting that it needn’t be. That in fact, it needn’t be conscious at all.
