The musical scale was divided (in Western culture) into twelve notes - don't ask me when; I forget. But it was a long, long time ago in a kingdom far, far away. Other cultures have divided the musical scale into 5, such as the pentatonic Asian system, or twenty or more such as in India and the Near East. Twelve divisions seems like a very wise number to me because it is the smallest number with the most divisors. Twelve is a mathematically rich number and in music, this leads to many interesting harmonics. To a Westerner, the twleve-tone scale seems almost programmed by nature into the brain's neural circuitry. But this is not so.
I've always wondered why there IS something such as music at all. And why do people seem to respond in identical ways to it? Why do some people have perfect pitch? And are there people in other cultures that have perfect pitch for a musical scale with thirty notes? Are there musical intervals in a thirty-note scale that express melancholy, weirdness or a sense of incompleteness that everyone in that culture recognizes? Hmm.
Caveman Crooners May Have Aided Early Human Life
$this->bbcode_second_pass_quote('WSJ', 'M')ore evidence that the brain has dedicated, inborn musical circuits is that even babies have musical preferences, finds Sandra Trehub of the University of Toronto. They listen longer to perfect fifths and perfect fourths, and look pained by minor thirds.
If music is indeed an innate, stand-alone adaptation, then evolution could have nursed it along over the eons only if it helped early humans survive. It did so, Prof. Mithen suggests, because "if music is about anything, it is about expressing and inducing emotion."
Particular notes elicit the same emotions from most people, regardless of culture, studies suggest. A major third (prominent in Beethoven's "Ode to Joy") sounds happy; a minor third (as in the gloomy first movements of Mahler's Fifth) provokes feelings of sadness and even doom. A major seventh expresses aspiration. The absence of a third seems unresolved, loose, as if hanging, adds jazz guitarist Michael Rood, 17 years old.
