Musique concrète

A man walks down the sidewalk towards the Vienna Stadthalle, reading a Kriminalroman by Alex Beer, “Der zweite Reiter.”
Suddenly there is a big KADONGGG!!
And the man sees a few stars.
What a beautiful new sound, the man thinks.
KADONGGG, I love it.
He rubs his head. He focuses his eyes on the steel pole of a street sign, very close.
He steps around the pole, finds his place in the book, and continues walking, half of him reading, half thinking about the sound.
Half of him wondering how a Foley artist would reproduce it, the THONK of brain against skull against 4-inch steel pole, the ringing tintinabulation of the pole and the sign after being struck.
KADONGGG!
The world is full of beauty.
