Each and every note of this Bach classic is in the exact right place. Perfect.
There’s nothing quite so satisfying as seeing something performing its one function with utter perfection.
Equally, the music of Bach is a mathematically precise and perfect expression of the very same thing, but in music.
Can you see where we’re going with this? Here’s a superb contraption that plays a Bach superhit just by sticking a golf ball in the top. Magic. (And a very well-deserved round of applause at the end.)
