SOME FASCINATING FIGURES TO HAND
Having just marvelled at the Prom performance of Rachmaninov's 3rd Piano Concerto by Alexander Gavrylyuk, the topic of 'hands' is on my mind. His digits were an absolute blur, so I logged on to find out how fast fingers can move. I've not found an answer to that particular question, but I have stumbled upon several other amazing facts:
The Fibonacci sequence (see my post of 28th June 2017) dictates the length of our metacarpal bones. Their proportions are 2 3 5 8, which allows the formation of a fist in a spiral. I just checked and yes, the side view of my fist is like a snail shell, another wonder of creation which uses Fibonacci's sequence.
There are no muscles in our fingers. Astounding, isn't it? The muscles which control our digits are in the palms and lower arm, just connected to our fingers by tendons, like the strings on a puppet.
The palm of our hands has been designed so the skin can't roll over the surface of the bones, but stays still even if we're wringing out a cloth etc.
Soak your hand long enough and the palm wrinkles. (I believe that's the only part of the body where this happens. Or maybe it applies to the feet too? I shall have to have a nice long soak and check). But if the nerve to the palm is cut, the wrinkling no longer happens. So it's a nerve thing. How odd...
The brain controls the whole body, of course, but the articulation of the hands accounts for a whacking great 25% of the brain power required for movement anywhere in the body.
Bringing us back to Rachmaninov, his hands were so ginormous that he could span middle C to the A over an octave above!!

I have decided I must part with my spare organ. We live in such a tiny house now that there's no room for sentiment - hardly room for a shoe horn come to that. If you would love to own one of these delicious instruments, without the cost and bother of importing it yourself, drop me a line for further details.
