PMK, read my post slooowly, now we're well into the new year
Yeah, you're right. Makes loads more sense that way.
But little did I know that pianos had cast iron metalwork in them. For some reason I just assumed that all pianos frames were wood, wood and more wood. I guess even wood expands and contracts, but it never occured that you'd need a heater in there. On reflection it makes perfect sense. Thanks for the heads-up.
Pianos are great instruments. And what REALLY fascinates me is how you play them. I mean, you have BOTH hands dancing up and down all over the keys. How do you DO that? Guitars are dead easy in comparison, so anyone who plays piano is a genius in my book. Sticking me in front of a piano is akin to sticking a computer keyboard in front of a monkey. I can just about find my way around middle C, but that's as far as it goes. You guys that use BOTH hands while tickling them ivories, making all them harmonies.......... Like I said, pure genius.
Pse 'scuse my ignorance regarding that heater scene.
By the by, I recall some old gadgy coming to our infant school to tune the hall piano. I seem to remember him spending AGES on getting it right. Was only 5-yrs-old at the time, and the first time I'd seen the innards of a piano. 'Twas an all-wood job. I don't recall seeing any piano heater, but that school hall was bloody freezing in the winter.
