Why not just buy a Steinway? LOL! That looks like a tricky little set of steps to remember without a road map. I know, I can always refer to the video again... but I suspect there may be a step or two missing or over-simplified. Then there is the "warranty thing" 'cause I believe it (the law) is much more favorible to the manufacturer than the buyer/owner over here in "The States!"
Interesting to watch, though! Thanks for sharing.
Do your best to be invisible... and kind.
