Yes it is really beautiful. I wonder how the player knows where to place his bow? Unless the saw has marks on it to remind him?
It's a far cry from those elastic band instruments I used to make when I was a kid. I'd hammer nails in a block of wood and stretch elastic bands over them, then pluck them to make a sound. The trouble was, they had to be very tight and often snapped. That wasn't what you'd call a beautiful sound...but worth an experiment. My Dad then made a block of wood with a hole in the middle for me to try, which improved things a bit! haha!
