I have seen the Kimball slow motion film. It is very dramatic. I was disappointed, though, that the string was not at normal tension. I guess that would not have been dramatic enough, so they slackened the string for the film. I would like to see a film of a bass string at normal tension so I could see what happens in a real piano.
