Very cool footage if you are interested in how string instruments work. This is straight video, unaltered and not CGI: The interaction of the digital video camera light-sensor’s scanning speed, the frequency of the string, and the frame-rate of the video make the standing s-wave in the bass string visible. (This is called a “rolling shutter” effect, and there are lots of cool examples floating around the internet. Wicked-awesome!)
