Not just Five Lectures, but also the excellent high speed videography of Stephen Birkett, which makes the theoretical writings visible. The video he posted of the close up of the Wapin pin is particularly vivid, showing the "shivering" of the wire at the pin - the various partials activating it. The bass string videos are also quite helpful for getting the message that this is, indeed, what happens: a wave propagating from the hammer blow and reflecting back and forth.
