  1. I think bridge functions as a modulator that adds its own "colors" , modal vibrations, to the content of string vibrations. Adjusting the local stiffness of various part of the bridge will change the modal characteristics of the bridge, and therefore colors the string vibrations differently that been transmitted.

  4. Hi all, I wasn't able to copy and paste a link to a research paper written by Eric Fouilhe in 2013. The title is String "After-Length" and the Cello Tailpiece: Acoustics and Perceptions. Please do a google search of " Eric Fouilhe, Tailpiece" and it will show up first.
  5. 24 frames per second to make a movie like video. 1/4000 second per exposure to capture the instataneous wavy displacement of the vibrating 2string. So the movie is like a interpolation of many 1/4000 second events captured every 1/24 second.

    Thank you Stephen. It was maple syrup that I used. Cooked and diluted it with warm water as Jezzupe described. Before applying the sugar water, I damped the white violin, raised the grain, and lightly scraped or sanded twice. Two coats of sugar water applied consecutively. Then followed by three coats of diluted shellac and then finished with oil varnish.
