The Soundpost in the Violin:
an update
It was thought that a “support” post was first fitted in a central position and a connection made with the “pin hole” found in the back of some instruments but this does not seem to be valid.
It is not known when the soundpost was moved to its present position behind the treble foot of the bridge but musicians were very innovative at the time as indicated by the varying positions of the bridge.
This is a highly scientific article from UNSW and is tough going but a great read about a tiny piece of dowel and how important it is to stringed instruments….
