The soundpost patch
This restoration work requires prior preparation of a mould.
The soundpost patch is a piece of spruce (front) or maple (back), which is fitted when the instrument is injured in this fragile area.
After opening the instrument, the violin maker hollows the arching from the inside, leaving less than one millimetre of thickness to the varnish, and adjusts a new oval piece with great accuracy. Most antique instruments are broken in this area. This depreciates their value, but restoration work which is performed correctly does not affect the acoustic quality of the instrument.
