The methods of building instruments vary based on location and time a given instrument was built. So do the materials such as the purfling or finishes.
The first step in restoration is an accurate analysis of the instrument you will work on. One has to try to date back to the maker (if possible), geographical origin and period of construction. Great experience is needed in order to fully evaluate an instrument. I feel fortunate for having the possibility to count on my restoration teacher at the Cremona School Massimo
. It is from him that I have learnt the basics of this delicate art of violin restoration.
