Violins of Scandinavian spruces?

Postby taxelson » 09 Jan 2009, 21:42

I have asked a question to some people knowing a lot about violins, if there are any violins made of svandinavian spruce-wood. The common (and surely the right) answer is that according to tradition also Swedish instruments are made of central European wood, at least high quality instruments. It would still be interesting to see measurements from instruments used by ordinary people in the countryside. I think they often not had the recourses to bye expensive instruments from abroad or by professional luthiers, but they often were very skilled in ordinary wooden handcraft, and probably able to build their own instruments, although they did not made any masterpieces.

Bertil Israels, dendrochronologist as well, measured the top of two instruments from around Svärdsjö in Dalarna. One of them, an instrument used by a man in the village Marnäs in Enviken (60º50'13"N, 15º39'53"E), dead around 1950, seems to be made of rater local spruce wood after 1924 (Marn01) and the other one of imported (south-german?) wood after 1961 (Eost01). I hope Bertil will write a report and link to it in a reply. Below are correlation values and the mean value series (rwl) so far. Hopefully we may be able to study some more instruments.
