Humidity and Modes

26.07.2016
We have the perfect summer for confirming mode changes. The violins (Soil #1, #2, #3) in 65-70% humidity and 25 C for two weeks. All of them played every day:

Humidity 30-40 % 65-70% 30-40 % 65-70% 30-40 % 65-70%
Weight Weight B1- B1- B+ B1+
Soil #1 404 411 445 439 533 518
Soil #2 402 410 447 441 531 517
Soil #3 397 403 449 443 536 517

Darker, easier to play and very beautiful sound. But they are better soloist violins at winter time (30 - 50% humidity). The change is linear, at least when the plates are made the same weight and M5 frequency (at the same MC% in the wood): Modal goal - Strad average
