Secrets of Stradivarius Explained | Wired Science from Wired.com
In a study published yesterday in Public Library of Science ONE, Dutch researchers ran five of the peerless instruments, made in the early 18th century by Italian craftsman Antonio Stradivari and synonymous with harmonic perfection, through a CT scanner.

The resulting three-dimensional X-rays revealed that wood used in Stradivari’s violins possessed an exceptionally uniform density, with little variation in growth rings added by trees each season.

Summertime growth typically outpaces wintertime growth, producing broad rings of relatively permeable wood that alternate with narrow, dense winter bands. That differential affects the wood’s harmonic qualities.

Fortunately for Stradivari, he lived during the Little Ice Age: trees grew little more in summer than in winter. Hence the uniformly dense wood, hence three centuries of experts baffled by the resonance of Stradivarius violins, which have been variously attributed to varnishes, boiling and submersion in ponds.
