The Loh Down On ScienceNot all violins are created equal, but don’t get strung out!This is Sandra Tsing Loh with the Loh Down on Science.For two centuries, the Stradivarius has been the best violin money can buy!They were built by Antonio Stradivari, of Cremona, Italy, in the seventeenth century. His violins have brilliance, and they project a distinct, clean sound. Interestingly, no other luthier has been able to replicate the Stradivari magic.What makes his sound so unique? Chemists at the National Taiwan University wondered. They analyzed and compared the maple wood used in the Stradivarius to modern day tonewood. What did they find?A greater percentage of wood in the Stradivarius had decomposed. As a result of the degradation, the absorbed water content was lower. There were also different minerals found in the Stradivarius. These minerals came from chemical treatments practiced by Cremonese instrument makers.These differences affect the vibrations in the violin. With reduced water content, sound resonates better. This allows the instrument to achieve its distinctive brilliance.Maybe we could bring Bach the Stradivari sound? “Wooden” that be nice? No strings attached.
