Stradivari's Violin Secret? His Talent

A study in the journal Angewandte Chemie that looked at the varnish 1 used in Stradivarius instruments found nothing unusual, leading the researchers to conclude that Stradivari was just a master craftsman 2 who had no secret ingredients unknown to other instrument-makers. Steve Mirsky reports


Almost three centuries after his death, Antonio Stradivari is still a legend for the sound of his instruments, from the rich depths of his cellos 3 [cello sound] to the soaring clarity of his violins [violin sound]. Theories are often been put forth 4 that Stradivari must have used a secret ingredient that made his instruments special, perhaps in the varnish.


Now researchers have performed spectroscopic and microscopic 5 examinations on the wood and varnish of five Stradivarius violins and think they have uncovered Stradivari’s secret. The study appears in the German chemistry journal Angewandte Chemie. The first layer of varnish is an oil comparable to that used by painters of the era. The next layer is a tinted 6 oil and common resin 7 mix. The researchers found no unusual proteins or gums. And they found no mineral-rich layer, which some earlier examiners thought might be there. So Stradivari employed common materials in broad use in his time. Which leads the researchers to conclude that Stradivari’s true secret?: his incredible artistry as an instrument builder.
