Experts can't tell old instruments from new

What gives a violin made by Stradivari or Guarneri del Gesu its remarkable sound? Researchers have examined the wood preservatives, varnish, even the effects of the Little Ice Age on the density of wood for anything that might explain the instruments' almost magical properties.

Claudia Fritz, an expert on the acoustics of violins at the University of Paris, has arrived at a different explanation for the secret. Despite a widespread belief in the old violins' superiority and the millions of dollars it now costs to buy a Stradivarius, the fiddles made by the old masters do not in fact sound better than high-quality modern instruments, according to a blindfolded play-off she and colleagues have conducted. "I don't think there is any secret, except in people's minds," she said.

Many tests have been conducted in which an audience tries, usually unsuccessfully, to guess whether a violinist behind a screen is playing a new instrument or an old master. But Fritz said that to her knowledge, no one had conducted a well-controlled study putting the same question to the real experts: violinists.

Teaming up with the violin-maker Joseph Curtin and others, she corralled violinists attending an international competition in Indianapolis and had them compare three high-quality modern violins with a Guarneri and two Stradivari instruments. The violinists had to wear goggles so they could not identify the violins. In one test they were allowed to play all six violins and asked to choose which they would most like to take home. In another, they were required to compare a pair of violins, without being told that one was a classic and the other a new instrument.

Despite a general belief among violinists that Stradivari and Guarneri violins are tonally superior, the participants in Fritz's test could not reliably distinguish such instruments from modern violins. Only eight of the 21 subjects chose an old violin as the one they'd like to take home. In the old-to-new comparison, a Stradivarius came in last and a new violin as the most preferred.

"These results present a striking challenge to conventional wisdom," Fritz and her colleagues reported online in The Proceedings of the National Academy of Sciences last month. Fritz's conclusions, naturally enough, are music to the ears of modern violin-makers. Violinists view them with less rapture.

Old myths

The study is "highly credible," said Sam Zygmuntowicz, a luthier (as violin makers are called) who has made instruments for Isaac Stern, Yo-Yo Ma and the Emerson String Quartet. It "puts cold water on some old myths and should certainly be good news to young musicians who yearn for violins that they will never afford."

Does this mean there is no lost secret of the legendary Cremona violin-makers (like Stradivari)? "It's impossible for us to say," he replied.

A less respectful view of Fritz's study is offered by the violinist Earl Carlyss, a long-time member of the Juilliard String Quartet. "It's a totally inappropriate way of finding out the quality of these instruments," he said. The auditions, he noted, took place in a hotel room, but violinists always need to assess how an instrument will project in a concert hall. He likened the test to trying to compare a Ford and a Ferrari in a Walmart parking lot.

Fritz acknowledged that her study used few violins. But it is quite difficult, she noted, to get owners to lend out their million-dollar instruments to be played by blindfolded strangers.
