The violins of Stradivari are recognized worldwide as an excellence in craftsmanship, a model for instrument makers, and an unachievable desire for collectors and players. However, despite the myth surrounding these instruments, blindfolded players tendentially prefer to play modern violins. Here, we present a double blind listening experiment aimed at analyzing and comparatively rating the sound timbre of violins. The mythic instruments were listened to among other well regarded and not so well regarded violins. 70 listeners (violin makers of the Cremona area) rated the timbre difference between the simple musical scales played on a test and a reference violin, and the results showed that their preference converged on one particular Stradivari. The acoustical measurements revealed some similarities between the subjective ratings and the physical characteristics of the violins. It is speculated that the myth of Stradivari could have been boosted, among other factors, by the specimens of tonal superior quality, which biased favourably the judgment on his instruments and spread on all of the maker's production. These results contribute to the understanding of the timbre of violins and suggest the characteristics that are in a relationship with the pleasantness of the timbre.
