Many researchers have sought explanations for the purported tonal superiority of Old Italian violins by investigating varnish and wood properties, plate tuning systems, and the spectral balance of the radiated sound. Nevertheless, the fundamental premise of tonal superiority has been investigated scientifically only once very recently, and results showed a general preference for new violins and that players were unable to reliably distinguish new violins from old. The study was, however, relatively small in terms of the number of violins tested (six), the time allotted to each player (an hour), and the size of the test space (a hotel room). In this study, 10 renowned soloists each blind-tested six Old Italian violins (including five by Stradivari) and six new during two 75-min sessions-the first in a rehearsal room, the second in a 300-seat concert hall. When asked to choose a violin to replace their own for a hypothetical concert tour, 6 of the 10 soloists chose a new instrument. A single new violin was easily the most-preferred of the 12. On average, soloists rated their favorite new violins more highly than their favorite old for playability, articulation, and projection, and at least equal to old in terms of timbre. Soloists failed to distinguish new from old at better than chance levels. These results confirm and extend those of the earlier study and present a striking challenge to near-canonical beliefs about Old Italian violins.subjective evaluation | music | perception T he violins of Stradivari, Guarneri "del Gesu," and other Italian makers of the 17th and 18th centuries are widely believed to possess playing qualities that are both immediately discernable to experienced players and not found in new instruments. Over the past two centuries, numerous playing and listening tests have challenged this belief by pitting new violins against old (1-3). Although results often favored new instruments, the tests typically lacked sufficient rigor for the results to stand as scientific evidence.It is only recently that well-controlled studies of player preference have appeared in the literature (4-6). In a 2010 doubleblind test held in a hotel room at the International Violin Competition of Indianapolis (4), 21 experienced violinists compared three new violins with two by Stradivari and one by Guarneri del Gesu. Results showed that the most-preferred violin was new, the least-preferred was by Stradivari, and players seemed unable to tell whether their most-preferred instrument was new or old. However, the small number of violins and brief evaluation periods (less than an hour for each player) left many questions unanswered, the most obvious being whether results would hold with a larger set of test violins, a different group of players, longer evaluation periods, and more true-to-life test conditions.Although the Indianapolis study focused on player preferences, violin quality can be judged from several other relevant points of view-including those of listeners, colleagues in an ensemble, recording engineers, and o...
