　　Classical music competitions pick performers against each other. Obviously the most important criterion for judges is sound. But that assumption needs a new hearing. Because a player’s passion may be the best predictor of victory.

　　In a new study, nearly 200 novices¹ had to choose the winners of 10 classical music competitions. Some heard a music clip of the top 3 performances, others saw a video with sound, still others watched a silent video. And the participants were more likely to choose the winner if they watched the silent video in all 10 of the competitions.

　　Then professional musicians gave it a try. These judges also only reliably selected the winners from the silent video. Musicians selected the winner more frequently even when all they saw was an outline of the motion of the performers.

　　The researchers say the findings show that the novices and experts make quick judgments² about music performances based on visual cues conveying involvement and passion. The study was published in the Proceedings³ of the National Academy of Sciences.

　　So next time you see a live concert, don’t close your eyes to focus on the music, you might be missing the most important part.

　　Thanks for the minute for Scientific American 60 Second Science, I’m Cynthia Graber.
