Philadelphia physician Arthur Lintgen can recognize classical phonograph records without hearing them. By studying the spacing and patterns of the grooves, the structure of the vinyl, and the number and length of the movements, he can identify most orchestral music composed since Beethoven’s time.

He’s been tested several times, once in the presence of two musicians from major American orchestras. Lintgen studied each record for 15 to 30 seconds, then correctly named Bruckner’s Fourth Symphony, Orff’s Carmina Burana, Rachmaninoff’s The Bells and Second Symphony, and the Saint-Saëns “Organ” Symphony.
