snib writes "An Italian musician and computer technician claims to have uncovered a hidden musical score in Leonardo Da Vinci's "Last Supper." From the article: "[This raises] the possibility that the Renaissance genius might have left behind a somber composition to accompany the scene depicted in the 15th-century wall painting. 'It sounds like a requiem,' Giovanni Maria Pala said. 'It's like a soundtrack that emphasizes the passion of Jesus.'"
Pala published this and other findings about the "Last Supper" painting in his book The Hidden Music, released in Italy Friday." Link to Original Source
