Thomas Mitchell told The Telegraph that he and his son, Stuart, also a musician, began studying symbols carved on the walls of Rosslyn Chapel 20 years ago. They were especially interested in 213 carved cubes bearing flowers, diamonds, hexagons and other symbols in the building's Lady Chapel.
"I was obsessed by these symbols," Mitchell said. "I was convinced they meant something."
The Mitchells decided that the symbols are called cymatics or Chladni patterns, which form when powder-covered sheets of metal or glass are vibrated by a musical note. They have now created "The Rosslyn Motet," a piece of music based on the cube patterns.
The 600-year-old chapel near Edinburgh became internationally famous when author Dan Brown used it as a hiding place for the Holy Grail in his novel, "The Da Vinci Code."
Mitchell, who served as a code breaker with the RAF during the Korean War, said that he and his son had a "eureka moment" after years of puzzlement.
We believe this is the Holy Grail of music and, unlike "The Da Vinci Code," it is absolutely factual," he said.
