Edinburgh-based composer Stuart Mitchell believes he may have found the key to unlocking the secret of Rosslyn's treasure in an unusual form of musical notation. In fact, the idea came from Mitchell’s father, Thomas, who has spent some 20 years grappling with the chapel’s mysteries and now believes he has at last cracked the Rosslyn 'code'. The series of carved cubes high up in the building's Lady Chapel are, he believes, a cryptic form of musical notation, in which the patterns carved on the cubes' faces represent the equivalent of Chladni patterns, with different frequencies producing different shapes, including flowers, rhomboids, diamonds and hexagons – all of which are to be seen on the mysterious cubes.

For Stuart Mitchell this goes "beyond coincidence" and he has been arranging and orchestrating the musical patterns unearthed by his father into his latest composition, The Rosslyn Motet.
