The Rosslyn Motet: Ciphered Music in the Rosslyn Chapel

The Collegiate Church of St Matthew, aka the Rosslyn Chapel, was founded as a Roman Catholic collegiate church at the village of Roslin (Scotland) in the mid-15th century. The Chapel is a major feature in Dan Brown's "The Da Vinci Code", and is rumored to house the holy grail.

The interior of the Chapel is filled with intricate carvings. Among those are a sequence of 213 cubes protruding from pillars and arches with a selection of patterns on them. The nature and meaning of these patterns have long been a mystery, until recently. Thomas and Stuart Mitchell have interpreted the patterns as a musical score, where the patterns is viewed as those seen in the study in cymatics.

Thomas and Stuart Mitchell placed powder upon a flat surface, vibrating at different frequencies, to recreate the patterns found on the so called "musical boxes". These Chladni Patterns were then matched to their corresponding musical frequencies, to write a musical tune that the team calls the "Rosslyn Motet".

Notice the pitch of the oscillator, hum the pitch to yourself and keep humming until u hear the first note of the choir. You will notice that they are one and the same.
