I found something interesting tied to our post back in Februaray titled Sound and the Physical World. Check out the video and you’ll see patterns formed when different pitches
are sent across a metal plate covered with sand. It seems the shapes are tied to carvings found in the 15th century Rosslyn Chapel featured in Dan Brownâ€™s â€œThe Da Vinci Code.â€
The shapes, called Chladni patterns, are named after German physicist Ernest Florenz Friedrich Chladni (b. 1756, d. 1827, pronounced shladnee). After 27 years of study and research into the patterns at the chapel, a 75-year old musician and ex-Royal Air Force code breaker and his composer son Stuart have used Chladni’s patterns to decipher an ancient melody â€œfrozenâ€ in the structure. They were finally able to unlock the melody by matching the patterns to the carvings and are having a world premiere concert in the chapel on May 18, when four singers will be accompanied by eight musicians playing the piece on mediaeval instruments. You can see more details of their findings on their website.
