That's what Tommy and Stuart Mitchell think. They claim the 15th century chapel's ornately carved patterns and cubes contain a musical sequence, concealed "because knowledge of harmonics may have been seen as dangerous, even heretical, by 15th Century church authorities."
This strikes me as unlikely, given that Pythagoras was widely known in the 15th century, but I like a good puzzle as much as the next guy. There's even the possibility that the music will be pretty good. After all, one of my favorite recordings of the last decade posits that there's a hidden obituary for his dead wife contained in J. S. Bach's Chaconne from the Partita No.2 in d for Solo Violin, BWV 1004.
