Just thought it was a strange coincidence, Benoit's 2nd example is ADA, Frisky post's that you can scare the devil with those chords, the D is the 4th to the A, I can't remember if it was the 4th, or the raised 4th that was once called the "diablo en musica" and was supposed to be avoided because it would invoke the devil, just a side note of trivia, btw sometimes I just play the Root&3rd
