musical phalluses

You could also mention Chichen Itza's "musical phalluses". these are a series of cones that produce musical tones when tapped with a wooden mallet. Supposedly, back in the '20s members of Morley's team had some of them set out in rows like a xylophone and played Xmas carols on them. I've never read of any musicologist studying them to determine their pitches and compare them with Western scales and notation (has anyone else seen something of this sort?) About 20 years ago, the cones were laying stacked in piles behind the old park entrance near the Castillo. Someone put up a sign saying "Do not hit with stones", so of course various tourists who otherwise wouldn't have given the cones a second look banged away at the cones with rocks, breaking many of them

I wonder why no one has tested and measured the notes recently. I would like to see how they compare to music scales from other parts of the world. 

Played in the 1920s? Definitely predates the Stones and other Rock Music. 

They look to be carved as the ends have no evidence of being stalagmites or Stalagtights. 

Not something for a marching band I would think.

They probably gave up on the measuring because the lengths kept changing.
