Peru Update

Ancient Trumpets Played Eerie Notes - Science News: "Acoustic scientists put their lips to ancient conch shells to figure out how humans used these trumpets 3,000 years ago. The well-preserved, ornately decorated shells found at a pre-Inca religious site in Peru offered researchers a rare opportunity to jam on primeval instruments.

The music, powerfully haunting and droning, could have been used in religious ceremonies, the scientists say. The team reported their analysis November 17 at the Second Pan-American/Iberian Meeting on Acoustics in Cancun, Mexico."
