"The Rosetta Disk, is a three-inch puck of microscopically etched nickel and titanium documenting 1,500 human languages. Inspired by the ancient Egyptian Rosetta stone, the Rosetta disk is intended to serve as a long-term cultural backup, a durable archive of ever-evolving (and rapidly disappearing) linguistic forms. A copy of the disk is currently on board NASA's Rosetta Spacecraft." Learn more about Rosetta - a spacecraft en route to Comet 67P/Churyumov-Gerasimenko, where it will make the most detailed study of a comet ever attempted (see http://www.exploratorium.edu/tv/index.php).
This is a landmark in human language documentation. Can we go further and document human musicking in this way?
