It means "drum"

Here are some XM channels I've been diving into lately.

XM 72 Beyond Jazz - Contemporary Eclectic Jazz
XM 95 Luna - Latin Jazz
XM 102 Ngoma - African music

I noticed 2001 Space Odyssey was on TCM last night, so I watched the first 40 minutes or so and then popped a tape in to catch the rest.

One thing I haven't quite understood about the slabs. Is the one that appeared to the monkey men the same one that was buried on the moon? If so, the aliens must not be very bright if they couldn't figure out the monkey men were not exactly technologically advanced. The aliens put the thing on the moon so they'd know when humans were ready for the next step, but if they knew it would take a tremendous leap to get to that point where humans could discover it, then why didn't the aliens know that monkey men braining each other with bones weren't ready for contact yet?

If it is a different slab, isn't there a slab still on Earth somewhere? Perhaps it's being used as a table in some remote village.

I've started in on Myst IV: Revelation. I've made it through the initial Tomahna stages, and I'm almost through Haven. I've only had to consult the walkthrough for a couple things, and in those instances I knew what the puzzle was looking for, and had all the pieces, but couldn't quite get things in the right order and didn't want to spend a lot of time figuring it out when I had already got the key elements.
