Along the way, though, I fell in love with Balkan music. I'm not sure why it was such a draw for me -- I don't have a drop of eastern European blood and certainly hadn't heard it growing up. But something about Bulgarian, Serbian, and Macedonian music was absolutely magnetic, and still is.

Ready for the answer?
It, like all kopanicas (pronounced ko-pa-neetsa; the kopanica is a Balkan dance, so they all have the same time signature) is in 11/16. But you don't have to count up to 11 and then start over from 1; Balkan music is in combinations of 2s and 3s. The 2s are the short, quick dance steps, and the 3s the longer steps; and a kopanica has the form of quick-quick-slow-quick-quick. An easy way to count it out is to use a two-syllable word (I use apple) and a three-syllable word (I use cinnamon) to represent the 2s and 3s respectively.
So a kopanica is apple-apple-cinnamon-apple-apple. Pretty tasty. You might want to go back and listen again, and see if you can count it out.
11/16 isn't the craziest it gets, though. The Macedonian tune and dance "Dvajspetorka" is in 25/16. (Broken up 3-2-2, 3-2-2, 2-2-3-2-2.)
Okay, it's not as hard as it sounds. Really it isn't.
This weird rhythmic stuff comes up because of a study that came out last week in the journal Neuropsychologia that looked at fMRI studies of three groups of people -- musicians trained in the western European classical tradition, musicians trained in the Japanese classical tradition, and non-musicians. In particular they were looking for responses in a part of the left hemisphere that is associated with processing auditory rhythm.
Unsurprisingly, both groups of trained musicians showed greater responsiveness in that part of the brain than non-musicians. What was more interesting, though, was that the western and Japanese musicians didn't respond the same way, especially to asymmetrical beat patterns. Most western classical music has until recently confined itself to symmetrical 2-, 3-, or 4-beat patterns; this is why the exceptions stand out, like the movement "Mars" from Gustav Holst's The Planets, which is in 5/4; and brilliant lunacy like Igor Stravinsky's The Rite of Spring. (The joke amongst musicians is that when Stravinsky was asked what time signature The Rite of Spring was in, he responded, "Yes.")
Classical Japanese music, however, such as the music used in Noh and Kabuki, often use beat-lengthening, called ma (間), which sounds pretty peculiar to a lot of western ears, as if the stretched beats were random. They're not, of course, any more than the 25/16 rhythm of "Dvajspetorka" is; it's just not rhythmically like what most of us are used to. And the musicians trained in classical Japanese music responded to that as a natural, comprehensible rhythm, whereas the musicians trained in western classical music did not.
"We expected that musicians would exhibit strong statistical learning of unfamiliar rhythm sequences compared to non-musicians," said study lead author Tatsuya Daikoku, of the University of Tokyo, in a press release. "This has been observed in previous studies which looked at responses to unfamiliar melodies. So this in itself was not such a surprise. What is really interesting, however, is that we were able to pick out differences in the neural responses between those trained in Japanese or Western classical music."
So our brains really do respond differently to music that we grok. I'd love to see if the same holds true for Balkan musicians as compared to musicians from other cultures; I know that there are talented musician friends of mine who listen to Balkan music with a puzzled frown, and never can quite catch hold of what the rhythm is doing, even once it's explained. But it does show that learning can modulate what's happening all the way down to the neural level.
All of which wants me to get my flute out and play some wacky Bulgarian tunes. Like a neat one called "Nenadova Igra," which is in 9/8. But it's not three 3s; no, that'd be too simple. It's 2-2-2-3. Apple-apple-apple-cinnamon.
Because of course it is.
This week's Skeptophilia book recommendation of the week is about as cutting-edge as you can get, and is as scary as it is fascinating. A Crack in Creation: Gene Editing and the Unthinkable Power to Control Evolution, by Jennifer Doudna and Samuel Sternberg, is a crash course in the new genetic technology called CRISPR-Cas9 -- the gene-editing protocol that Doudna herself discovered. This technique allows increasingly precise cut-and-paste of DNA, offering promise in not just treating, but curing, deadly genetic diseases like cystic fibrosis and Huntington's disease.
But as with most new discoveries, it is not without its ethical impact. The cautious are already warning us about "playing God," manipulating our genes not to eliminate disease, but to enhance intelligence or strength, to change personal appearance -- or personality.
A Crack in Creation is an unflinching look at the new science of gene editing, and tries to tease out the how much of what we're hearing is unwarranted fear-talk, and how much represents a genuine ethical minefield. Doudna and Sternberg give the reader a clear understanding of what CRISPR-Cas9 is likely to be able to do, and what it won't, and maps out a direction for the discussion to take based on actual science -- neither panic and alarmism, nor a Panglossian optimism that everything will sort itself out. It's a wonderful introduction to a topic that is sure to be much in the news over the next few years.
