Tone 9!

In my Eastern Orthodox days I was a tonsured reader trained in Byzantine chant. I was taught that there were only eight liturgical tones (same goes for the Modes in the Western church). How surprised I was to read this post from The Onion Dome about the discovery of a ninth tone (actually it is tone "square-root-of-29"). This has caused some controversy between the Greeks and Russians, as usual--Not sure how the Antiochians recieved it.
