Neither one of them even mentioned such a convoluted way of understanding music.
I'm sure the thing was meant to be a joke. I surely didn't take it seriously--made my eyes cross and I didn't even finish reading it.
The year I had to practice sight-singing every single doggoned day kinda marked me, and now I automatically start doing it when I see any string of numbers (including the confirmation number from paying a bill online, oy). Couldn't resist trying it on this one, but honestly, it's really kinda weird and not my cuppa tea at all.
