(Tangentially, I'd always been struck by the resemblance of the musical instrument chuS'ugh to Chusuk, the so-called "Music Planet" in Frank Herbert's Dune. It seems to be little more than a striking coincidence, though; the chuS'ugh appears to have been coined by Howard Weinstein for the TNG novel Power Hungry in '89, probably from chuS + 'ugh, and retrospectively canonised in the TKD Addendum. FWIW, in Power Hungry the chuS'ugh is described as a four-stringed instrument, pear-shaped, about two feet high, and played with a bow while it rests on the knee. Perhaps the cello is the nearest European classical equivalent.)
