ГАЙДА И ДЖУРА I've established that the каба гайда is larger than the джура гайда and that the two instruments are tuned to different keys: the каба гайда to re (D in the Anglo-American system) and the джура гайда to sol (G in the Anglo-American system). What I have not been able to discover is the meaning of каба and джура. Are the two words translatable?
