Sure, it's pretty clearly supposed to mean a crescendo, even if you don't read the English on the Skybox card. ("...and others roar in a great crescendo.") I meant the grammatical structure of the phrase beyHom bey bey'a' itself. I don't think there's any other examples of a series of nouns being used on their own to express that a thing is changing over time. It doesn't really make sense as an appositional phrase or a noun-noun construction. It looks like it could be an "and" phrase, but there's no je. The proverb bogh tlhInganpu', SuvwI'pu' moj, Hegh uses sentences in a series to convey events over time without a conjunction, but those are complete thoughts, and there's no reason they couldn't be written as distinct sentences. Is the expression beyHom bey bey'a' generalizable?
