Thanks, Jack! I'll bookmark that tutorial (and this time I'll print out the pages, for backup)

As for the words and notes, they match up exactly as I composed them in Noteworthy Composer, so syllable-for-syllable, they match. But changing the time signature might make the accents fall out of sync, and that's what the ear and mind really care about.

The last two lines of the second verse refers to the Goddess Frigg's work as a weaver: according to Norse myth, she spun the sun and clouds, and also wove the fleshy bodies for human souls to live in. ...But you'd have to know that myth, I guess, in order to get that. I may have to write another verse to fill in the blanks.

Thanks again for your help, and effort in writing up that new ABC code.
