Thanks, the braces certainly clarify things! I wondered about the double ll which one splits in French, but I see you're quite right about Spanish hyphenation. It looks like ros-tro is divided differently form my version too. So, with 2 more tweaks:

Richard, a few editing issues. Chonak made reference to the doubled "l" in the text ("brillar"), which you have corrected. The same applies to the "rr." Both "ll" and "rr" are included in the Spanish alphabet. They are not doublings of single "l" and "r," respectively. As such, according to the rules for hyphenation, "ll" and "rr" stay together at the beginning of a syllable: "bri-llar" and "tie-rra," the latter twice in the text.

The hyphenation of "ros-tro" also needed to be corrected, which you did in your revised setting.

I think that the four or five elisions in the text need to be indicated with an elision mark. Also, I do not think that "que haga" should be elided. "h," although silent, is still a consonant, not a vowel.

I have not addressed musical issues in your setting, such as neums on unstressed, rather than stressed, syllables (e.g., "para"), a neum on the "o'" of "obras," instead of "tus," and a neum on the final syllable of "viviré" (perhaps FA SOL SOL-FA?).

Thanks! I think now we have:

Good catches; something went amiss too with sa(f)can(gh~)do(h).

Modified "sacando", "cantaré", "rostro".
Introduced verse with a "versicle" marker.
