I can't see the point of fussing with parentheses. It just makes it
harder to read. Conventionally, one sets the subdivided notes and uses
dashed ties/slurs to join them up. The undivided words are set with a
lyric extension, and the divided words are set as normal except that
it is clearer and neater if you also left align them as if they were
being set under a melisma too.
If the subdivision is unambiguous, ie splitting 2 → 4 4 rather than
2. → 2 4 (which might be 4 2), I often just set the "two words" like
that under the (undivided) note. Doing this with a hymn like "God is
working his purpose out" (Benson—irregular) makes it easy to get a
mistake-free performance.
When the rhythms get completely different for a short passage, you
could try the method that came up here a couple of times recently.
I've never seen anything published this way, but a choir might prefer
it as an alternative to having to turn the page for another fully
written-out verse.
Cheers,
David.
