The words I have to hyphenate (obviously on different notes) are
Would all these be "is-m"?
"howl" on two notes, maybe "how-l"?
the acronym "J.W.B." on five notes. I'm thinking "J. dou-ble-U. B." but maybe no hyphen after "dou-ble"? It follows several other acronyms that I have rendered as one-syllable letters with periods.
"attire" on three notes, maybe "at-ti-re" but that doesn't look right. I imagine it would be the same as "fire" in two syllables, but I can't recall ever having seen it.
which brings up another point, "the attire is informal—so come just as you are." is the line. I should include the M-dash, but it feels like it should be between syllables like a hyphen, not stuck to "in-for-mal—" with a long space afterward the way it presently is. What is the right thing to do here? I would have no problem inserting the M-dash as an expression if that is indeed the right thing.
