Make your poem rhyme, above all.
We kept remembering it after high school:
When writing songs, make the lyrics rhyme, above all.
EXCITING NEWS! You don't have to make true rhymes in songs!
No more struggles to rhyme the next song line with
"The / orange flow- er / bulb _ _ / ....
Pseudo rhymes work fine in songs especially...
the music helps to obscure the lack of perfect rhyme.
So in the above example, your 3/4 time song can continue,
"The / orange flow- er / bulb _ had /
the wrong la- / bel, __ so
in the spring / it bloomed hot
pink." __ __ / __ __ __ :)
obviously a humor song!
