Set a melody to words -
I don’t suppose there’s any correct or incorrect choice of voice, although a “machismo”
text might suggest an adult male voice, while a more “feminine” text, a female voice.
But given their can be no accusations of sexist bias and the texts are generally
gender neutral, I would pick a voice to suit a clef you are most comfortable working
in:-
i.e. “pick” a soprano voice if you want to work in the treble clef, a baritone voice for the bass clef.
I write “pick” in quotes because you never explicitly state the voice you are writing
for (unless you include it as a “performance direction”, which I would recommend)
-
So whatever voice you “pick”, you must work within its pitch range -
