I'm currently writing a vocal piece for a high school SATB chorus in Musescore. Throughout the composition process, I've been using the Musescore playback, **which presents all voice syllables in a Choir Ooh soundfont.** This is my first time writing a(n) SATB peice.

How am I supposed to know whether the layers of lyrics will make sense with the harmony? Or how the piece is influenced by the gender of voices? Are those even pertinent questions? 

What am I *missing* in terms of composition by referring the soundfont?

Is it recommended that I regularly ask the choir to learn and recite their current parts to test playback? If so, how regularly?
