Here is another Rhyming Distich, and here are some more posts with Rhyming Distichs. I found this poem in the collection Philosophia Patrum edited by Julius Wegeler.
Frustra lingua laborat, si cor non simul orat;
Non clamor, sed amor cantat in aure Dei.
The vocabulary is keyed to the DCC Latin Vocabulary list. There is only one word in this poem that is not on the DCC list:
canto -āre - sing
amor -ōris m.: love
auris -is f.: ear
clāmor -ōris m.: outcry, shout
cor cordis n.: heart; cordī est, it is pleasing to (+ dat.)
deus -ī m.; dea -ae f. god; goddess
frūstrā: in vain
in: in, on (+ abl.); into onto (+ acc)
labōro -āre: toil, work; be in trouble
lingua -ae f.: tongue; language
nōn: not
ōro -āre: pray
sed: but
sī: if
simul: at the same time
