Tin ear strikes again. I gather I'm meant to be able to work out what each of the feet is from these rhymes? Let's see. I can tell stressed from unstressed, so let's apply that to the first line.

Hm, looks like cataleptic iambic tetrameter to me. So let's try a different track. I can tell open from closed syllables by looking for the presence of a final consonant.

Trochee trips from long to short;
o-o C C C o C

Nope, can't recognize any patterns there. But a "long" syllable in the classical languages is one which is either closed, or has a long vowel. Both tro- and chee- are long the way I say them, so that makes it:-

Trochee trips from long to short;
L-L L L L s L

At which point I confirm I'm not destined for a career in poetry or music, and give up once more.
