Is there a name for version of trochaic tetrameter with lines of 8|7|8|7 syllables?

Question

Is there a name for the meter used in Clementine: Drove she ducklings to the water Every morning just at nine Struck her foot against a splinter Fell into the foaming brine or in Schiller's Ode to Joy: Freude, schöner Götterfunken, Tochter aus Elysium, Wir betreten feuertrunken, Himmlische, dein Heiligtum! Most descriptions I've seen of trochaic tetrameter don't mention the possibility of the lost syllable on alternate lines.

Answer 1

I believe the musical note dropping off, carries the last syllable of 8/7/8/7 forward to completion of solid trochaic tetrameter even without a word or uttered syllable to support it--almost like the equivalent of slant rhyme that works if you say it or sing it a certain way. Example: Nine, not pronounced "nine" but "Ni-ine"

I hope that makes sense.
