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.
