I'm working on a short film idea for media. What reason would a wife kill her husband who just returned back from war?

maybe she found another love, or in order to get money he has to have died in the war, and when he didnt she has to do it herself

Explanation:

answer; i believe the correct answer to be (trial films);

i'm not sure i completely understand your question, but i will do my best.

i think the answer you are looking for is sequence. (see below)

a repeated melodic fragment would be best defined as repetition, while repeated chords (different or the same) could be a chord progression. however, you then mentioned the chord and melodic fragment beginning on higher or lower pitches, in that case, the answer could be best defined as a sequence. the definition of a sequence is as follows: "the restatement of a motif or longer melodic (or harmonic) passage at a higher or lower pitch in the same voice."

let me know if this !
