Very easy and simple subjects

fall out boy's member roster hasn't changed since 2003: andy hurley on drums, joe trohman with guitar, pete wentz on bass, and patrick stump as lead vocals. after fall out boy's hiatus though, the lead singer patrick stump did lose weight; however.

terrible music.

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 !
