HEY
GET A MASK AND PAINT IT THE TRANS FLAG COLORS AND WRITE TRANS RIGHTS ON IT. WEAR IT EVERYWHERE YOU GO.
IF WE DON'T START USING OUR VOICES, THINGS LIKE THIS WILL CONTINUE TO HAPPEN TO PEOPLE WHO ARE DIFFERENT ALL OVER THE WORLD!!!

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 !
