HURRY I HAVE 40 SECONDS TO ANSWER THIS!!

bass?

Explanation:

i think its bass, sorry thats its been more than 40 seconds :(

you make more money, you can get a better job, you have a better education, you are wanted more by most employers.

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 !
