Should i start making YT videos again???

Yes please gonna like, subscribe it if wanted

btw whats yr channels name?

well, what were they about? if u want to then sure! even though i cant get on you.tube rn i would probably support u anyway!

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 !

trying using google im so sorry
