I had an assignment where my music teacher told me to put all my favorite songs onto a playlist. Is this a good selection in your opinion? It's only a few, like 4 since I want to see your opinion before I finish listing the other songs (it's rock and roll, not heavy but hard rock). Chevelle: Self Destructor
Rise Against: Architects
The White Stripes: Seven Nation Army
Three Days Grace: I Hate Everything About You

answer; i believe the correct answer is in new york,in subway stations,public murals and night clubs;

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 !
