You classmate Rami is very interested in learning more about the monumental sculptures that were created by indigenous groups in the Pacific Northwest. Typically created from Western red cedar trees, there is evidence these sculptures were created before the 1800s. Raml wants to find
out more about these wooden sculptures. What would you MOST likely tell him to research to get more information?

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 !
