Which of the following is a technique used to create chinese porcelain vases? a) artists made porcelain from a mixture of pure white clay and feldspar b) artists limited their glaze palette to only one color, to emphasize the brushstrokes c) artists used a piece-mold technique to build vases in sections and joined them d) artists inscribed designs using a stylus, and then covered the vase in slip

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 !
