Which statement about the early american samplers are true? choose all that are correct a. they were sewn by schoolboys who learned from their art teacher. b. they often showed the alphabets, numbers, poem, sayings, names, and birth dates. c. they had borders with pictures of houses, birds, flowers, and trees. d. they were made with cotton thread on wool or leather.

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 !
