What is the purpose of the art form? Is it a functional object as well as a work of art? What are the materials used?
How does the chosen artwork utilize the elements of art: line, shape, form, value, color, texture, and space?
How does the chosen artwork utilize the principles of design: emphasis, repetition/pattern, movement/rhythm, contrast/variety, balance, proportion, and unity?
What is the cultural context of the work? Is it a religious piece? Was it made to protest or support something? Is it purely decorative?

Explanation:

Functional art represents fine art which serves utilitarian purposes. It includes all the things we may see in our daily life from lightning and furniture to small decorative elements. We can say that functional art has regards more to usefulness rather than beauty or ornamentation.

Water color paint, show card paint, brushes, crayons, pencils, clay, lettering pens, weaving materials, papier mache, chalk, paper of different sizes, soap or wood, beaver board, linoleum, dyes, wool for weaving or stitchery, sheet cork.

Repetition is simply repeating a single element many times in a design. For example, you could draw a line horizontally and then draw several others next to it. Repetition can be useful in web and app design. For example, you'd expect the logo of a business to be repeated on every page and in the same place.

where is the excerpt?

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 !
