This work of art is attributed to Charles Moore. How did his work incorporate influences from previous art periods?

Charles Moore's Piazza de'Italia is categorized under Post Modernism.

Explanation:

This building is cultural commemoration towards Italian migrants by the American-Italian community. Overshadowed by French and Spanish culture, this building was gathering point for them.

Postmodernism encapsulated many other art movements like Abstract Expressionism, Performance art, video art and other interactive new media art forms.

The two of Postmodernism are 1. Interior Scroll, a performance by Carolee Schneeman and 2. Free Ride, a sculptural installation by Tony Smith.

Postmodernism addresses a freedom from the existing modern art movements. they negate all the evolution and bring to the culture a newer set of forms, imageries and mediums.

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 !
