What things did neoclassicism celebrate?

Neoclassicism is the name given to the Western coalitions in several many arts such as, visual arts, theater, literature, architecture that creates innovation from vintage art and culture of classical relics.

The simplicity, symmetry and proportion characteristic of Neoclassicism can all also be felt in other art forms, including music, ballet and even clothing. But Neoclassicism was always about more than the arts. It is about our continued cultural fascination with the civilisations of ancient Greece and Rome.

Explanation:

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 !
