2.which artistic element of theatre (costuming, music, etc.) would be the most challenging

1 - since it's a library, i'd like putting a sculpture from ancient greece, probably from the hellenistic epoch.

2 - i'd also like the statue to be from a famous person from that time, a philosopher of possible.

3 - i'd want the statue to be of a man sitting down on a tree stump with a book on his hands (either writing or reading), to demonstrate the love for reading.

4 - i'd also like to have the statue with a darkish colour and high contrast, as well as a statue that resembles balance and a little movement on his head if he is reading or on his hand if he's writing.

hope it ,

smash that you button and leave a comment below!

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 !
