That would have to be C. Because most artists would not have a motive to do anything if they were not inspired to do so.
Charlie Parker was the composer who refused to play facing the audience to avoid other musicians figuring out his signature motives and styles.
Popular music can do either of those things, but popular music that stays well known and popular for years and years are those songs and albums that give the people something they have never seen before. Think of some of your favorite artists from the past: Queen, David Bowie, Elton John, etc. They all brought to the table what no one else was able to do and I think those leaps of faith speak for themselves. They are what keep the development of music going and pushing into the future instead of recycling the same old beats until you're beating a dead horse.
Yep, your guess is right! Tenebrism, is the correct answer!
"Tenebrism deals with the extreme contrast of light and dark, along
with chiaroscuro, the two effects were what Caravaggio used to make his
paintings seem so dramatic."
Or maybe I'm wrong xD. Hopefully I helped!
