An artist creates a poster celebrating a famous musician’s impending visit to his community. In his poster design, he places a large bust-length portrait of the musician surrounded by smaller images of fans and music venues. Which principle is the artist using to create emphasis in this poster?

the answer is counterpoint.

counterpoint definition: "the art or technique of playing a melody or melodies in conjunction with another, according to fixed rules."

counterpoint is present in a lot of baroque music- such as bach (notably his wtc prelude and fugues) and scarlatti, but can also be found in music by mozart, beethoven. it can even be found in music as modern as john williams!
