Both film and theatre producers are able to bring a story to life using these elements, and their artistic choices can enhance the drama of the story.

Think of one of your favorite movies and consider how different artistic choices were made in the film’s production. Which elements were most effective and why? Could your film be turned into a stage play? Why or why not?

Music and dance

Respond to the following in a minimum of 175 words:

Music and dance are similar because both are able to communicate ideas and emotions without the use of words. In the absence of a vocal part, musicians create sounds that evoke certain emotions. Composers and performers do this through different elements of music like melody, harmony, and rhythm. Dancers can also communicate emotions, ideas, or even a story through their movements, and these movements are often tied to musical elements like rhythm.

Imagine that you are composing a ballet. Pick an emotion that you want to show the audience. Describe how you would use certain elements of music to create the sounds of that emotion. How would you choreograph the dancers to align with your musical ideas?
