Final answer:
Music typically settles into either a major key, which conveys happiness or optimism, or a minor key, which suggests sadness or danger. The key, harmonies, and melodies all contribute to the audience's emotional response.
Step-by-step explanation:
After the initial opening, the music settles into predominantly one of two types of keys: either a major key or a minor key. The mood of a scene can be greatly affected by the type of key used. For instance, the initial slow and mournful notes of the film's music in a minor key suggest a sense of sadness or danger. The feeling of tension and unease is amplified when there's dissonance, where the sounds don't seem to go together, indicating that the character is in danger. In contrast, should the music switch to a major key with high, bright notes and a bouncy pace, it completely alters the emotional perception of the scene. Instead of danger or sadness, the major key projects a feeling of happiness or optimism. Whether in major or minor keys, the use of harmonies and melodies plays a critical role in evoking emotional responses from the audience.
