The role of film and television music is to enhance emotional expression, enhance the audience's viewing experience, create an atmosphere and highlight the importance of the plot.

1. Enhance emotional expression

Film and television music can enhance emotional expression through elements such as tone, rhythm, and timbre. It can interpret the characters' inner world, convey their emotional state, and help the audience better understand and appreciate emotions. For example, tragic music in a sad scene can trigger sadness in the audience, and fast-paced music can increase tension and excitement. This affects the audience's emotional experience and makes film and television works more vivid and infectious.

2. Improve the audience’s movie-watching experience

Film and television music can enhance the audience’s movie-watching experience. By complementing the visuals, music can make the audience more focused and involved in the storyline. Music can guide the audience's emotions, enhance the atmosphere of the scene, and immerse the audience in it. When music and images complement each other, a close connection can be created, allowing the audience to better understand the plot, feel the emotions of the characters, and deepen the memory and resonance of the story.

3. Create an atmosphere

Film and television music can create a specific atmosphere and add color to the storyline. It can create different scenes by selecting different types of music and sound effects, such as suspense, romance, thriller, etc.

Through the sound of music and sound processing, film and television music can directly affect the audience's perception, allowing them to better integrate into the world of the story. By adjusting changes in the speed, pitch, and volume of the music, the audience's experience of the plot atmosphere can be further enhanced.

4. Highlight the importance of the plot

Film and television music can also be used to highlight the importance of the plot. At key moments, the right music can grab the audience's attention and make them pay more attention to what's happening on the screen. Through the succession and transition of music, it can predict the fate of the characters and the development of the story, thus leaving a deep impression on the audience. The repeated use of theme songs or soundtracks in the film can also connect the audience with the plot, enhancing the memory and emotional resonance of the film.
