The main forms of expression of music in film and television art are as follows:

1. In-picture music. The so-called in-picture music actually refers to the music included in the plot of the film. The interspersing of in-picture music in the dialogue, along with the subtlety and tension of the music, renders the surrounding atmosphere, enhances the expressiveness of the characters or scenery, can strengthen the emotional expression of the protagonist in the movie, and closely connects the protagonist's emotions with the audience's emotions. Together, the audience's emotions change with the protagonist's emotional changes, whether they are happy or sad, achieving an immersive feeling for the audience.

2. Off-screen music. Off-screen music is relatively fragmented and complex. In thrilling scenes, music can be used to depict the tense heartbeats of the characters in the film, or music can be used to express the characters' inner memories and fantasies. These fragmented and complex off-screen music can be combined with the scenes in the film. The theme music and background music are integrated with each other to enrich and improve the content of the movie, making the movie more vivid and three-dimensional, allowing people to get different musical feelings while enjoying the movie.

3. Audio and video synchronization. The technique of synchronizing sound and picture is relatively simple, the music is completely attached to the picture, and it is often used in cartoons. The most successful application example is the American Disney cartoon "Mickey Mouse" series of cartoons. Because of the full use of the artistic processing of sound and picture synchronization, as soon as the image of Mickey Mouse appears, Mickey Mouse's theme music will appear immediately. The high degree of synchronization between music and images makes "Mickey Mouse Music" popular and widely circulated.

4. Sound and picture counterpoint. Sound-picture counterpoint refers to the strong contrast between music and pictures, making the music more meaningful. For example, in the movie "Schindler's List", the scene of Jewish burials in the concentration camp, dark clouds rolling in the sky, huge firewood piles burning, the shouts of the Nazi officers, corresponding to the panic and fear in the camera, slowly sounded the solemn church-style music Music creates a powerful visual impact.
