Music has a good relationship with photography.

Music flowed from the camera. The sounds in all movies constitute a unified sound spectrum. The echo of music in different narrative spaces is also different. Music is an inherent emotional movement in movies and an important factor in picture creation. Sound strengthens the role of space scheduling and further expands the film space. Music provides a prominent background for every emotion and every action. The tension between sound and visual frame makes the sound finally break through the frame. Therefore, a movie space larger than the visual frame space is established. Film composers should consider film music from the composition of the whole vocal cords, which requires that human voice, natural sound and music be considered as an organic whole. Uncontrolled sound often destroys visual expression, especially in saturation and rhythm. The visual time-space rhythm of movies has become the time-space rhythm of audio-visual combination, and its forming factors are not only richer, but also more complex and delicate. When the music in the non-narrative space is combined with the natural sound in the virtual and real space, it forms a unique thickness, and when it is combined with the light on the screen, it forms a very complicated impact.
