According to the external form of music in TV programs, it can be roughly divided into "standard version" music and "text" music. "Standard" music is the music that matches the structural landmark units of TV programs, while "text" music refers to the soundtrack interspersed with the content of TV programs. From this perspective, the apparent function of music is its external structural function. The "standard version" music in many TV programs matches the structural logo images of TV programs. Different styles and forms of music are used to divide the areas of different programs, marking the beginning and end of the program, as well as the transition and transition of the program. . The structural function of the "text" music is also very obvious. It is different from and has the function of matching with the "standard version" music.

2. According to the content level of music in TV programs, it can be divided into two categories: subjective music without sound source and objective music with sound source. Silent source subjective music is music arranged during the post-production of TV programs. The music does not originate from the filming object or scene, so it is called "silent source"; it is called "subjective" music because it comes from the narrative subject " Music from a subjective” perspective. Objective music with sound source is the music "emanated" by the narrative object. It can be "on-site object music", that is, songs and music sung by the interview subjects, or it can be on-site improvised soundtrack, that is, filming that is also an object because of its "presence" The former exaggerates and expresses the judgment, tendency and emotion of the subject, while the latter has an objectivity that is truthfully recorded, but is often very infectious and not "cold", because it itself is Reflected as an emotional object.

3. The performance function of music in TV programs

1. Break through the limitations of TV news pictures and expand the performance space. Music is the art of time, conveying information in linear waveforms within a unit of time, while pictures are graphical visions that restore forms of existence outside space to space. Their combination is first based on the extreme nature of the prolongation of time, and then on the intersection of the prolongation of vertical development and the stretch of horizontal development. The resulting complementarity of time and space constitutes Three-dimensional audio-visual space.

2. Music mainly controls speed through beat and rhythm. The application of music in TV programs can adjust the narrative process of the work. The main way is to seize the audience's eagerness to know the inside story and deliberately slow down the process. The narrative rhythm slows down the process of events and creates suspense. Music has the functions of background and transition. The so-called background means that when using music, it must closely follow the content of the TV program, play the role of icing on the cake, and play a certain role in deepening the theme and embodying ideas. Transitions are a means of connecting music in program content, and the use of music transitions is very common in TV programs. Music strengthens the narrative function of TV programs. The use of music in programs allows music as a sound art to intervene in the audio-visual art of television, changing and expanding the expression form of TV programs, and extending the space for TV program creation infinitely. Television music inherits the artistic characteristics of pure music, and combines it with other elements of television to develop the functions of music. At the same time, from the perspective of aesthetic relationship, it brings new audio-visual experience to the audience. Music and TV programs
