Voiceover music, also known as background music or underscore, is a type of music that is used in film and video production to enhance the overall impact of the voiceover. It is played during the recording of the voiceover, and its purpose is to help convey the intended message of the production and to create an emotional response in the audience. The music is chosen to complement the mood or tone of the voiceover and to help set the scene or create a specific atmosphere. For example, if the voiceover is in a dramatic scene, the music might be chosen to create tension and suspense. Similarly, if the voiceover is in a happy or uplifting scene, the music might be chosen to create a sense of joy and positivity. Voiceover music can also be used to provide context for the voiceover, such as when it is used to indicate the location or time period of the scene. Overall, voiceover music plays an important role in helping to create an immersive and engaging experience for the audience.
