Background music (BGM for short), also known as accompaniment and soundtrack, usually refers to a kind of music used to adjust the atmosphere in TV dramas, movies, animations, electronic games and websites. When it is inserted into the dialogue, it can enhance the expression of emotions and achieve an immersive audience experience.
