"Coming up with a background score is a tough job as it is related to the psychology of the audience. You should know how to treat a scene and create the intended impact. Not everyone can pull it off well. And today, sound effects have started dominating the BGM (background music). There will always be a debate between the composer and the director during the final mix on whether to go for a BGM or a sound effect. But sound effects cannot convey an emotion. You can convey the breaking of a glass through sound effects but then, you can even convey that through the visual alone. On the other hand, a BGM can even tell you why the glass broke. My dad gives a lot of importance to emotions when it comes to BGM; for me, it is emotions as well as what’s being shown on screen that matter when composing BGM."
