What are the characteristics of background music and sound effects commonly used in videos? How do they contribute to the creation of atmosphere?

If you watch enough of Lao Gao and Xiao Mo's videos, you'll notice that their background music and sound effects are quite formulaic, but that's precisely why people can't stop watching.

The background music is usually low-pitched and a bit suspenseful, like a subtly intensifying rhythm during tense moments, or an ethereal, dreamy sound when they talk about aliens or unsolved mysteries. It doesn't steal the spotlight, but it makes you feel like "this isn't as simple as it seems." This kind of music doesn't draw attention to itself, yet it subtly tugs at your emotions, making you think, "something is definitely going to happen next."

Then there are the sound effects, which are used extensively. For instance, a sudden "ding" or a "whoosh" combined with Lao Gao discussing a bizarre point can give you a jump scare. These sound effects are like a reminder: "Pay attention! This information is important!" Sometimes, when crucial evidence is presented, a heavy "dong" sound is added, like a hammer striking, leaving a deep impression.

Overall, these music and sound effects are like the seasonings in a dish. The story itself is the main ingredient, but without these audio elements, the flavor would be significantly diminished. They give the entire video more rhythm and immersion, making it feel like you're listening to a thrilling and authentic story, and before you know it, you've reached the end.
