Hey there kiddo! Have you ever listened to music that is really calm and relaxed, like when you're just chilling out and you don't want anything too exciting? Well, that's what we call lo-fi music!
Lo-fi music is a type of music that is intentionally made to sound kind of "low quality" or old-fashioned. It usually has a slow, mellow beat and uses instruments like a piano, guitar, or even a saxophone. The music often has a crackling or static sound, like it's coming from an old radio or record player. This sound is actually called "vinyl noise."
One of the main reasons people like listening to lo-fi music is because it helps them relax and focus. Some people even listen to it while they're studying or working, because it helps them stay calm and concentrate.
So, to sum it up, lo-fi music is just really chill and relaxed music that is intentionally made to sound old-fashioned and a bit "low quality." It's great for calming down and focusing, and it's very popular with lots of people!
