Riff

A riff is like a small part of a song that sounds really cool and catchy. It's like a musical sentence that gets repeated a lot in the song. Think of it like a special dance move that you do over and over again because it looks so cool. Riffs can be played on different instruments like guitars, pianos or even just by singing. They are really important in music because they help make a song sound unique and easy to remember. So, next time you hear a song and you can't stop humming a certain part, it's probably because of the riff!
