ELI5: Explain Like I'm 5

Harmonic (mathematics)

Alright kiddo, let me tell you about harmonics!

You know what a sound is, right? It's something you hear with your ears, like when someone talks to you or when you play with your toy guitar. Well, did you know that every sound is made up of different sounds put together in a special way? These different sounds are called "harmonics".

Think of it like building a tower with blocks. The blocks are your harmonics, and you stack them on top of each other to make a tower. Each block is a different size and shape, and when you put them together in just the right way, you get a cool tower that looks and sounds great!

Now, let's talk about how harmonics work with music. When you play a note on a guitar or a piano, for example, it's not just one sound that comes out. In fact, it's a whole bunch of different sounds that are all related to each other. These different sounds are all harmonics!

The first harmonic is the "fundamental" sound, which is the main note you hear. But then there are other harmonics that come through too, like a higher-pitched version of the same note or even different notes that match up with the first note in a special way.

So, why do we care about harmonics? Well, they help make music sound richer and more interesting. They also help us understand how different instruments sound the way they do. And if you're really good at math, you can even use math to figure out what harmonics are present in a particular sound!

I hope that helps you understand what harmonics are, kiddo. Remember: harmonics are like building blocks that make up sounds, and they help make music sound cool and interesting!
