ELI5: Explain Like I'm 5

Semitone

Hey kiddo! Do you love music and singing? Have you ever noticed that some sounds in music are higher or lower than others? Well, those different sounds are called pitches. And music has many different pitches that go together to make a melody or tune.

Now, let me tell you about semitone, which is a tiny, little difference in pitch. Imagine you have a toy car and you want to move it just a tiny bit forward. You can do it by moving it a little bit with your finger, right? A semitone is like that little movement in music.

So, when you move your finger just a little bit forward, the toy car moved a short distance, right? Similarly, when you sing or play music, moving up or down by just a semitone means going up or down by the shortest distance between two notes.

For instance, if you play a note on a piano, and then press the key next to it, you have moved by one semitone. In the same way, if you start singing a song in a high pitch and then gradually bring it down by moving from one key to the next on a piano or guitar, you are changing the pitch by a semitone.

In summary, semitone is a tiny difference between two musical notes. It's like that small movement you make when you want to adjust your toy car by a hair. It's essential in creating different melodies, harmonies, and music styles.
