A horn is like a special kind of loudspeaker that makes a big noise to get attention. Think of it like a trumpet that you blow into to make a loud sound. When you press a button or squeeze it, it makes a noise that says, ‘Hey, look here!’ It’s very useful for people driving cars to let others know they are coming or to say ‘hello’ to someone far away.
Imagine a unicorn. It has a beautiful, magical horn on its head. This horn is not for making noise but is special and unique. It’s what makes the unicorn different from other horses. Sometimes, people use the word ‘horn’ to talk about things that stick out, like the unicorn’s horn or the horns on a cow.
In music, a horn can be an instrument like a French horn. Musicians blow air into it to create lovely tunes. It’s like when you hum a song with your mouth closed but much louder and prettier. So, horns can be used to make music, to get attention, or to make something look special, like the unicorn’s horn.
