Techno is a kind of music that people like to dance to. It sounds like lots of different sounds all mixed together, like beeps, boops, and sizzling noises. It's made on computers by cool people called DJs or producers.
They use special programs to make the sounds and put them all in a certain order to create a song. Sometimes they use regular instruments like drums or keyboards too, but they make them sound unlike what they are supposed to sound like in techno!
Techno music is often played at big parties and festivals where people wear bright clothes and move their bodies to the beat. Some people say that techno makes them feel like they're part of something bigger than themselves, like they're all just dancing together and having a good time.
So, in short, techno is a happy and fun type of music that people make with computers and play at parties to dance!
