Triangle wave

A triangle wave is a shape that looks like a triangle. Imagine you have a line going up and down on a graph, instead of going straight up and down like a heartbeat, it goes up, then across, then down and across again, making a shape like a triangle.

You know how you can make music with your voice or an instrument? When you play a note, it creates a sound wave. A triangle wave is a special kind of sound wave that musicians can use to make different sounds and effects.

Think of it like drawing a triangle with a crayon. When you draw it fast, the triangle looks pointy and sharp. When you draw it slow, the triangle looks smoother and rounder. The sound of a triangle wave changes depending on how fast or slow it goes up and down.

Musicians use triangle waves to create all kinds of interesting sounds, from sparkly chimes to spooky noises. Next time you hear a cool sound in a song or a movie, it might be a triangle wave at work!
