Sawtooth wave

A sawtooth wave is like a picture of a mountain, but it's not a real mountain. It's a special kind of sound wave that goes up, up, up in a straight line for a little while, and then suddenly drops really fast, like sliding down a really steep, bumpy hill.

Imagine you're out in the playground and you are riding your bike up a big hill. As you go up, you take deep breaths, and when you reach the top, you suddenly let out all your breath in one big sigh, then start to pedal down as fast as you can. This is like how a sawtooth wave works, going up, and then suddenly down.

People use sawtooth waves to make all sorts of cool sounds in music, like in synthesizers or electric guitars. It's like magic - they can make a computer make sounds like a guitar or any other instrument, just by telling it how to use these sawtooth waves to make different pitches, rhythms, and notes.

So, a sawtooth wave is a special kind of sound wave, like a picture of a mountain, that goes up fast, then drops really fast, and it's used to make cool sounds in music.
