Basic waveform

By going the addition of frequency of "Overtone",Sine wave will be "transformed" to various waveform!

Or tone of the sound happens to, some of the "transformation", "waveform" has become a basic. That some of the waveform has been referred to as the "basic waveform".

Sine Wave

First"Sine Wave"


Sound made by the "sine wave" is ↓.

Saw Wave 

Next then"Saw Wave"

This "sawtooth" You see that the waveform is has become shaped like a saw.

Square Wave

Next then"Square Wave"

"Square wave" waveform has become square.
Sound of waveform of "square wave" is ↓
