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 ↓
