I mean all waveforms arease of sine waves right? So the sine wave must be the most common naturally occuring waveform, at least it would seem so...

There are tons; it's just hard to create voltage-controlled versions of most of them over a wide range, which is why the sawtooth and triangle cores we know and love are generally used in musical VCOs.
