Additive
========
* 1822 Joseph Fourier showed that some functions can be written as a sum of sines
* Using harmonics we can build up a variety of timbres
* Theoretically we could use arbitrary many sines to reconstruct almost all sounds

Contra
======
* Gets ressource intensive very fast
* Sound is often too clean, to sterile

Subtractive
===========
* Source with a broad spectrum -> noise
* Filter too thin out spectrum
* Gives much more "natural" sound than additive synthesis
