Well, it's up to you, really. You need to learn a bit how audio 
synthesis works, for instance starting with the following links.

   http://www.acoustics.salford.ac.uk/acoustics_info/sound_synthesis/
   http://en.wikibooks.org/wiki/Sound_Synthesis_Theory
   http://en.wikipedia.org/wiki/Category:Sound_synthesis_types


Then, it's best to learn by programming various wave forms yourself and 
playing around with them. I just finished implementing the necessary 
Haskell backend for playing raw audio data. You can find it here:

   http://hackage.haskell.org/package/tomato-rubato-openal

The  testSine  function demonstrates how it works.
