Sound synthesis articles

As part of some second marking work I was doing for a music technology course, I stumbled across a great set of articles from Sound on Sound, about how sound synthesis works (from the very very basics, onwards)

Having looked through them quickly, I think I'm going to set aside some time to go through these articles properly and make sure my knowledge on this is up to scratch. I guess it's a little off-topic in terms of creativity, but I'm finding that some serious gaps in my knowledge here are causing a bit of a barrier in terms of understanding some of my reading. So this seems like a more successful way to try and plug the gaps rather than ploughing through the massive volume by Curtis Roads, say, on computer music...
