Chords Progression

I'm still not exactly great at making these chords, but it's making it easier to start writing a loop. I used to just play random notes until i found ones that sounded alright together. I'm not sure if i did the object of the project right, but i wanted to get something posted today, so i just posted it.
It starts out with an "ahhhh" sound that rotates through three different chords. the bass part along with it is playing three notes from one chord. They are C, E and G. (I wouldn't have known that but FL Studio 10 tells me!!!). The two parts seemed to mesh pretty well. After that i took an FPC loop, and switched it up a little bit so it would fit into my song. Eventually a slayer part comes in that has a really laid back loop. I thought the whole sound of the song was unique, but i liked it.
I still need to learn more about the chords, but i hope to continue using them because it makes life a lot easier. I'm not sure how i'm planning to do the next project though. I might stay laid back, but i might make it a little more upbeat, but try to control it so it's not excessive.
