Well, I actually know quite a bit of music theory. I sort of know what modes, are but sort of not. SO I'm gonna ask my guitar teacher. But yeah, I figured out the reason after I posted it. Instead of giving him what the chorus really sounded like, I just gave him the chords, and told him to strum each really quickly xD(which I forgot wouldn't work). Plus I didn't have the last part. But instead of just doing the chorus(the real chorus progression), my teacher showed me something I got interested in that sounds quite good. He had me play the melody with tremolo picking and he played the G chord with the 5 as the bass and then went to the 4. Which not only sounds very good, but is also very easy to switch to.
