Take the major C scale. So the different modes(dorian, etc) use the same notes, but just start and finish on different notes? By doing this it gives a different "feel" to the scale. That's what I think I understand.

Would be curious if there is a good reference out there that helps me figure out all this. I am learning a song, and it uses Dorian mode and it sounds so cool and different, but not sure how one decides to use which mode over a give chord progression.

Any simple rules? I will so my research if some one would be so kind to direct me where to look. Have done searches here and haven't come up with any posts that clarify.
