Theory. Chord/Scale vs. Modes. Not sure exactly what you're asking, but for each chord, there is a corresponding mode for the key you're in.
Hopefully some Theory Guru (which I am not) will correct me if I'm wrong First of all, a mode is simply starting a scale on a specific note in the key. In C Major, if you were playing a Mixolydian mode, the scale would be G-A-B-C-D-F-E-F-G (has a flat 7). The Dorian mode would be D-E-F-G-A-B-C-D, etc.... Teoría - Music Theory Web.
