Okay, The more I start to kind of figure out about music the more confused I get. I understand how to find the root of a scale and how to find a scale pattern in the key of...whatever. (I think) After reading Pacman's scale practice advice, I got to thinking how and when does the scale stop being in the key of C? I read what is said about playing an octave and 1/2 in the "box" but does the scale stop being a c-maj scale when you move out of the box? How do you tell how to play when someone says it is in the key of G for example? I just don't quite connect the relationships here.
