Do you understand why G Major is the dominant of C Major? Or why C Major is the dominant of F Major?

My key selections are dictated by open string notes. I find it very useful to choose a key that has all, or most of the open string notes in that key. It gives great sound dynamics, and ease of play, even when moving down to higher pitches. Key selection may also be dictated by the vocal range of the singer, but do I understand why one key is dominant over another, no. I am not even sure what you mean by dominant.
These principles you are trying to explain will be best grasped by those of use that are curious if you can find a way to show them in relation to the fretboard, and appeal to a wide range of skill levels. For that you effort im sure would be greatly appreciated. :cool:
