Okay guys, learning guitar and I have a music theory question. How do the particular notes in, say, a G chord combine to make it a G rather than a G minor or E or whatever? The notes in your standard beginner G chord (the only one I know, lol) are G, B, D, G, B, G - why does that make a G?
Other chords confuse me even more. How do C, E, G, C, E make a C? How do E, C, E, A sharp, B, and E make an E chord, and why does it make E minor instead if the A sharp is substituted for G?
I suspect there's a simple answer, but I haven't been able to find one through quick googling.
