Hi i,m about to embark on learning to play the guitar and i can read music,know scales,circle of 5ths/4ths etc.So i thought apart from the practice i should pick up the guitar theory fairly easy,now remember this really is day one and my guitar hasn,t even arrived from ebay yet and i,m not familiar with callouses in any way shape or form in playing a piano and hadn,t reckoned on that when i got keen on this guitar learning course and that,s the first thing everyone is talking about and the no pain no gain macho stance anyhow here the real nitty gritty that baffles me a complete guitar novice on looking at the guitar fretboard i don,t see the usual CDEFGAB what happened to C ok i know there are only 6 stings so somethings gotta give and it looks like it,s C but how then do i relate the key of C to the fretboard as in my head i,m used to having the Key of C and it,s concrete presence.So will some one please reveal to me how do i get a C.......so i can move on and unravel this fretboard code.
