Bless you, GaryT, for straightening out Terry's problem--which, for the rest of you, was that he was confused because the names of the notes with the capo in different positions didn't seem to make sense--

In classical music, many instruments don't play in the same key, they are called "Transposing instruments", you can think of a guitar with a capo as a transposing instrument, and you can call the fingering the relative chord(so when you play an A fingering with the capo on the 3rd fret, it is a relative A), and you can call they chord that is really sounding a concert chord (so the relative A chord, with the capo on the third fret, would be a concert C chord)
