I'm awful with music theory so I was trying to practice and bought a key book.

I've noticed that the same chords have different diagrams depending on the key that they are in, for instance it shows a C in Cmaj is X32010, however a C in Gmaj is X3555X.

Why is this??

They might be trying to show you easy fingerings for chord progressions.

A C chord is a C chord regardless of the key you're in; the only thing that really changes with the key is the likelihood of using a C chord.

A standard C chord is comprised of the root, the 3rd, and 5th of the chord.


C, E, G

Now - if you fret the notes for the chords on guitar


Same notes, same voicing, different place on the neck.

Probably depends on context, some voicings will work better with different sets of chords.
