Each fret represents a half-step increase
in pitch. Then if you place the capo on the first fret and play the
chord of G you will hear the A-flat chord.
The following list will show the actual
chords when you play the chords in the key of G.
First Fret = Key of A-flat
Second Fret = Key of A
Third Fret = Key of B-flat
Fourth Fret = Key of B
Fifth Fret = Key of C
Usually this is where you stop using the
fret; but here are more.
Sixth Fret = Key of D-flat
Seventh Fret = Key of D
Eighth Fret = Key of E-flat
Ninth Fret = Key of E
Tenth Fret = Key of F
