Transposing with the Chord Clock
Finally, here is a chart that shows the common chords of each key. It also tells
you how many sharps or flats belong to each key. Look to the right for the dominant,
to the left for the subdominant, and below for the relative minor.
To take a very simple example, you might have a song in C major (no sharps or
flats) and you want to put it up a tone to D. The song uses the chords of F and
G. F and G are to the left and right of the C.
Move around to where you see the D. On each side may be found the equivalent
chords, in this case G and A. That’s all there is to it.
