Let's move the circle  to another Key.
This time it is the F Key.
This is the F Key, the F note is in the center.
and the 4th chord and the 5th chord likes to be beside the 1st chord.
so the 4th chord of the F key is Bb
The dominant chord of the F key is C. We want to see if this is right.
so we take out our chord chart & here are
the 12 Keys written out for you.
The diatonic chords are in column. The 1st chord, 2nd chord, 3rd chord, the
4th chord, the dominant chord, the 6th
chord & and diminished chord
Right here are the different keys. So we want to look at the F key.
For the F key: the 1st chord is  F
chord & then the 4th chord is Bb
the dominant chord is C. It
should be C7. So it's right.
We come back to the chart and we look at
it. Yes this is perfect.
