The next and final step, an obvious one hopefully, is simply to erase all superfluous notes leaving just the prominent first / fifth notes to stand alone. Giving us …
The Circle of Fifths
1 Like
The result of all this arranging, matching, pattern spotting, morphing and circling is that we have - quite literally - come full circle. We have reached the point where we have a circle of fifths in front of us. And, crucially, we know its origins, its formation, its essence. We know where it came from.
As a small reward for our efforts so far, here is the coloured circle of fifths again.

In hopes of clarity and good understanding, in hopes of removing any remaining confusion, what follows are further depictions of adjacent major scales with their 1st (root) notes and their 5th notes marked above them.
Compare each of these with the full circle of clusters and the twelve notes of the Circle of Fifths shown alongside.

C major → G major
These two major scales overlap and give us the note G on the Circle of Fifths. G is the fifth note in C major (and the root note of G major, our next scale moving clockwiswe).
G major → D major
These two major scales overlap and give us the note D on the Circle of Fifths. D is the fifth note in G major (and the root note of D major, our next scale moving clockwise).
-
D major → A major
These two major scales overlap and give us the note A on the Circle of Fifths. A is the fifth note in D major (and the root of A major, our next scale moving clockwise).
-
A major → E major
These two major scales overlap and give us the note E on the Circle of Fifths. E is the fifth note in A major (and the root of E major, our next scale moving clockwise).
-
E major → B major
These two major scales overlap and give us the note B on the Circle of Fifths. B is the fifth note in E major (and the root of B major, our next scale moving clockwise).
-
B major → F# major
These two major scales overlap and give us the note F# on the Circle of Fifths. F# is the fifth note in B major (and the root of F# major, our next scale moving clockwise).
-
Note: F# is the enharmonic equivalent of Gb. For the next comparison we convert and use the Gb major scale. This is because we need to recognise that we are moving to the section of the circle containing flat, not sharp, notes.

Gb major → Db major
These two major scales overlap and give us the note Db on the Circle of Fifths. Db is the fifth note in Gb major (and the root of Db major, our next scale moving clockwise).
-
Db major → Ab major
These two major scales overlap and give us the note Ab on the Circle of Fifths. Ab is the fifth note in Db major (and the root of Ab major, our next scale moving clockwise).
-
Ab major → Eb major
These two major scales overlap and give us the note Eb on the Circle of Fifths. Eb is the fifth note in Ab major (and the root of Eb major, our next scale ).
-
Eb major —> Bb major
These two major scales overlap and give us the note Bb on the Circle of Fifths. Bb is the fifth note in Eb major (and the root of Bb major, our next scale moving clockwise).
-
Bb major → F major
These two major scales overlap and give us the note F on the Circle of Fifths. F is the fifth note in Bb major (and the root of F major, our next scale moving clockwise).
-
F major → C major
These two major scales overlap and give us the note C on the Circle of Fifths. C is the fifth note in F major (and the root of C major, our next scale moving clockwise … and also the scale at which we started meaning we have gone full circle).

I may be missing the point, but I think the labels “upper group” and “lower group” should be swapped in the diagram.
Excellent work! Must have taken hours to produce. Thanks.

Thanks for reading and commenting József
Do you mean you think upper and lower need to be swapped within the structure of the quiz answer sheet?
Here is question 11, which is completed on both sides:
The major scale in this question is G major.
The lower group of G major (to the left of the grey cell) is an exact match with the upper group of C major (they make a pair).
The upper group of G major (to the right) is a match with the lower group of D major (another pair).
I hope that answers your query and clarifies the presentation.
Cheers, Richard.

@jacksprat Thanks Chris, I appreciate you reading and commenting, and yes, it took hours and hours (and there is much, much more to come, yet more hours). It’s all a labour of love.

Ah OK, I thought about it the other way around, i.e. the upper part of C major (“upper group”) and the lower part of D major (“lower group”) would yield the G major scale.
Anyway, I’ll spend more time on this as it’s a cool mental exercise.
Will you write about some practical (“real life”) musical applications as well? I know the Co5 comes handy when determining the key signature and it’s common to play a certain riff a perfect fourth higher as a variation, but I can’t recall the same done with a perfect fifth.
And thanks a lot for your efforts!

All good. It did take me a minute to double check if the question was meaning the Lower / Upper group of the “given " scale or the” solution" scale

Seeing the expanded version and then the 12 point circle really brings it home that the

I wouldn’t mind at all if someone came along with a brown envelope full of pound notes! haha

I love the sort of crystal clarity moments in understanding that I hope / think you experienced here.
