Clock Visualization

Circle Scales Grid Enharmonic 5ths Note Changes Common Notes b/t Keys Harmony b/t Keys

So assuming C is "12 o'Clock", our circle of fifths looks like this:

F C G
B♭ D
E♭ A
A♭ E
D♭ G♭ B

Since the standard Western chromatic scale is composed of 12 notes, they match up to the 12 hours of an analog clock. Closely-related keys are adjacent, both clockwise and counter-clockwise, while the distantly-related keys are opposite (6 fifths (or "hours") apart).

Moving only clockwise and using strict naming for each P5, we require to start using sharps once we hit 6 o'clock. Notice that the sharp keys are enharmonic to the flat keys above. Here's the same visualization using sharp keys instead of flats:

E♯ C G
A♯ D
D♯ A
G♯ E
C♯ F♯ B

If we kept going, B♯ would be the next P5 we reach at 12 o'clock, enharmonic to C. We could keep going around and start using double, then triple sharps, and so on. On the other hand, if we move strict P4's going clockwise, we get the following:

F C A♭♭
B♭ E♭♭
E♭ B♭♭
A♭ F♭
D♭ G♭ C♭

If we kept going, 12 o'clock would be D♭♭, and again, we'd be venturing into double and triple flats and beyond.

And if 12 o'clock is the root, the interval between root and each note is as follows:

P4 U P5
m7 M2
m3 M6
m6 M3
m2 tt M7

Notice the 2 intervals of equal distance from the root are inversions of each other (P4 - P5, m7 - M2, m3 - M6, m6 - M3, m2 - M7).
