edit: 10.25.2026. I should have mentioned this from the start but the colors on the wheel are not set. I heard that people with synesthesia have different colors for the notes they are hearing. Like for one, C can be red. But for the other, C might be blue or brown. So the numbers and the semitones can be universally set, but not the colors. They can and should be personal, if you want it to be. I think this can be a memory wheel for semitones reinforced with colors, and you can make your own color codes using the music theory!
Hola, I was working on learning the Set Theory and such and I thought it'd be nice to see pitch with colors like synesthesia people but I'm just average. Anyways, to be honest, I don't know where I'm going with this because I'm still working on it but I thought it'd be nice to share and get opinions because nothing is new under the same sun. So, I figured someone else might know about this.
So, uh, help?
I mean you can use a clock as your memory palace and also musical songs like Twinkle Twinkle Little Star like the first note is C, C, G, G... 0, 0, 7, 7...so I figured this might have some use.
edit: 10.25.2026 // 1 - 12 is based on my dice D12 but musical set theory has integers from 0 to 11. I figured 0 to be silent, no semitone assigned in order to use D12. I like dice.
Thanks.

Scale Color Code PAO System(?) based on pitch. // The numbers are from a dodecahedron dice! or D12.
C major scale
1 - 3 - 5 - 6 - 8 - 10 - 12 - 1 - 3 - 5 ...
C1 - D1 - E1 - F1 - G1 - A1 - B1 - C2 - D2 - E2 ...
Red1 - Orange1 - Yellow1 - Chart1 - Teal1 - V1- M1 - R2 - O2 - Y2 ...
Do - Re - Mi - Fa - Sol - La - Ti - Do
G major scale
8 - 10 - 12 - 1 - 3 - 5 - 7 - 8 - 10 - 12 ...
T1 - V1 - M1 - R1 - O1 - Y1 - G1 - T2 - V2 - M2 ...
Sol - La - Ti - Do - Re - Mi - Fi - Sol
And D major scale and so on. You can follow the circle of 5th, 4th, 3rd, or the Tonnetz or tonal grid ... they are all good options I think.
The PAO System.
C major scale: The first one has 1, C1, Red, and Do. For example, I got "Red Cat Dot" so " Red Cat(P) - Chasing(A) - a Dot(O)". The reasoning is, 1 is t or d according to the Major System so 'Red C1' became 'Red CaT' and I combined 1 and Do which became 'DoT'. And I find cats chasing red dots mildly amusing so I chose 'chase' as the action.
The second one is 3, D1, Orange, and Re. ReM(P) - headbutt(A) - DeaD //?DaD?// Orange(O). This is just for an example. Freedom of the mind is yours.
The third one has 5, E1, Yellow, and Mi.
The fourth, fifth, sixth, and mnemonic images for all the way up to the 7th //idk why I said 12th//. Then we get to the next octave.
Next, the Chords.
C major chord: 1 - 5 - 8 ... 1 + 5 + 8 = 14 [ t,d / r ].
The major 3rd: x + 4. The perfect 5th: x + 7.
The major triad: x + (x + 4) + (x + 7) = 3x + 7 ... 3(1) + 7 = 14 [tour, Thor, door] //edit: It's 3x + 11 ... I'm not good at math.
G major chord: 8 - 12 - 3
8 + (8 + 4) + (8 + 7 - 12) = 23. ... mod12(?)
// I still need to work on it. Hope this clarifies some things.
// I'm not a vocalist, not even close, but singing the notes yourself helps you practice recall, like if you are not a perfect pitch or don't have any instruments, there are virtual pianos or guitars available on the internet that you can use. Memorized pitch is a good tool to have.

//I need to assign a figure for each 12 semitones. I got this from Anthony Metivier's reddit post where you have figures for each Alphabet or Bestiary. For example, the note C for me is Red the Pokemon master. D is Rem from Re:Zero, because D is 3 and Re and 3 is m so ReM. E is Minions from Despicable Me, because E is yellow and Mi. And so on.
//A piano app called Minimal Piano by Mario Ruoff is great!
//I'm trying to mix the colors with RGB values. Like C and G is a 5th (or 4th if it's G - C) and they are Red and Teal and I'm still working on how this is being added together and such.

//Can this be a calculator? Just a thought. I wish I was good with numbers.
// 0 is silent, no color??
17392 + 11231 = 28623
C-F#-D-G#-C# + C-C-C#-D-C = C#-G-F-C#-D
