im trying to understand this circle thing, it looks like a minor as a chord can be played on any instrument in each octave once & its still the same chord its just in a different octave which means its a higher tone or lower tone depending on the octave you use to play it in. so it looks like i can play the SAME a minor twice on bass & guitar & the SAME aminor 3 times on my small 32 keyed keyboard. please tell me if im wrong or if theres additional information you can give. also the root note of a minor chord is always a in every octave. i think i covered chords with that?? that being said it also looks like according to this circle thing says to me that for some reason i dont understand the sound of a minor in any octave is realative to c major also for reasons i dont understand. i see a natural sign & i dont understand does that mean natural keys can be used too & it will still be c major or a minor?? lots of lacking on the information to the natural note sign thats there. please tell me it thanks. also this circle thing says something about a Bbb what is a Bbb???? i know theres Bb but why are there two bb???? what determines a b or a bb??? is there such a thing as a bbb??? how far does this go and why does it go there & what does all that mean???? im very lost & confused on the example they give in the circle i dont understand it at all please help thanks. also what is it that makes a natural or a melodic or harmony what they are?? i understand nothing about that.
ok now i have just found this page https://www.basicmusictheory.com/minor-scales & this page says that a Bbb is not practical to play or sing im guessing??? im not sure why. please help!

A major scale is made of two tetrachords C D E F + G A B C which have a symmetric tone -semi tone distribution T T S +T T S We are in CMaj .
-If we add a new tetrachord below we must add a flat to keep the TTS distribution
so we have F-G A Bb+CDEF we are in FM

- and add a sharp to the tetrachord above GABC +D E F# G (We are in GM)

So each scale with a common tetrachord have tonic a fifth apart.

If you want to write a mirror ( opposite) scale that respects the key signature the tonic must be a major third above (E in CM) and the scale will be a descending minor scale .
Now if you want to write an ascending minor scale the tonic must be a minor third below ( A in CM) but the TTS distribution is no longer respected and the seventh degree is one tone below the tonic; so you've to add a sharp to have a leading tone (G #) in Am . This leading tone is foreign to the serie (FCGDAE B) so that explaining your misunderstanding of circle.
We could use D instead of A as tonic of the the minor relative scale of CM with a more symmetric TTS distribution than the A one but a C # is needed to form a leading tone
Since A and D cannot form a satisfactory minor image of a major scale the tonal system adopted three forms of the minor scale
The natural minor scale (or descending melodic or aelian scale) A BC D EF G A
The ascending melodic scale ( A Bc D E F# G#)- the F# avoids the undesirable augmented second interval.
The Harmonic minor scale (A BC D E F G#A

A as tonic provide the three forms of minor scale while D would provide only two aspects that why A is the adopted relative scale of CM




Is that clear ?
