The cromatic scale goes like this, this is basically all the notes you have one after the other = C C# D D# E F F# G G# A A# B C

0= c 1= c# 2= D 3=D# 4= E 5= F 6= F# 7= G 8= G# 9= A 10= A# 11= B 12= C


(# is called sharp)

the numbers before the notes are called intervals, this is what the distance of the notes in relationship to the root is called.
here the root is "c" as an example, but any note can be the root.

0 = Unison 1= flat second 2= second 3= minor 3rd 4= Major 3rd 5= perfect 4th 6= Diminished 5th 7= perfect 5th 8= minor 6th 9= Major 6th 10= minor 7th 11= Major 7th 12= octave

you make the major scale by taking the unison, second, major third, perfect four, perfect fifth, major sixth, major seventh and octave.

and if you have c as the root it will look like= C D E F G A B C
but this formula can be applied to all the other notes and you come up with the other major scales.

G= G A B C D E F# G
D= D E F# G A B C# D

and so on...

after you have a scale you make up chords by using another formula and you get 7 chords from each scale.

in the C major scale you get=

C major, D minor, E minor, F major, G major, A minor and B diminished.


And i think you are correct about the frequencys in the octaves, but i cant tell you the info if you want to know it in Hzs... but you can google it.
