Circle of Fifth/Fourth

This is absolutely one of the most important foundation in music theory. By knowing Circle of fifth (some also call it with circle of fourth), we will understand few things.....


1. Clock wise...

We know that That G Has 1 Sharp(#) on its Scale... D has 2 sharps on its scale.
It is easy to find out actually. The Formula is this

Count 5 steps from C, and we will get G, and the notes are G A B C D E F G. Add # to the last note before G. The notes become G A B C D E F# G. So that's the G Major Scale.

Next Scale would be 5 Steps from G, and we get D Notes. The notes are D E F# G A B C# D.
F# we get from the previous Scale and C# is the formula.

5 steps from D would be A, and the notes are A B C# D E F# G# A.

C D E F G A B C Neutral
G A B C D E F# G 1 Sharp
D E F# G A B C# D 2 Sharp
A B C# D E F# G# A 3 Sharp
E F# G# A B C# D# E 4 Sharp
B C# D# E F# G# A# B 5 Sharp
F# G# A# B C# D# E# F# 6 Sharp
C# D# E# F# G# A# B# C# 7 Sharp

In case you confuse about E# and F. They are the same notes, and 1 notes with more than one name called enharmonic. Why it call E# instead of F? becuase in music theory, we call name according to formula.

2. Counter Clock Wise ( Circle of Fourth)
By looking the circle Counter Clock Wise, we could see another scale, and start with F. Why F, because it is 4 steps after C.

F G A B C D E F, and put b(flat) symbol and the fourth note, in this case would be Bb.

Next note are 4 notes after F, the Bb, and dont forget to alse put b(flat) symbol ont the fourt note Bb C D Eb F G A Bb

The whole would be....

F G A Bb C D E F
Bb C D Eb F G A Bb
Eb F G Ab Bb C D Eb
Ab Bb C Db Eb F G Ab
Db Eb F Gb Ab Bb C Db
Gb Ab Bb Cb Db Eb F Gb


Fyi, Gb actually same with F# scale, but in music theory, it is Wrong if you write Gb Scale by using notes on F# scale, even though they are same in sound.

3. Relative minor
From the circle wi know that efery major scale has it's own minor relative. such G major scale is has E minor as relative minor. etc etc

4. On Staff

We know how to writed 1 sharp Scale untill 7# scale on our Staff.
