What is a major scale?

Today I’ll talk about how the major scale is derived. To understand this chapter, you must understand what half steps and whole steps are. You must also know what sharp notes and flat notes are.
The major scale is derived from a W W H W W W W H formula.
W is equal to whole step.
H is equal to half step.

The 12 keys of music are the following:

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

We'll derive the C scale now from the above notes using the following formula:
W W H W W W W H

A whole step from C note will be D. A Whole step from D is E. A half step from E is F. A whole step from F is G. A whole step from G is A. a whole step from A is B.
A half step from B is C. when you reach C again, it's called as octave.
So the C major scale is the following:
C D E F G A B C

By checking the scale, you'll know by now that this scale doesn't have any sharp or natural notes. This is the only scale which doesn't have any sharp or natural notes.
Scales for other notes can also be derived by following the above formula. If you use the formula W W H W W W W H with D, you'll get the following scale:
D E F# G A B C# D
You can derive the other scales using the same formula. You can try it by yourself. If you have any questions or you can give me feedback by posting a comment.

The following is a simple C major scale which anyone can practice.
E--------------------------------------------------------
B----------------------------------------------------------
G----------------------------2-----------4--------5---------
D------------2-----3-----5-----------------------------------
A--3-----5-----------------------------------------------------
E-------------------------------------------------------------

The major scale is the most important thing in music. This is because; everything is compared to major scale. I’ll be giving some more details about this in future posts.
