Understanding the Major Scale

7 days in the week
Mon Tue Wed Thu Fri Sat Sun Mon
1 2 3 4 5 6 7 1
To find the Major Scale in any Key you need to memorize
This simple formula
T 2 2 1 2 2 2 1
Just repeat this formula to yourself a few times
T - two - two - one - two - two - two - one
and soon you will have it memorized
This is very important to know by heart
This formula: T 2 2 1 2 2 2 1
is also known and referred to as Tone Tone Semi-tone etc..
This will be more explained on page 5b, but I am not using this system here as basically
I am using a very easy numeric system
The T = What is called the Tonic or Tonal centre or the Key
For example in the Key of C, C is the Tonic
In the Key of D, D is the Tonic.
