Chords for Cracking the Code of Major Scales: Whole & Half Steps

In this video, we're going to learn a code that will allow us to play every major scale on the piano.
For computer scientists, codes are made out of zeros and ones.
_ In scales, [C] the code we use [E] is made of [A] whole steps and [G] half steps. _
[F] What are those?
Well, [C] whole steps and half steps are a way to measure the distance between two notes. _
A half step is quite simply the distance between any note and the note immediately next to it.
A whole step is two half [F] steps.
[C] It's important to note that this has nothing to do with white or black keys.
Two keys next to each other are of equal distance regardless of the color.
_ So [N] these are all half steps, [C] _ _ and [E] these are all whole [Ab] steps. _ _ _ _
[Am] _ _ Let's take another look [C] at our C major scale now, but with this [Gm] new perspective of whole steps and half steps.
[Am] You might notice [C] that some of the white keys are separated by [F] whole steps, and [C] some of them by half steps.
If [Am] we take an even [C] closer look, we [G] start to see [C] a pattern emerge.
[F] _ _ [C]
Whole, whole, half.
[A] Whole, [C] whole, [G] whole, half.
_ [C] We've just cracked the code of the major scale.
[G] It even looks kind of like Morse code.
_ Let's [D] try it with a G major scale. _
Notice that we have to [G] add a black key, an F sharp, right at the end to make the pattern work.
_ [D] _
Or a D major scale.
_ This time we have to add two black keys to make it work. _ _
Or even something a little [Bb] bit crazier like a B flat major scale. _ _ _ _ _ _
Are you starting to see the code now? _
Try to see if you can figure out every major scale on the keyboard using this pattern.
If in doubt, trust your [Bb] ears.
_ Later we'll use these same [G] whole and half steps in different [Bb] patterns to learn countless other scales.
