[PLAYING PIANO]
OK, so the first thing I'd like to do in this segment is review.
We're going to review what an interval is.
OK, so what is an interval?
Right, the distance between two notes.
So if we went from C to E, the 1 to the 3,
that will be a-- right, a major third.
But if I went C to A-- right, a major sixth.
(SINGING) La, la.
Sing that with me.
(SINGING) La, la.
Major sixth.
Next, I'd like to talk about whole steps and half steps.
And as you see on the screen, there is a keyboard
that has whole steps and half steps.
A half step-- if I started on C, to D flat or C sharp,
why don't we call it C sharp, since we're going up.
C to C sharp, that would be a half step.
So you're going one note to the next available note up.
That would be a half step.
If I went from C to D, that would be a whole step.
Because a whole step is two half steps together.
So we have C, C sharp, half step.
C to D would be a whole step.
D to E would be another whole step.
Now E to F would be a half step.
OK?
E to F-- it's kind of tricky because there's no black note in between.
E to F, half step.
E to F sharp would be a whole step.
Now, it's very important that you understand
the difference between whole steps and half steps,
because that is how we're going to construct a major scale.
Now a major scale is constructed like this.
Whole step, whole step, half step, whole step, whole step, whole step,
half step.
One more time.
So it's in C. Whole step, whole step, half step, whole step, whole step,
whole step, half step.
Now I could play that major scale starting at any pitch on the piano
and use that same construction, and I would have a major scale.
If I started on C sharp-- whole step, whole step, half step, whole step,
whole step, whole step, half step.
We do a major scale.
If I started on an E-- whole step, whole step, half step, whole step,
whole step, whole step, half step.
That's how a major scale is constructed.
That's what we get--
[PLAYS MAJOR SCALE]
--C major scale from.
Here's a good way to remember the major scale, is if you sing it,
whole step, whole step, half step, whole step, whole step, whole step,
half step.
[PLAYS PIANO]
Again.
Whole step, whole step, half step, whole step, whole step, whole step,
half step.
[PLAYS PIANO]
Whole step, whole step, half step, whole step, whole step, whole step,
half step.
[PLAYS PIANO]
Whole step, whole step, half step, whole step, whole step, whole step,
half step.
That will help you to remember it.
Songs always help me to remember things.
So hopefully, that helps.
