but, I sang high, the part that often children
or, some women would sing, and Zack sang low.
We were singing the same melody.
You always do this in your everyday life.
We were singing in octaves.
Okay?
>> It sounded equivalent.
It didn't sound weird.
It didn't clash.
This is what we mean by the an Octave.
>> So again looking at our stave, let's see what this octaves mean.
Right here's A, and if we count these notes,
A being 1, B 2, C 3, D 4, E 5,
F6, G7, number 8 is when we come back to A.
>> That's not going to be much of a surprise
to us given that we've called it an Octave.
>> The 8.
>> So we've looked at these notes on the stave, but let's just go
back to the keyboard so we can look at where they are on an instrument.
So the A that we've started with was here.
[SOUND] We never got that A.
An octave above [SOUND] up here.
So we had A, B, C, D, E, F, G, and A.
And you'll notice that that's just used every line and space on the stave,
but we've only used the white notes
on a piano and that's going to become important.
We'll talk about that more in a minute.
We can go down to A.
[piano plays]
A, G, F, E, B, C, B, and right down to A.
So again, just to highlight this idea of the octaves.
We've got an A here.
We've got an A here.
We've got an A here.
We've even got an A up here, and this
carries on both ways up and down the piano.
