(Music Theory for Beginners)
(Music Playing)
Hi, My name is Sam Dhanasekaran and welcome to this Music Theory Video Series. In this video
let us take a close look at these Octaves. How do I refer each
piano key. Suppose if I want to play this piano key, how do I tell someone that I am going to play this piano key?
Can I say that I am going to press this
first
piano key of
third octave?
Probably Yes. But that would be confusing. So what can I do?
This is where the notes come into picture.
Music theory names each piano key with a name.
The names consist of
just an alphabet. You will see some numbers and symbols after the alphabets. I will explain about them later.
 
The first piano key
in an Octave is called
as C. Let's take this Octave.
Ok. This one.
So the first key is, first piano key is C. The next one is D. Then
E
F
and G.
Ok. After that it goes to A and ends with B.
If you look at the next Octave which is
this one you would notice that this naming standard repeats there too.
From C
to
G
and then to A and B.
Now things get a little easier.
I can refer
this piano key
as note C2.
Why? Because it is the note C which belongs to
Octave 2.
Ok. So in this
video I am showing Octave 2.
There is Octave 1 which is on the left side of this video.
Ok?
Then
this one.
That's A 4
as this is the note A in Octave 4.
Also from now on I am not going to refer these piano keys
as piano keys. Instead I am going to refer them as Notes. Why?
Because in Music Theory the word KEY represents something else which we will cover later and I do not want
to confuse Piano Key and that KEY. OK?
Thank you for watching.
