Hi, this is Darren with Strumpatterns.com 
and welcome to another video in the
Beginners Music Theory Series. In this
video were going take a look at what is
pitch and what are notes. Of all the
videos in this series, this one is probably
going to have the least amount of
immediate application. However we're
going to be using the terms "pitch" and
"note" throughout the entire series. So, I
think it's a good idea to have an
understanding of what we actually mean by
those things. I also think it'll be
interesting to take a look at what's
happening in the musical sound world
just beneath the surface. At an area
that, often, musicians don't take the time
to really stop and consider. But once we
do, I think you'll find that it has its
kind of own unique beauty to it.
However, if you don't pick up on every
idea thats in this video, I wouldn't
worry too much about it. Because, most of
the concepts in the future aren't going to
really be too related to this. As I said,
it's just kind of an overview of what's
happening and where these ideas of pitch
and note come from. But, once we've
already kinda got that established, we're
not going to need to come back to it
Maybe we can just consider it something
to broaden you as a musician. So just sit back
and relax and enjoy the video! So what is
a pitch? Without getting too technical,
a pitch is a sound that happens at a
specific speed. Now, some sounds are
collections of pitches- like a clap of
thunder has so many pitches happening
out at once that it sounds like noise to
our ears. It becomes indistinguishable. 
But, something that has only a single
frequency with it will sound like a
pitch to our ears- like a single note.
Some sounds will move quicker and those
sound higher to our ears. Some sound moves
slower and they sound lower to our ears.
As the sound gets more simplified,
we can distinguish a specific frequency.
and that sounds like pitch to us. Since
sound can happen in a nearly infinite
number of frequencies, that means that
there are also nearly an infinite number
of pitches as well. However, the human ear
has two important limiting factors and
the first of those is the range of
frequencies that it can hear. So sound
that happens above a certain frequency,
we can't hear. As well as, sounds that
happen
below a certain frequency are also
inaudible to us. The second limiting
factor is our difficulty in
distinguishing between two frequencies
that are close together. So, if you've
ever tried to tune an instrument by ear
and had difficulty with that, that was
because you're running into this
limitation.
So because of these limitations of our
ear, we will select certain frequencies
and will declare them notes. So for
example, at 440 Hertz(hz), there's a note and
then at 220 hz
there's another note. And in between
those two frequencies, we have eleven
other notes that we use. Anything between
440 and 220 that is not one of those
specific frequencies is not considered a
note it simply musically doesn't exist.
so for example 439 hertz is not a note. 438
hertz is not a note. So, different places
in the world have different collections
of notes. They divide up that 440 or
that 220, that range there, they might
divide it up in slightly different ways.
There will be a lot of overlap. There
will be a lot of similarity in the notes
because the mathematics that's actually
happening, and the physics that's
happening there is universal. But there
are certain steps in between some of
these notes that some areas of the world
will use and other areas won't. So for
example, the sitar has some frets
on it that you can't find on the guitar.
similarly with the oud in the Middle
East or the pipa in the Far East. There
are different instruments that have
different notes on it and different
places in the world have different
collections of notes. However, what you're
probably used to hearing on the radio,
for example, is that collection of 11
notes that happened between the 440
hertz and 220 hertz.
So in the video here, you can see the
effect that a single pure frequency has
on water. And noticed that as the
frequency goes up- as the Hertz
increases, that the speed of the waves
also increases, and the shapes that each
wave makes are a little bit smaller. And
of course the opposite is true that as the 
hertz goes down the frequency is getting 
slower and the waves are getting slower 
and each little wave is a little bit larger. 
So, I wanted tothank Moses Hackmon for allowing 
me to use his video. And be sure to check out
his YouTube channel so that you can
watch the original video as well as some
of his other videos that have to do with
sound and water and that's it for this
video but it's not the end of the video
