Guitar Tuning Crash Course Video Lecture - Guitar Become a Pro (English)

today we're going to talk a little bit
about tuning and how do we make that
interesting production value
so first of all I want to just really
quickly run through the basic way you
tune your guitar right there's six
strings e a d g ve and I have a snark
clip on tuner right here that Tunes
through vibrations in the guitar right
so if I hit the first lowest string the
low E string right you'll see that it's
perfectly in tune now if it wasn't that
way if it was down a little bit you'll
see that it's even registering a
different note and I can tune up until I
get closer and closer and closer there
it is solid E okay
now the reason you always want to tune
up is because of the gears of the tuner
so the way the gears work when you tune
a tuning peg you're turning one gear up
and it is in turn dragging another gear
up to wind the string tighter or looser
now if you go tighter it'll get caught
like this if you go down if you tune
from like a sharp note down what's
happening is you're pushing down right
here finding the right note and then
over time the other gear is going to
slowly degrade and then it's going to
fall out a tune easier understanding a
little bit more on how tuning works will
give you a different perspective of the
instrument and is this really helpful
long term so I just want to go over a
few quick things now the scale length of
a guitar right is the distance between
the nut and the bridge right here the
saddle where it goes into the guitar
right so when you hit a guitar string it
vibrates until it stops now those
vibrations are measured in things called
Hertz the Hertz is just how long it
takes for one cycle to go through it and
what we know is tuning in the Western
world it depends on these Hertz and
that's how good house are kind of
manufactured so for instance this a
string right here that is vibrating
assuming it's in tune at a hundred and
ten Hertz now something you may have
heard of is a term called a 440 or
concert pitch what that is this is kind
of like something that most of the
musical world has agreed on as a
reference tone by which to tune
everything else was actually like
conspiracy videos on YouTube of why the
musical community went with 440 instead
of like a natural 432 or something like
that but we're just going to assume that
you're operating under normal world
rules and you use a 440 right so a
concert pitch on a guitar would actually
be the third octave
Hey right that's four hundred and forty
years 440 vibrations per second and the
cool thing scientifically is octaves are
always doubled the previous octave so
this a is 110 the next octave a is 220
and the next octave a is 440 and each of
these tones have a couple ways you can
measure you can measure them by Hertz
but something that you may see on tuners
and stuff is a term called sense right
so just like in American currency there
are a hundred cents in a dollar so this
is like a unit of 100 so basically a
tone or a semitone is going to have a
hundred cents that is belonging to that
one note right so this is a C right now
I can go sharp 50 cents or flat 50 cents
where a tuner will still register it as
a C before I get to a C sharp so there's
a range that you can kind of measure
each note now an interesting thing when
you're talking about scale length is
where the 12th fret is positioned now
the way it works out is the 12th fret
will be the exact center point but in
the scale length right so that's going
to be an octave and just how we talked
about with Hertz that's where the Hertz
double right so this a is 110 this is
220 now you can see what I'm really
doing when I'm playing this I'm not just
playing a fret what I'm doing is I'm
pinching the string and only in the
bottom half of the string is vibrating
now right so the way you kind of hold
down any fret or you draw a different
tone from akar is you're pinching and
the sound that you're hearing is the
vibration of a string this thick
vibrating at this length that's why as
you go up the fretboard you're actually
shortening the scale length so not only
this is vibrating shortened strings are
going to vibrate faster depending on
their thickness and stuff to you so
that's kind of how you get variations in
pitch now there are a lot of different
types of tuners that you can use and a
few of them are like like this is a
snark clip on one there's a lot of
different types of clip on ones the
snark is nice because cheap and it's
actually really accurate or if you're
going to find out in a shootout
minute this is going on the vibrations
from the guitar so it's recognizing how
many Hertz are vibrating and telling you
which note it is another thing if you
have like a pickup or an electric guitar
you can get a pedal tuner or rackmount
tuner and these are also known as being
pretty accurate this is a digitech HT -
I got like the Peterson is kind of like
the Cadillac of tuners because it's
super accurate it's also kind of
expensive but whatever I mean these kind
of get by another thing you can do is
get one on your like app on your phone
and that's using the actual microphone
on your phone to do it and the downside
with those is extraneous noises and
stuff can kind of affect it the downside
with the clip-on ones is some of the
lower strings especially if you have
like like a seven string guitar or a
string guitar or if you're in like a
really severe drop tuning the vibrations
from a low low vibrating string might
not be able to be picked up by the
clip-on ones but usually in standard
tuning the clip-on ones are fine I
wanted to find out what was more
accurate the pedal tuner or the clip-on
one so I did a shootout and here are the
results okay so I've got the stark
headstock tuner on the head and I also
have it going through the digitech
hardwired and we're going to do the same
note tuned both ways so I'm just going
to open a string and you can see that on
the snark it's in perfect tune it's
right in the middle not one way or
another there's no sense one way or
another but it's kind of quite a bit
flat on the hardwire so let's tune it to
the hardwire pal
right so now that's in perfect tune
there
but the snark is just a little bit sharp
so let's take both of these and find out
which one is the accurate one with a
software program okay so here are both
tones the one on the left is the start
and the one on the right is the hard
wire what I did is I ran through a
program called Melodyne which is a
really reputable program a lot of people
use for auto tuning but it really gives
you an accurate reference for what the
notes are so as you can see the one on
the left the snark is actually right on
the money
as far as that a string goes and the
hard wire one is actually five cents
sharp so I was kind of surprised I
thought the pedal tuner be better but
the snark actually won this one now one
good way to check the quality of your
instrument and the setup is by checking
the intonation and one good way that you
can do that is checking the tuning of it
open so here's the open B string on my
Taylor
all right so the snark is saying that's
in tune now if I go to the 12th fret and
do the same thing you'll see that's also
in tune so open 12 so this is a pretty
it well intonated guitar now if you just
do a quick check on any of your guitars
you might see a card that needs some
work you might need to set up done or
you can actually Internet yourself
there's a ton of videos online to help
you do that
but that could be a reason why maybe
your guitar doesn't sound good if you're
playing in different parts and maybe in
some instances it'll sound good up here
it'll kind of sound bad the higher up
the neck you play and that's all
intonation so definitely check that out
