hey what's up you guys Marty Schwartz
here with Marty music thanks for the
support I'm gonna break down for you I
think the most valuable piece of music
theory if there was only one piece of
music theory that you could know it'll
be this and that's knowing the chords of
the major key so we're gonna zoom in
break it down if you want to get more
into guitar you can sign my newsletter
I'll send you some free courses as well
first comment down there you can see
where you'll go to it but let's get to
it
alright let's work on the chords of the
major key or the major scale it's six
chords that are used all the time in
music but there's the seventh chord as
well we're just gonna you know start
analyzing it and breaking it down like I
was saying in the intro it's it's really
the building blocks for all of music
theory so I think this is a great place
to start I'm gonna pick the key of G so
you hear that doremi scale the first
thing here is we're gonna learn that
doremi on one string and those are going
to be the roots of the chords of that
key so first thing I want to say is that
there's seven notes in the scale before
it starts over again
[Music]
in a major key no matter what key a
major B flat major F sharp major any of
that the third note to the fourth note
is always a half-step and the seventh
note back to the root is always a
half-step everything else is a whole
step so let's start with number one note
number one the root we're talking about
G major right now so I'm gonna play the
third fret on the low E and remember
what I said this is gonna be a good
thing to remember is the three to the
four is a half-step and the seven to the
one is a half step
the rest are whole steps so that means
the one to the two is a whole step it
means the two to the three is a whole
step and remember I said three to the
four so here's one of the half steps
three four whole step to five whole step
to six whole step to seven and then now
you're at that other half step which is
back at the root which is now G again so
we just went through all the notes of
the scale and ended an octave up from G
one two three half step two four five
six seven half step to 1 so that means
if I wanted to play the G Major scale
let's say on one string on the D string
just so we're emphasizing that we're
gonna be starting to you know get this
memorized in little bits mm-hmm there's
a G note there it's the fifth fret so
remember what I said three to four is a
half step in the seven to one so one two
three half step
two four five six seven half-step and
and the exact same thing we're doing
here but we're just using multiple
strings so we don't climb up the exact
same thing but when we do it on one
string now we can just use our basic
Barre chords to put together the chords
now these chords come from these notes
the seven notes are the only notes in
all seven chords so the notes are kind
of like the DNA of the sound of the
melodies the sound of the chords you
know it's seven notes that are put
together in lots of different
combinations to make these chords so one
two three four five six seven one again
so we're talking about that's the G
Major scale so the first note is the
root of the one chord the one chords
always a major chord in a major key so
the one chord of G major is a G major
chord and let's follow those roots we
did the two and the three are both minor
chords so we have G major a minor B
minor three to four is a half step so we
have that note right there which is AC
and it's the four one two three half
step two for the four chords always
major okay and then a whole step to the
five chord and the five chord is always
a major chord but and that's the three
notes but when you add its fourth note
of that chord it's a d7 chord take your
pinkie off you get d7
the five chords the only chord in the
key that's a dominant seven chord so one
two three four five
six is up a whole-step and six is minor
then you have seven and then back to the
one which would be G major now the
seventh tone the chord for that is a
weird chord called a half diminished
chord and it's not really in pop music
so really it's the six chords that are
in pop music let's do it one more time
so the one chord G major whole step to a
minor whole step to B minor half step to
C major whole step to D take the pinkie
off make it a seven chord the six chords
minor then the seven chord no one uses
in in mainstream music
it's used in jazz but right there and
there you have it
[Music]
don't worry about that seventh chord
right now so next what I want to do is
play that same thing but with the a
roots so the one G note is right here on
the tenth fret of the a string and its
major so G major up a whole step to the
two which is minor up a whole step to 3
which is minor and then four is up a
half step which is major so that's C
major and now I'm going to since I'm
running out of runway here I'm gonna do
my five an octave lower right here
and you can do it as a seven chord then
you have six and then like I said the
seventh chord no one really uses oops
sorry and you're back at G again well
what's interesting is if you all the
modes come from this as well so
understanding this and then starting to
see progressions and analyzing how the
keys work it actually unlocks all the
modes but understanding this is going to
be really helpful to you I promise it
opens up a lot of doors may start some
questions but the answers are out there
to find so just start to work on this
here's a couple of little interesting
tidbits you've heard the term one four
five well in the key the one the four
and the five are the only chords that
are major in the key and so for G and I
know this stuff pretty well it would you
know you need to work on it to get it
memorized but the one for the one four
and five of G is indeed I could do this
way to the sixth chord which is E minor
if we took all the chords that we just
played but thought of a minor as the
tonal Center now we're in the key of E
minor doing nothing new except thinking
of that sixth chord as the starting
point okay so that's your mission right
now is to start understanding the chords
of the major key real quick if the one
four and five are major that means the
two and six are minor the seven which we
didn't really work on right now is a
minor seven with a flat five also
sometimes called half diminished and I
just when you're going through the
chords right now when you get to that
seven chord so G major
[Music]
when I get to that final seven chord the
great way to practice that right now is
to play the five chord instead of the
seven chord and then resolve it to the
one so here's what I mean the five chord
is D seven it functions much more
strongly as that final chord so just
something you could do is G major a
minor B minor C major D seven E minor D
seven again because I said do to the
five then the one and it feels really
nice and resolved when you do it that
way you don't have to but what I really
want you to do is be able to see all
right guys I really hope that helped you
also thanks for supporting marty music
that's where i am so i make my new
content as of making this video so I
really appreciate you supporting that
and we'll see you again real soon take
care
