Constructing Arpeggios: Dominant 7th.
Okay, so that was the major 7th,
now let's get into the dominant 7th.
Just like we altered the scales when
we made, took the major scale and
made it into the different
kinds of minor scales.
We're gonna take the major
7th arpeggio and alter notes
one note at a time to change it from
one form of the chord to another.
The first one were gonna change
it to is the dominant 7th chord.
This is a very, very, very, very, very,
very important chord in music in general.
And in jazz as well and
very, very important and
we will talk a lot about it in the future.
I'd like to just take a minute to,
to to say that
there's an interval in the dominant chord
which is what makes it such a strong and
important chord and it's tritone.
Tritone is an interval.
It's the
remember we were talking about intervals,
how some have two names?
It's the one that's got both the sharp 4,
the augmented 4th,
and diminished 5th name okay?
So its,
that was the 5th, you lower it,
the flatted 5th,
the diminished 5th it's a 4th.
And when you raise it,
it's the augmented 4.
That interval is right in
the middle of a dominant chord.
like on
the interval between the seventh degree
and the third is a tritone,
and it's very, very strong.
Notes sometimes have, a like,
are a little bit like planets.
They have gravity and they pull.
They pull in different directions
especially in relation to each other.
Like the moon has gravity of the,
the Earth is keeping
the moon in a certain orbit.
Well, it's the same thing with notes.
So sounds very cosmic and spiritual.
but it really is true.
So the tritone
is really a pulling chord.
That creates tension that pulls you
in two different directions actually.
What it is if
if the dominant chord is in the key of D,
the dominant chord is, is A, right?
That's the 5 chord.
We'll get into an explanation of that.
It wants really strongly to go to D.
That's called a cadence, right?
It wants to resolve to a cadence.
There's tension, release,
pull and response.
And that inner voicing of
the tritone is what's really
so that's,
that's why the dominant chord
is really really important.
And it kind of pulls the harmony in
different directions in jazz songs.
And kind of,
tends to lead you where you need to go.
So it's an important arpeggio to learn,
and let's get into it.
So, we're gonna go back to
the major seventh arpeggio again,
starting in the same position.
We did the last one in C, did one in A.
Lets, do, let's do this one on G, okay.
So the G scale, first position again is,
getting sick of hearing this but
I like to drill it in,
those six positions are important.
So the arpeggio is this one
that's the major 7th arpeggio.
For the dominant chord we're going
to lower the seventh degree.
Instead of a major 7th,
it's going to be a dominant 7th
A minor 7th, it's lowered one half
step and becomes a dominant chord.
So, it sounds like this
It's a different sound.
Here's the major 7.
Here's the dominant 7.
And of course, it's this chord.
Now let's do it as an arpeggio.
We'll do it nice and
slow so you can play along.
Now we'll move down to the second
finger and do the same thing.
Remember, it's coming off
of this major 7 arpeggio.
There's the major 7.
And we're gonna lower it.
Down to that note in the next octave is
That's where the 7th is
in the major version.
So we're gonna lower it one step there.
Now let's do it nice and slow.
We're gonna get open strings if we
go to the pinky in this position so
we'll slide all the way up here again and
do it up here.
So the major 7th is like this.
But we're gonna lower the 7th and
we'll get
Okay next position,
we switch to the fifth string,
first finger.
I'll just go right to the arpeggio now.
Second finger
on the fifth string
Only up half an octave there.
and then, the pinky.
So those are your dominant 7th
arpeggios in all six positions.
I urge you to really work on this,
both the major 7,
all these 7th chords arpeggios,
they are super important.
They're gonna be very helpful when
we start improvising through chord
progressions, which we're
gonna get to very soon.
I don't want it to be too analytical.
But it is important to have this knowledge
both physically and, and up here.
