The dominant seventh chord is a really
common chord, it's a great sound.
It's mostly associated
with the five chord.
However like in jazz, particularly
in the blues, you will find that
every chord is a dominant seventh chord or
just a seven chord.
The difference between this chord and
the major seventh chord is only one note
that the seventh scale
degree is going to be flat.
So in the key of D,
the flat seven is C natural.
So in our four note shape for
we have one, one, three, four.
We're just gonna take this top note
from D and we're gonna replace it with
the second finger on the A strings,
so we have the C natural.
[SOUND] That is our default four note,
dominant seven chord.
One, one, three, two.
And in a blues progression,
you'll hear this a lot,
up to G, same hand shape,
back to D and it'll end on A.
So it's a great sound.
Our three note version of this
would be one, four, three.
So we'll put in the seventh
on the G string now.
Together that sounds like this.
And again, it'll work for
the same progression.
But it has a different feeling because
the third is on the top,
instead of the seventh.
You can mix and match these
two default fingers work in every key.
Let me just show you the inversions,
so we've been learning,
let's do the three note version for
Now we've got one, four,
three for root position.
The third is F-sharp and we're actually
gonna put that on second finger.
So that we can hit C natural on
first finger and A on third finger.
First inversion dominant seventh
cord is two, one, three.
It actually sounds like
a diminished chord.
And that's a very clear
harmonic connection between
the diminished sound as
part of the dominant sound.
The second inversion,
it's going to be one, three,
two, from the fifth scale degree,
so the fifth scale degree is A.
[SOUND] And we have one, three, two.
Let me walk up and down these inversions,
so you hear how they sound.
[SOUND] It's kind of like
this growing suspense.
[SOUND] That is your
