Okay by now,
you may have been in a jam session
somewhere, and somebody said, oh,
play a G7 there or play a D7 and
you're starting to get confused about all
[COUGH] So let's try and clear up some of
that mystery for you.
So, we're gonna talk about seven chords
Everybody knows a G chord right, we've
shown you that.
The simplest way to, tell you is you
simply, play the F note with your
first finger on the first fret and voila
you've got yourself a G7, that's it.
Here's a little bit of the why of it.
If you take a G scale, one,
two, three, four, five, six, seven, eight.
The seventh note is the scale.
You flat it, and add it to that chord and
that creates the seventh chord.
So, here's G.
Practice going between those two.
Now go back to the C chord, and
again the beauty of the mandolin, same
thing, same shape.
First fret of the second string B flat,
instead of the C note.
Now let's look at D chord.
How do we make this into a seventh chord.
We add a C note to it.
C being the seventh note of a D scale.
1, 2, 3, 4, 5, 6, 7, 8.
The seventh note, you flatten it from a
C-sharp to a C-natural.
Then you add it to that chord, and that's
You say, well where do we use these
Well the seventh, a seventh chord is used
in, in the place of the five-chord.
You've got three principle chords and then
In the case of the key of G.
G, A, B, C and D.
D being the five.
D will become a D7 chord now.
And you'll hear it.
G chord is the one.
C chord is the four.
There's your D7, to get us back to one.
That little seventh note has a, has
tension in it because it wants to
pull very badly to that B note, as part of
that G chord.
so now we're gonna use these in a couple
