subject: Guitar For Kids -- The B7, C7, D7, E7 And G7 Chords [print this page] Hi everyone! Hi everyone!
Today, we are gonna learn about the B7, C7, D7, E7 and G7 chords.
In our last lesson about the A7 chord, we learned that in order to create your standard, garden variety 7th chord -- also known as a dominant 7th -- we need to add another m3 (minor 3rd) to the regular R 3 5 that makes up any basic chord. We then learned the A7 chord (A C# E G).
Now let's deal with some more. First the B7 chord.
To do this, first we start with the notes of the B chord which are B D# F# (R + M3 + m3).
Now we have to add another m3 to this puppy to get the 7th chord. Seeing how a minor 3rd is equal to 3 half-steps, this note will be an A. So the B7 chord is:
B D# F# A (R 3 5 7) OR (R M3 m3 m3)
Check out the chord fingering. Make sure that all of the notes are clear. No thuds allowed!
[ x 2 1 2 0 2 ]
If we do this for the rest of the chords, we find:
C7 = C E G Bb
D7 = D F# A C
E7 = E G# B D
G7 = G B D F
By the way...Didja notice that the dominant 7th (or just 7th) is also 1 step down from the octave of the root?
Octave? Wazzat?
C D E F G A B C (octave of C)
Thazwat.
Note the fingerings below. Did ya'll notice that there are 2 different ways of playing an E7 chord in the open position?
C7 [ x 3 2 3 1 0 ]
D7 [ x 0 0 2 1 2 ]
E7 short form [ 0 2 0 1 0 0 ]
E7 long form [ 0 2 1 1 3 0 ]
G7 [ 3 2 0 0 0 1 ]
Now as always, practice switching these chords with the other chords that you know.
Alright... Now how do we use these here new-fangled chords?
Here are some often-used examples. I'll use the key of G to start out with:
G G7 C C7 D D7 G
G C D7 G
G7 C7 D7 G7
G Em Am D7 G
G Bm C D7 G
To show you guys how to do these in all major keys, I'll use that roman numeral convention thingy that I taught you earlier:
I I7 IV IV7 V V7 I
I IV V7 I
I7 IV7 V7 I7
I vi ii V7 I
I iii IV V7 I
Practice these and get a feel for how they sound. Start listening to recordings and see if you can hear these types of chord changes.
See ya later!
