Perfect! Those are the correct answers to the quiz.
I actually realized we should do one more thing on chords before each key. It's kind of important and I skipped over it.
Alright so we know we can make a chord triad by using the root, 3rd, 5th method.
But obviously, there's more notes in chords sometimes. What are these notes that are used?
I'm going to teach a few new ones so you know how certain chords are named.
The first chord we'll go over is the major 7th chord.
First to create it, we need a major triad:
C D E F G A B C
(C) D (E) F (G) A B C
CEG
To make a major 7th chord, in this case a Cmaj7, all we do is add another note two alphabet notes up, so another 3rd on top, or you can think of it as 7 notes from the root:
(C) D (E) F (G) A (B) C
CEGB
For it to be a maj7 chord, the last note needs be a half step from the root. B is a half step from C, which happens to be the root. The octave in which B is in doesn't matter. Actually, as long as you have all the notes that belong to the chord, it doesn't matter what order the notes are or which note is the highest. For example:
CEGB = EGBC = GBCE = etc.
But the notes have to line up alphabetically, every other note when you rearrange it.
So now the next chord is pretty important. Let's take a C major 7th chord:
CEGB
(C) D (E) F (G) A (B) C
So now if you take the 7th note, which happens to be B, you get an entirely new chord:
CEGB ---> Flat the 7th ----> C-E-G-Bb
This is now a Dominant 7th chord. You've probably seen it notated as:
C7, D7, A7
Basically, it's a chord with a note that's 7 alphabetic notes from the root, and it's a whole-step down from the root.
C-E-G-Bb would be called a C7 chord.
It has a few functions. One, it's used to embellish the V-I relationship. That extra note added in creates more tension, or so a build up to the main chord in the song, which is ALWAYS the I chord.
It's also used as the man chord found in blues songs. For example a blues chord progression might look like:
I7 - IV7 - V7 - I7
A7 - D7 - E7 - A7
Minor chords also function the same way with 7ths.
Let's take an A minor chord:
(A) B (C) D (E) F G A
ACE = A minor
Use the same rule and add the note that's 7 notes from the initial note/root:
(A) B (C) D (E) F (G) A
ACEG = Amin7
Basically, in a minor chord, you add the 7th note from the root, and it has to be a whole step from the root.
There are other kinds of 7th chords, including diminished, but there's no need to teach you those right now. They wouldn't be of any use to you. If you ever want to learn them I can teach them to you, but for now we'll skip over them.
================================================== ======
There are also other kinds of chords you should know.
When you take a major chord, and you add in a note that's 6 notes from the root, that's called a 6 ("six") chord. A C6 chord would look like this
C major
(C) D (E) F (G) A B C
Add in a 6th....
(C) D (E) F (G) (A) B C
CEGA = C6
There's also suspended chords. There are two types you'll need to know for now. These are sus2 and sus4.
Sus2 is when you add in the next note that's after the root, or the 2nd note. You also delete the 3rd. Sometime people don't, but I do because I like the sound of it. You a Here's an example.
Csus2
(C) (D) (E*) F (G) A B C
CD(E)G
*Using the 3rd is optional in a suspended chord. Most suspended chords don't use them.
A sus4 is basically the same thing, but instead you throw in the 4th note in the scale and throw out the 3rd
(C) D (E) (F) (G) A B C
C (E) F G
================================================== =====
There's also an add chord. It's closely related to a suspended chord, but there is a difference.
An add chord is when you add in an odd numbered note that's above the root, and is beyond the 7th note, so these notes are usually 9, 11, or 13 notes above. You really never see anything past that.
So if we add in the note that's 9 above the root:
(C) D (E) F (G) E B C (D) E F
CEGD = Cadd9 chord
And add 11 chord is when you add the 11 above the root:
(C) D (E) F (G) E B C D E (F)
CEGF = Cadd11 chord
And for an add13...
(C) D (E) F (G) E B C D E F G (A)
CEGA = Cadd13
===============================================
As you notice, some of the add chords have the same notes as the suspended chords:
Csus2 = CEGD
Cadd9 = CEGD
To distinguish the difference, suspended chords throw out the 3rd note and replace it with the 2nd, while an add chord retains the entire triad.
Csus2= CDG
Cadd9= CEGD
Same with
Csus4 = CFG
Cadd11 = CEGD
One last thing........
This is still a C major chord:
(C) D E F (G) A B (C) D (E) F G A B (C) D (E) F (G) A B C
Even though it's CGCECEGC and it's really spaced out, it fundamentally has the chord tones of a C major chord. So as long as it's all the right notes, the order in which you play them, and the octaves that they are don't matter.
This chord ----> CGCECEGC is still a C major chord because it has CEG. Get it?
This concept works the same with all chords, major, minor, etc.
Alright so next post, we will start studying different keys of music!
