Thx TJ that helped somewhat. I now understand what a triad is and that(in the key of C)It must consist of some kind of C E and G
Ex.
Major - C-E-G
Minor - C-Eb-G
If the chord gets bigger than a triad then it must have some kind of B.
Major7 - C-E-G-B
Be careful here NJ. Key has nothing to do with naming a chord. ALL chords are built in thirds, which is the same as every other letter. So, no matter what key you are in, any kind of C chord starts with C-E-G of some sort. Just like any D chord starts with D-F-A of some sort, etc. The chords build and build on thirds until you return back to your starting note. So, using C u got:
C-E-G = C triad
C-E-G-B = C 7th
C-E-G-B-D = C 9th
C-E-G-B-D-F = C 11th
C-E-G-B-D-F-A = C 13th
C-E-G-B-D-F-A-C *ahhh, here we get back to C, so the chords only go up to 13
Same with D:
D-F-A = D triad
D-F-A-C = D 7th
D-F-A-C-E = D 9th
D-F-A-C-E-G = D 11th
D-F-A-C-E-G-B = D 13th
Now, after you get a basic understanding of how to build chords, next you need to know the formulas for each type of chord (major, minor, dim., etc.) After you know that, then knowing what kind of chord you have will be simple.
Thx T, but how do I know that something is minor such as a m7th?
I know how to minor a major, flat the 3rd(right?)
It looks like you answered your own question. Any kind of minor chord will have 1st have the flat 3rd.
So to minor a 7th would I flat it? like for the key of C the m7th would be Bb?
Yes sir.
So C-E-G-Bb would be a dom7, right?
Yes sir.
Diminished chords
Going by your rules, I have that a Cdim (is that the right notation?) is.. C-Eb-Gb
Ok then to make that a fully diminished chord, I would add an A, right? so... C-Eb-Gb-A
Yes for the 1st question. Yes and no for the second question. Although you're adding an A, make sure that you know it's a Bbb because the formula for a dim7 chord calls for a bb7.
Major 7th and on
Ok
Cmaj7 - C-E-G-B
Cmaj9 - C-D-E-G? It doesn't have the regular 7th but is it still right?
Cmaj11 - C-E-F-G? That can't be right
Maybe I should've explained that better. The Cmaj7 chord is correct. Now, in order to go higher (Cmaj 9, Cmaj 11, etc.) you have to keep that 7th there and build on it. Since the chord is major to begin with, it should be understood that you have to have the 3rd there as well. So:
Cmaj 9 = C-E-G-B-D *notice the 7th is there
Cmaj11 = C-E-G-B-D-F or C-E-G-B-F *notice the 7th is still there, but you don't have to play the 9th
Cmaj13 = C-E-G-B-D-F-A or C-E-G-B-A *notice the 7th is still there, but you don't have to play the 9th or 11th
Could you explain the augmented, dominant th's, min9 and upand maj9 and up in greater detail please.
"Bear" with me, i ask a lot of q's.
I'll explain about the minor 1st. Just like with the maj 7th and on, in order to go past min 7th, you have to keep the m7th there and build on it. Since the chord is minor to begin with, it should be understood that you have to have the flat 3rd there as well. So:
Cmin9 = C-Eb-G-Bb-D *notice the m7th
Cmin11 = C-Eb-G-Bb-D-F or C-Eb-G-Bb-F *notice the m7th is still there, but u don't have to play the 9th
Cmin13 = C-Eb-G-Bb-D-F-A or C-Eb-G-Bb-A *notice the m7th is still there, but u don't have to play the 9th or 11th
O.K., with augmented chords you will either see a + sign by the chord, or more likely you will see it represented as a #5 which means raised 5th. I mean, that is what an augmented chord is, a major chord with a raised 5.
This makes way for chords that have other weird notations like b9, #9, b11, etc. These type of notations tell you that the specific scale degree has been added and altered. So, a chord like:
C7 b9 = C-E-G-Bb-Db *C dominant 7th chord, with a flat 9th added
Notice that it starts with the C7 part of the chord, then the flat 9th is added to it. I hope that I've answered all your questions successfully. If you need any more help, just keep asking.
