A Chord and its Interval Structures

[dwest2419]

--------------------------------------------------------------------------------

I did not know that a Major chord has a major third and a minor third and a Mminor chord has a minor third then a major third. For example in the key of C

C to E = Major third and E to G = minor third
D to F = Minor third and F to A = major third

I wonder how a suspened 2nd and a suspened 4 look like? Lets try

C to D = a whole step and D to G = I think a perfect fourth???
C to F = I think a perfect fourth and F to G = a whole step

I wonder how a maj7 and min7 would look like?

As I said in the other thread, there are only 4 chord types:
major = major and minor intervals in the triad, from the 1 to the 3 and from the 3 to the 5
minor = minor and major triad intervals
diminished = minor and minor
augmented = major and major

Every other chord is a color or different character to the above 4, but they don't change the triad structure and this includes sus2 (which are really not legit chords so to speak) and sus4 (which are just temporarily modified major chords).

Hey whatsup you guys? I finally figured out about the Maj7 and Minor7 chords and how their intervals are constructed. For example, in the key of C

C E G B = C Maj7

C to E = Major third
E to G = Minor third
G to B = Major third

A C E G = A min7

A to C = Minor third
C to E =Major third
E to G = Minor third

Once I learned how chords are constructed as far there intervals, it maybe start voicing chords correctly.

Learning intervals helped me make a lot of sense out of the guitar and music in general.
My ear hears intervals and harmony pretty clearly, so I picked up the concept of intervals pretty fast.

The thing I trying to figure out is how this maj7 chord is built intervalic

Cmaj7 x35453

Notes x C G B E G

I tried to analyse the notes

C to G = Perfect fifth
G to B = Major third
B to E = Perfect fourth???
E to G = Minor third

Whereas the correct notes in correct order for a Cmaj7 would be C E G B where as creates

C to E = Major third
E to G = minor third
G to B = Major third

As you can see the difference between a real maj7 chord versus the how the notes are arranged on the guitar fretboard. Am I doing to something because it seems to me its like this for the rest of the chords aswell except triads I think.

[dwest2419]

Im sorry E to B is a perfect fifth or B to E which is the same thing

[gtrdave]

You're really overthinking this.
The intervals are what they are, it doesn't matter the order of the notes.
Cmaj7 is C - E - G - B
You can put the notes in any order that you want to...w/ the C in the bass preferably, but not necessary...if the intended chord is Cmaj7, those notes will make a Cmaj7 no matter the order.

Yea, you were right I went little overboard on this.
