The only advantage knowing that 'C major is C, E and G' gives is in talking about it, beyond that it is of no use.
I am flabbergasted by this statement.
There is very good reason to know the notes in each chord and more particularly the notes in each chord as they relate to the current key/scale/mode.
We can reduce the action to a formula for each chord type and most texts do this to some extent.
Knowing what notes are in use allows us to consider novel movement such as:
Am[sup]7[/sup] - F[sup]#[/sup]m[sup]7[/sup]
On the face of it these two chords are entirely unrelated.
We can however assert the following conceptual relationship
A-A
C-C[sup]#[/sup] (semitone up)
E-E
G-F[sup]#[/sup] (semitone down)
and functional relationships
Tonic minor 7 from the natural minor moving to the parallel major sub-mediant i.e. i[sup]7[/sup]-vi[sup]7[/sup]

Minor chord = root + minor third + major third
Major chord = root + major third + minor third
No,
Minor chord is minor 3rd plus perfect 5th above the same root note
Major chord is major 3rd plus perfect 5th above the same root note
Now in a major key, 1,4 and 5 are major chords
2,3,6 are minor chords
and 7 is diminished
almost fair enough
the chords built above scale degrees 1, 4 and 5 are major chords and are shown as I, IV and V
the chords built above scale degrees 2, 3 and 6 are minor chords and are shown as ii, iii and vi
the chord built above scale degree 7 is a diminished triad and is shown as vii[sup]b5[/sup]
In a minor key 1, 4, 5 are minor
3, 6, 7 are major
2 is diminished
almost fair enough
- In the natural minor
- the chords built above scale degrees 1, 4 and 5 are minor chords and are shown as i, iv and v
- the chords built above scale degrees [sup]b[/sup]3, [sup]b[/sup]6 and [sup]b[/sup]7 are major chords and are shown as [sup]b[/sup]III, [sup]b[/sup]VI and [sup]b[/sup]VII
- the chord built above scale degree 2 is a diminished triad and is shown as ii[sup]b5[/sup]
- In the harmonic minor
- the chords built above scale degrees 1 and 4 are minor chords and are shown as i and iv
- the chords built above scale degrees 5 and [sup]b[/sup]6 are major chords and are shown as V and [sup]b[/sup]VI
- the chords built above scale degrees 2 and 7 are a diminished triad and are shown as ii[sup]b5[/sup] and vii[sup]b5[/sup]
- the chord built above scale degree [sup]b[/sup]3 is an augmented triad and is shown as [sup]b[/sup]III[sup]#5[/sup]
- In the melodic minor
- the chords built above scale degrees 1 and 2 are minor chords and are shown as i and ii
- the chords built above scale degrees 4 and 5 are major chords and are shown as IV and V
- the chords built above scale degrees 6 and 7 are a diminished triad and are shown as vi[sup]b5[/sup] and vii[sup]b5[/sup]
- the chord built above scale degree [sup]b[/sup]3 is an augmented triad and is shown as [sup]b[/sup]III[sup]#5[/sup]
So now you can find chords that fit with anything if you know the scale.
If you're in C Major you know that it is C, D, E, F, G, A, B, C
If you wanted to play chords to go with whatever melody you have you know that
C = Major
D = Minor
E = Minor
F = Major
G = Major
A = Minor
B = Diminished
Now you can play with voicing or whatever and you gotta pick whatever progression you want but that is the basics of the basics. I'm sure bandcoach can find something wrong with what I said
It is not that I seek to find the wrong but to correct the incorrect and point the way to a common language for discussing the concepts.
