Okay, so, this is what I consider a pretty simple way to figure out what chords are in a major key [minor keys eventually later]
So let's begin:
Let's start with an example using the C Major Scale.
We should know (And if you didn't, you do now)That the notes in C major are:
C, D, E, F, G, A, B, and the octave C.
And if I write them in their Roman Numerals it would be;
I, II, III, IV, V, VI, VII, VIII.
C, D, E, F, G, A, B, C .
So here is all you need to remember:
I = Major
II = Minor
III = Minor
IV = Major
V = Major
VI = Minor
VII = Diminished
If you remember that order of: "Major, Minor, Minor, Major, Major, Minor, and Diminished" You will have the basic formula for Major Key Chord Progressions.
So if we go back to our example of figuring out chords in the key of C Major, we would have our notes: C, D, E, F, G, A, B, C. and apply the one word that goes after each letter, whether it be major, minor, or diminished.
I. C Major Chord
II. D Minor Chord
III. E Minor Chord
IV. F Major Chord
V. G Major Chord
VI. A Minor Chord
VII. B Diminished Chord
See above we have the scale, C, D, E, F, G, A, B, C. In that order. And in the same order we have, Major, Minor, Minor, Major, Major, Minor, and Diminished.
So we have: C Major, D Minor, E Minor, F Major, G Major, A Minor, and B Diminished.
And there's the chords in the key of C Major!
So let's test your knowledge. Lets try to figure out the chords in G Major.
Take the G Major Scale, which is: G, A, B, C, D, E, F#, G.
And our magic formula above; Major, Minor, Minor, Major, Major, Minor, Diminished.
And try to figure out what chords are in the key of G Major. You can write it down or memorize it or whatever you do.
Okay! What did you come up with?
Hopefully it was:
Hope this lesson was informative :) Stay tuned for my next lesson on Natural Minor Scale and the chords that belong to them!
