Maybe a noob question...
How do you determine what chords are in a Key?
#2
Learn to harmonise the major scale:

I major, ii minor, iii minor, IV major, V major, vi minor, vii dim
#3
Oh yeah, no I feel dumb, It just progresses.
Just to make sure, if it was and A key it would be A Major, B minor, C minor, D Major, E Major,F minor, then G Diminished.

that would be if key was "C"

C Major D minor E minor F Major G Major A Minor B Diminished

if key is "A" then it would be:

A Major B minor C# minor D Major E Major F# Minor G# Diminished

am I right? can someone confirm?

Gacel, Those chords (you quoted) aren't in the key of C. The ones you posted are though. You have the chords in the key of A right as well.


edit: TS, if you have a specific question (a follow-up) or something i'll be glad to help.

So is it supposed to be the Root first then a whole step, whole step, half step, whole step, whole step, whole step, half step?

Those are the steps to the major scale.


The chords in a key go in this order: Major, minor, minor, Major, Major, minor, diminished.

In C this would make: Cmaj, Dmin, Emin, Fmaj, Gmaj, Amin, Bdim

The notes to each chord go like this:
Cmaj: C,E,G
Dmin: D,F,A
Emin: E,G,B
Fmaj: F,A,C
Gmaj: G,B,D
Amin: A,C,E
Bdim: B,D,F

Notice how all of those notes are in the key of C? That's why those chords are in the key of C.

Heres some things you should know to understand your original question

- know your scales and key signatures

- know the chord types built on each scale step


Example:

Key of A major has 3 #'s (F C G)

A Major scale: A B C# D E F# G#

chord types for the Major scale

Major minor minor Major Major minor diminished

* these are triads. when you harmonize with 7ths the last chord is a "half diminished"
suggestion: stick with triads for now

A Major scale harmonize =

A major B minor C# minor D Major E Major F# minor G# diminished.

so those are the chords in A major.


If you were in C:

C Major D minor E minor F Major G Major A minor B diminished

IN G:

G Major A minor B minor C Major D Major E minor F# diminished


Hope that helps.

Amajor would be

AMAJ Bmin C#min DMAJ EMAJ F#min G#dim0

A has 3 sharps

how you figure it out IF you know what chords they are, go like so to start until you get the feel for it:


Fmaj7(could be): F or C

Am7(could be): G F or C

Gm7(could be): F Eb Bb

C7: F

Fmaj7: F C

by process of elimination the answer is F major, now to determine whether it's minor or major depends 99% of the time on if the progression resolves on a minor(relative minor or 6th chord) or major(root note or I chord). This should help you
