Knowing how to build chords and chord progressions is a really great tool for writing your own songs and communicating with your fellow musicians on how to play a certain piece of music, “Let’s play a 1 4 5 progression in the key of…”
You can create the most beautiful chord progressions and songs by ear and you don’t necessarily need to know music theory for that, but it makes the life of a musician a lot easier if you do know some music theory on this part.
It’s nice to know what other musicians are talking about and how you can create chord progressions in a more effective and efficient way.
Adding music theory knowledge will reveal a lot of secrets you wish you had known before, so don’t wait for later or you’ll miss out on all the good stuff. Music theory will definitely make you a better musician!
Now let’s dive in:
From the major scale you can build 7 diatonic chords. The major scale consists of 7 notes, so that’s one chord of each note.
Let’s take the C major scale for example.
C D E F G A B + C (=octave)
To build the first chord “C” of the major scale we stack thirds on top of each other. So if you start at “C” you take the 1st note (stack a third), 3rd note (stack another third) and the 5th note of the major scale: C E G
C E G = C Major
Then we build a chord of the second degree of the major scale “D”
Again from the D chord we stack thirds on top of each other.
So from “D” take the 1st, 3rd and 5th note = D F A
D F A = D minor
Build a chord from the 3rd degree of the major scale “E”
Stacking thirds: E G B
E G B = E minor
Chord from 4th degree is “F”, stacking thirds: F A C = F Major
Chord from 5th degree is “G”, stacking thirds: G B D = G Major
Chord from 6th degree is “A”, stacking thirds: A C E = A minor
Chord from 7th degree is “B”, stacking thirds: B D F = B diminished
So we got:
C major, D minor, E minor, F major, G major, A minor and B diminished.
All these chords can be used if you’re playing a chord progression in the key of “C”
Now we can derive a formula from this pattern of chords.
Formula for finding chords in a major scale:
1=Major, 2=minor, 3=minor, 4=Major, 5=Major, 6=minor, 7=dim
This formula can be applied to every key.
For example if you take the G major scale: G A B C D E F#
Apply formula and you get these chords:
G Major, A minor, B minor, C Major, D Major, E minor, F#dim
So if you wanna write a song or a chord progression in the key of G you can use all these chords randomly and they will all sound perfectly well together.
BUILDING CHORD PROGRESSIONS:
In music we use roman numerals to indicate the order of chords in a chord progression.
So let’s take the chords built of the G Major scale for example:
I = G Major, ii = A minor, iii = B minor, IV = C Major, V = D Major, vi = E minor and vii = F#dim.
Now we can build chord progressions with these roman numerals. Here are some of the most common chord progression in pop, folk, country and rock music. With these chord progressions thousands and thousands of hit songs were written and that will probably be the case for decades to come.
Progression: I – V
In the key of G that is = G D
In the key of C that is = C G
Song examples: Jambalaya – Hank Williams, Dance the night away – The Mavericks
Progression: I – IV – V
In the key of G that is = G C D
In the key of C that is = C F G
Song examples: La Bamba – Ritchie Valens, Twist and shout – The Beatles
Progression: I – IV – I – V
In the key of G that is = G C G D
In the key of C that is = C F C G
Song examples: Free fallin’ – Tom Petty, brown eyed girl – Van Morrison
Progression: I – vi – IV – V
In the key of G that is = G Em C D
In the key of C that is = C Am F G
Song examples: Stand by me – Ben E King, Every breath you take – Sting, Love hurts – Everly Brothers
Progression: I – V – vi – IV
Key of G = G D Em C
Key of C = C G Am F
Song examples: You’re beautiful – James Blunt, I’m yours – Jason Mraz, With or without you – U2
Progression: vi – IV – I – V
Key of G = Em C G D
Key of C = Am F C G
Song examples: The other side – RHCP, Zombie – The Cranberries, One of us – Joan Osbourne
Now write your own song with the help of these chord progressions. Have fun!
