Minor Chord Substitution

Chord Substitution is common in our music today.

We can replace a chord with another related chord.

Often the substituted chord differs by one or two notes from the original chord.

Before you read this post, it will be good to take a look at my previous lesson - Introduction to Chords Substitution

For example, we can replace an Am7 chord with a Fmaj7 chord.

The notes in the Am7 chord are: A C E G

In the Fmaj7 chord the notes are: F A C E

There is only one note difference between these two chords.

If we have an Em7 chord, we can replace it with a Cmaj7 chord.

You can also replace the Em7 chord with a Gmaj7 chord.

The notes in the Em7 are: E G B D and G B D F# for Gmaj7.

Again the difference is only in one note. You can call this a relative chord.

Hope this helps.

Introduction to Chords Substitution

Hi,

This post is an attempt to understand basic chords substitution.

This is useful when the chords for both the verse and chorus of a song are the same.

Let's list down the chords in G major.

I II III IV V VI VII
Gmaj7 Am7 Bm7 Cmaj7 D7 Em7 F#m7(b5)

For example, the chords of a song uses I VI IV V progression.

The chords will be Gmaj7 Em7 Cmaj7 D7.

We can substitute I with III.

Instead of playing Gmaj7, we change to Bm7.

The new progression will be Bm7 Em7 Cmaj7 D7

The notes in a Gmaj7 are G B D F#

The notes in a Bm7 are B D F# A

Out of 4 notes, 3 are the same, therefore it will sound correct.

Hope this helps.

Have fun.
