    Our lesson today is on chord substitution and we’ll be exploring 9 substitutes for the 1-chord in the major key.

    One of the chords that is commonly played in tonal music is the 1-chord and this is because most songs start out and end on the 1-chord. Sometimes, there is need to substitute the 1-chord with other chords (especially chromatic chords) that are sophisticated.

    Using what I call the “3-5-7-9” principle (that we covered in a previous post), you can derive 9 chord substitutes that can fit into the same position where the 1-chord fits into; especially at the end of the song.

    Let’s get started by refreshing our minds on the concept of chord substitution.

    A Short Note On Chord Substitution

    If you’re tired of using the same set of chords over and over again, and are interested in replacing those chords (whether boring or spicy) with other chords, then this lesson is for you.

    The concept of chord substitution is concerned with the replacement of a given chord with another chord which may either foreign or related.

    The same way soccer players are substituted during tournaments, chords can also be substituted. The 1-chord (which is our focus in this lesson) plays a vital role in harmony and I’ll be showing you quite a number of chord substitutes it can be replaced with.

    Although there are so many approaches to chord substitution, we’ll be using the 3-5-7-9 approach to chord substitution;

    In the “3-5-7-9” approach to chord substitution, the first, third, fifth, and seventh tones of a given major ninth chord are considered as the third, fifth, seventh, and ninth tone of another major ninth chord.

    Final Words

    Apart from the F major ninth substitute, the rest of the chords covered in this lesson are chromatic.

    Therefore it is recommended for you to practice the application of these substitutes because the use of chromatic chords to substitute the 1-chord requires experience.

    Keep up the good work!
