F6 Piano Chord

Piano Diagram of F6 in Root Position

F6 is a four-note chord consisting of the notes F, A, C, and D. It is a major chord with an added sixth. It belongs to the chord family of “added tone chords” (aka “add chord”). Keep reading to gain a deeper understanding of the music theory behind this chord.

Music Theory and Harmony of F6

Building the F6 Chord: Different Approaches

Starting from the F Major Scale

To create a 6th chord, you can use the Major scale as a reference by combining a Root, a 3rd, a 5th, and a 6th.

 

 

 

Apply the formula R, 3, 5, 6 to build a 6th chord:

1. Select the Root note, which is F.
2. Pick the 3rd note, which is A, and add it to the chord.
3. Add the 5th note, which is C, and include it as well.
4. Finally, add the 6th which is D.

by Combining Intervals

To build a 6th chord, one approach is to combine specific intervals, namely a major 3rd, a minor 3rd, and a major 2nd (a whole-tone).

3 + m3 + 2 = 6th chords

For instance, when building an F6 chord, you can observe that

• F-A forms a major 3rd interval,
• A-C creates a minor 3rd interval, and
• C-D makes up a whole-tone interval.

By stacking these intervals together, you can form an F6 chord.

6th Chords Equivalencies

If we take the third inversion of a 6th chord (which means we move the notes around so that the 6th note becomes the Root note), we end up with a new chord that is equivalent to a min7 chord.

So, if we take the F6 chord (which has the notes F, A, C, and D) and move the notes around so that D becomes the Root note, we end up with a new chord that is equivalent to a D min7 chord (which has the notes D, F, A, and C).

3rd inversion of F6 = D min7

How to Use F6 in a Chord Progression

 

Since 6th are based on major triads with an extra sixth, they can substitute the major chords built on the scale of the root. This means that we can use the F6 chord in those positions on the scale where the harmonization results in a major chord.

This table showcases the harmonized major and natural minor scales where an F Major chord can be found. In all positions where an F Maj7 chord is present, the F6 chord can be used as a variation.

on Major Scales

• Tonic chord in F Major
• Subdominant chord in C Major

on Natural minor Scales

• Mediant chord in D minor
• Submediant chord in A minor

F6 in F Major

The 6th interval is a consonant interval, which means it doesn’t create any tension that needs to be resolved. It’s stable and often used as a substitute for the tonic chord, which is usually the main chord in a musical piece.

The A6th chord can be used instead of an F major (or F major 7th chord), which is the first chord in the harmonized F major scale.

In a major key, the I chord (built on the first degree of the major scale) serves as the tonic chord, providing the harmonic center of the chord progression.

 

F6 Chord Progressions as I degree

Replacing a standard major chord with a 6th chord can enhance the richness and complexity of your music. Here’s a chord progression that demonstrates how the F6 chord can function as a substitute for the tonic (I degree) in a chord progression:

 

II V I

 

I IV V

 

I V vi IV

 

I IV vi V

F6 in C Major

The F6 chord can also be used as the fourth degree of the C major scale as a substitute for the F Maj7. When applied to the I-IV-V progression, this chord on the fourth degree acts as a transitional chord between the first and fifth degrees.

Try playing these chord progressions to get an idea of how F6 functions as a substitute for the subdominant (IV degree) in a chord progression.

F6 in D minor

Similarly, in D minor, the F6 chord can be used as a substitute for the F Maj7 chord on the third degree.

 

F6 as III degree – Chord Progressions

These chord progressions show the F6 chord as a substitute for the mediant (III degree) chord.

F6 in A minor

In the key of A, you can also substitute an F6 chord for an F Maj7 chord when the F Maj7 chord appears on the sixth degree of the A minor scale. This is another situation where the F6 chord can be used as a replacement.

 

F6 as VI degree – Chord Progressions

You may want to experiment with these chord progressions to understand how the F6 chord can be used instead of the F Maj7 chord when it acts as the submediant (VI degree) in an A minor scale.
