    Fm6 Chord - Root Position - Piano Diagram

    The Fm6 is a chord made up of four notes F, Ab, C, and D. It’s the minor chord built on the key of F with an added major 6th interval (D). It belongs to the chord family of “added tone chords” (aka “add chord”) because it has an extra tone added to a minor triad. In this article, we’ll take a closer look at the music theory behind this chord.

    Fm6 Chord Equivalencies

    Rearranging the notes of a chord can lead to interesting and unique chord equivalencies. This is especially true for 6th chords, as we can create a different type of chord by rearranging the notes of a minor 6th chord in a specific way.

    If we take the 3rd inversion of a minor 6th chord, where the 6th note becomes the root note, we end up with a minor 7th flat 5th chord (also known as a half-diminished chord).

    For example, let’s take the Fm6 chord, which consists of the notes F, Ab, C, and D. By rearranging the notes so that D becomes the root note, we get a Dm7b5 chord with the notes D, F, Ab, and C.

    3rd Inversion of Fm6 = Dm7b5

    The reason why the 3rd inversion of a minor 6th chord results in a minor 7th flat 5th chord is due to the note relationships between the chords. When we move the 6th note to become the root note, we end up with a chord that has a minor 3rd, diminished 5th, and a minor 7th interval. These intervals are exactly the same as a m7b5 chord.

    Also, note that the 3rd inversion of a minor 6th chord is a dominant 9th chord without root. In fact, Fm6 3rd inversion is D, F, Ab, C which could be considered also a Bb9 (Bb, D, F, Ab, C) without the root.


    Music Theory and Harmony of Fm6

    An F minor 6th chord consists of four notes, an F minor triad, plus a 6th interval. Due to the inclusion of the major sixth interval, represented by the note D, the F minor 6th chord generates a sense of tension that can either be resolved by transitioning to a more stable chord or utilized to create a feeling of “uncertain stability.”

     

    Building the Fm6 Chord: Different Approaches

    Starting from the F Major Scale

    To build a minor 6th chord, you would include the root note, minor third, fifth, and sixth from a minor scale.

    However, when teaching this concept, it can be more effective to demonstrate its construction using a major scale. This is because a major scale better illustrates the relationship between intervals and their respective qualities.

    For instance, to build the Fm6 chord, you can start with the F Major scale:

     

    F Major Diatonic Scale up to octave
    F Major Scale

     

    F Major Diatonic Scale up to 13th - Keyless Notation
    F Major scale – Keyless Notation

     

    To create an Fm6 chord, apply the formula R, m3, 5, 6 in the following manner:

    1. Begin with the Root note, F.
    2. Select the 3rd interval A then lower it down by a half-tone to get the minor 3rd, Ab.
    3. Include the 5th note, which is C, to the chord.
    4. Finally, add the 6th interval, D.

    By following this simple formula, you can create a minor 6th chord from any major scale.

     


    by Combining Intervals

    One method to create a minor 6th chord is by combining specific intervals – a minor 3rd, a major 3rd, and a major 2nd (a whole-tone).

    m3 + 3 + 2 = minor 6th Chords

    To illustrate, let’s use the Fm6 chord as an example: by examining the intervals between the notes, we can see that

    • F-Ab is a minor 3rd interval,
    • Ab-C is a major 3rd interval,
    • and C-D is a whole-tone interval.

    These three intervals can be stacked together to create the Fm6 chord.

     


    How to Use Fm6 in a Chord Progression

     

    A minor 6th chords can be used as a variation of a minor chords. However, it’s important to understand that the major 6th interval present in this chord may not always be a part of the scale being used.

    • Non-diatonic Mediant chord in Db Major
    • Non-diatonic Submediant chord in Ab Major
    Non-diatonic positions

    In the case of the F minor 6th chord, the D does not exist in either the F natural minor scale or the Ab major scale. This is why the F minor 6th chord (and any other chords with non-scale tones) are called “non-diatonic.”

    As a result, it is possible that the inclusion of this chord could cause dissonance within a melody or harmonic progression. So, just be careful when you use this chord in your music. Make sure it works well with the other chords and notes so that it makes the whole piece sound better.

     


    Fm6 Function in Major and Minor Keys

    Understanding Scale Degrees

    Scale degrees are essential for understanding the relationship between the notes in a scale and how they function within chords. The diatonic major scale consists of seven degrees, each with its unique role in creating the overall harmony of the scale.

    1. The first degree of the scale is known as the Tonic, which serves as the anchor for the music. It establishes a stable tonal center that acts as the foundation for the scale.
    2. The second degree is called the Supertonic, often used as a transitional note between the Tonic and other notes in the scale. It creates a sense of motion within the melody or harmony.
    3. The third degree of the scale is the Mediant, which sits halfway between the Tonic and Dominant notes. It helps establish whether the scale is major or minor.
    4. The fourth degree is called the Subdominant, used to complement the Dominant and add tension and resolution to the music.
    5. The fifth degree is the Dominant, which creates tension and anticipation within the melody or harmony, typically resolved by returning to the Tonic.
    6. The sixth degree is the Submediant, often employed as a transitional note between the Dominant and Tonic, adding a sense of stability and restfulness to the music.
    7. The seventh degree is the Leading tone, located one half-step below the Tonic. It creates a strong sense of tension and a desire to resolve to the Tonic, frequently used to create a sense of resolution and finality in the melody or harmony.

     


    Fm6 in F minor (Non-Diatonic)

    The F minor 6th chord is a unique and intriguing option as the tonic chord in the F natural minor scale, as it creates a complex and ambiguous harmonic center. The presence of the major 6th interval (D) adds tension and dissonance to the chord, creating a sense of instability and uncertainty.

    However, since D is not included in the scale, the Fm6 may clash with the melody, bass line, or other elements of the music. This dissonance can be used to create a sense of tension, but it can also make the chord difficult to use in certain musical contexts.

    Non-diatonic chords, as the Fm6 in this case, can be used to modulate between keys or to add harmonic color and contrast to a composition. It can be used as part of a chromatic modulation to move to a related key or to create a sense of chromaticism within the natural minor scale.

    Fm6 in Bb minor (Non-Diatonic)

    The Fm6 chord can also function as a variation of the dominant chord in the Bb natural minor scale. When used as a dominant minor chord in a minor key, the Fm6 creates a tense and unresolved sound that conveys a feeling of instability and urgency.

    This chord generates a sense of anticipation and tension in the music as if it is leading somewhere and needs to resolve to the tonic chord (Bb min) to provide a sense of closure.

    In this way, the dominant minor chord acts as a musical bridge that connects the other chords in the progression to the tonic. It contrasts with the tonic chord by creating tension and movement, while the tonic chord represents stability and resolution.

    Fm6 in Eb Major

    Besides its use in natural minor scales, the Fm6 chord can also be played in major keys. In the key of Eb major, for instance, the Fm6 chord functions as the supertonic chord, located on the second degree of the scale.

    A supertonic minor 6th chord in a major key produces a slightly tense and unresolved sound, creating a feeling of anticipation or expectation as it typically leads to the dominant or subdominant chords.

    Fm6 in Db Major (Non-Diatonic)

    In addition to its positions in natural minor scales and major keys, the Fm6 chord can also function as the mediant (iii) chord in the key of Db major, located on the third degree of the scale.

    The mediant minor chord creates a temporary tonal ambiguity or departure from the established tonality of the key before returning to the tonic chord.

    Fm6 in Ab Major (Non-Diatonic)

    The Fm6 chord can be played on the sixth degree of the Ab major scale, functioning as the submediant chord. The submediant chord is typically characterized by a feeling of relaxation and stability in a chord progression.

    However, when the chord is formed using a major 6th interval, it can create a sense of uncertainty or ambiguity. This can add an interesting twist to the otherwise stable and calming effect of the submediant chord.

    Conclusion

    The chord progressions and examples presented in this post provide a comprehensive overview of the most common uses of the F min6 chord. It’s important to note, however, that many advanced harmony-related topics could not be included due to space constraints. These topics include chord progressions built on harmonic and melodic scales, modal scales, hidden tonality, secondary dominants and other chord substitutions, non-functional harmony and atonal music, modal interchange and borrowed chords, voice leading and counterpoint, chromatisms, jazz harmony…I mean, music theory is a huge topic!

    Although I couldn’t cover all of these topics in my post, I encourage readers to continue exploring these areas in their study and research. By expanding your knowledge in these advanced areas of music theory, you can gain a deeper understanding of the harmonic possibilities that exist beyond the basics presented here.
