    Fm13 Chord - Root Position - Piano Diagram

    The Fm13 chord is built upon the root note F and includes a minor 3rd (Ab), a perfect 5th (C), a minor 7th (Eb), a major 9th (G), an 11th (Bb), and a 13th (D). This chord bears resemblance to a minor 6th chord due to the presence of the 13th, which is essentially a 6th note played at a higher octave. However, it also includes a minor 7th, major 9th, and 11th notes, which contribute to creating a sense of tension and dissonance.

    Playing Extended Chords on Piano

    Extended chords like the Fm13 can be challenging to play due to the large number of notes they involve. To simplify them, pianists often use different strategies like omitting certain notes or dividing the chord between both hands.

    How to play an Fm13

    When playing an Fm13 chord, you can play the root note F with the left hand and use the right hand to play the minor 7th note Eb, the 9th note G, and the 13th note D. This way, you can play a simplified Fm13 chord that includes only the root note, minor 7th, 9th, and 13th notes:

    F + Eb, G, D

    Another option is to play the root note with the left hand and use the right hand to play an inversion of the chord with the 7th note (Eb), the minor 3rd note (Ab), and the 13th note (D):

    F + Eb, Ab, D

    Also, you could play an Fm13 just playing the root note with the left hand and the 9th, the 3rd, and the 13th with your right hand:

    F + G, Ab, D

    Despite using these techniques, extended chords can still produce dense and complex harmonies. When the chords are inverted, the resulting clusters of notes can be particularly challenging to play effectively and require careful voicing.

     

    Fm13 Chord Inversions

     

    The Fm13 chord has a total of 6 inversions:

    Root Position: F Ab C Eb G Bb D
    1st Inversion: Ab C Eb F G Bb D
    2nd Inversion: C Eb F G Ab Bb D
    3rd Inversion: Eb F G Ab Bb C D
    4th Inversion: G Ab Bb C D Eb F
    5th Inversion Bb C  D Eb F G Ab
    6th Inversion  D Eb  F  G  Ab Bb C

    Chord Inversion on Piano

    Having a solid understanding of chord inversions is a crucial element of music theory since it sheds light on how chords are constructed. When it comes to playing chord inversions on a piano, it’s essential to keep in mind that the charts and graphs depicting the order of notes may not always be feasible or even playable.

    To achieve the proper chord voicings on a piano, you must spread the chord notes across various octaves and positions on the keyboard. This often entails deviating from the typical shape of the chord’s inversions shown in charts, which may not be the most practical or comfortable way to play the chord.

    While chord inversion charts can help understand the structure and sequence of notes in a chord, it’s always a good idea to experiment with different voicings and fingerings to find the most efficient and comfortable way to play the chord, while still preserving its intended harmonic function and sound.


    Music Theory and Harmony of Fm13

    The Fm13 chord is a diatonic extension of Fm7. While it can be substituted for the Fm7 chord in any position, it is commonly used in conjunction with it. Nonetheless, it’s worth noting that certain positions may not be as effective when substituting Fm13 for Fm7.

     


    Building the Fm13 Chord: Different Approaches

    Starting from the F Major Scale

    To build a minor 13th chord, you would typically combine the root note, minor 3rd, 5th, minor 7th, major 9th, 11th, and 13th from a minor scale. However, for educational purposes, it may be clearer to demonstrate its construction using a major scale, as it better illustrates the relationship between intervals and their qualities.

    To build an Fm13, you can start with the F Major scale:

     

    F Major Diatonic Scale up to 13th

    F Major Scale

     

    F Major Diatonic Scale up to 13th - Keyless Notation

    F Major Scale – Keyless Notation

     

    To create an Fm13 chord, apply the formula R, m3, 5, m7, 9, 11, 13 in the following way:

    1. Begin with the Root note, F.
    2. Select the 3rd interval, A then subtract a half-step to get the minor 3rd Ab.
    3. Add the 5th interval, C.
    4. Select the 7th interval, E, and lower it down by a half-step to get the minor 7th, Eb.
    5. Add the major 9th, G.
    6. Pick the 11th Bb, which is a 4th interval at the higher octave.
    7. Lastly, add the 13th (D) which is a 6th at a higher octave.

    By following this simple formula, you can create a minor 13th chord from any major scale.

     


    by Combining Intervals

    One method to create a minor 13th chord is by combining specific intervals – a minor 3rd, a major 3rd, a minor 3rd, a major 3rd, a minor 3rd, and a major 3rd. This is the formula:

    m3 + 3 + m3 + 3 + m3 + 3 = minor 13th Chords

    Upon analysis of the Fm13 chord, we can note that:

    • the interval between F and Ab is a minor 3rd,
    • between Ab and C is a major 3rd,
    • between C and Eb is a minor 3rd,
    • between Eb and G is a major 3rd,
    • between G and Bb there is a minor 3rd,
    • and finally, between Bb and D there is a major 3rd.

     


    by Combining Chords

    Another way to build minor 13th chords is by combining a minor triad with a Maj 7th chord derived from its minor 7th, or by merging a minor 7th chord with a minor triad that is based on its second interval.

    To build an Fm13 chord, you can blend an F minor triad (F, Ab, C) with an Eb Maj7 chord (Eb, G, Bb, D) or an Fm7 (F, Ab, C, Eb) with a G minor (G, Bb, D).

    Fm + Eb Maj7 = Fm13

    or

    Fm7 + G min = Fm13

     


    How to Use Fm13 in a Chord Progression

     

    The F minor 13th chord is a more complex version of the F minor 7th chord, as it includes additional notes such as the 9th, 11th, and 13th. These extra notes add a lot of dissonance and tension to the chord, which can make it tricky to use in a chord progression. Even if you leave out some of the notes, you still need to find the right voicing, because the effect of the Fm13 depends on how it fits in with the other chords. It’s important to experiment with different voicings and figure out what works best with your particular progression.

    In this post, we will focus just on the most common uses of the Fm13 chord. The tables of the major and minor keys below include the F minor 7th chord, which can be substituted or complemented by an F minor 13th chord.

    • Supertonic chord in Eb Major
    • Non-diatonic Mediant chord in Db Major
    • Submediant chord in Ab Major
    Non-diatonic positions in Bb minor and Db Major

    It’s important to note that the major ninth interval G clashes with the Gb note found in both the Bb minor and Db major scales, as they are only a half step apart. As a result, it’s generally recommended to avoid using F minor 13th in these particular positions. However, rather than simply telling you to avoid it altogether, I believe the best approach is to test the dissonance of the Fm13 chord in those positions and make a judgment call based on your own preferences.

     


    Fm13 Function in Major and Minor Keys

    Understanding Scale Degrees

    Understanding scale degrees is essential for comprehending the relationship between the notes within chords and how they function. The diatonic major scale consists of seven degrees, each with a distinct role in shaping the overall harmony of the chords.

    1. The first degree of the scale is the Tonic, serving as the foundation for the chord progression. It establishes a stable tonal center, providing an anchor for the rest of the chords in the progression.
    2. The second degree is called the Supertonic, often used to create a sense of motion within the chord progression. It acts as a transitional chord between the Tonic and other chords in the progression.
    3. The third degree of the scale is the Mediant, sitting halfway between the Tonic and Dominant chords. It helps determine whether the chord progression is major or minor.
    4. The fourth degree is the Subdominant, complementing the Dominant and adding tension and resolution to the chord progression.
    5. The fifth degree is the Dominant, creating tension and anticipation within the chord progression, typically resolved by returning to the Tonic.
    6. The sixth degree is the Submediant, often employed as a transitional chord between the Dominant and Tonic, adding a sense of stability and restfulness to the chord progression.
    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 chord progression.

    Conclusion

    The chord progressions and examples in this post give a comprehensive overview of the common uses of the Fm13 chord. However, it’s important to note that there are many advanced topics in harmony that couldn’t be included due to space limitations. These topics include chord progressions based on different scales, modal scales, hidden tonality, secondary dominants, chord substitutions, non-functional harmony, atonal music, modal interchange, borrowed chords, voice leading, 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 own 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.
