    Playing Extended Chords on Piano

    Extended chords are an essential part of piano playing, providing a rich and complex sound. However, playing extended chords can be challenging due to the number of notes involved. One way to manage this is by omitting certain notes, such as the root or the 5th, or by dividing the chord between both hands.

    Despite these techniques, extended chords can still create dense harmonies that require careful voicing. When inverted, these chords can produce complex clusters of notes that need to be approached with skill and precision. Mastering the voicing of extended chords takes time and practice, but it’s a crucial skill for any pianist looking to expand their repertoire.

    Chord Inversion on Piano

    Chord inversions are a foundational concept in music theory, helping to explain how chords are built and how they fit into progressions. However, when we talk about chord inversions on a piano keyboard, it’s important to keep in mind that the diagrams we use to show the notes in an inversion might not always match up with practical playing.

    In practice, pianists use different voicings and fingerings for chords, spreading the notes out across different octaves and positions on the keyboard. This means that the basic shape of a chord’s inversions as shown in diagrams might not always be the most efficient way to play the chord on a piano keyboard.

    So while chord inversion diagrams can help understand the sequence of notes in a chord, they don’t always give us the best way to play the chord on a piano. It’s up to each pianist to experiment with different voicings and find the most comfortable and efficient way to play the chord while still maintaining the intended harmonic function and sound.

     


    Music Theory and Harmony of E6/9

     

    Building the E6/9 Chord: Different Approaches

    Starting from the E Major Scale

    To create a 6/9 chord, you can use the Major scale as a reference by combining a Root, a 3rd, a 5th, a 6th, and a 9th.

    In this case, to build an E6/9 let’s start from the E Major scale:

     

    E Major Diatonic Scale up to 13th

    E Major Scale – Keyless Notation

     

    Apply the formula R, 3, 5, 6, 9 to get an E6/9 chord:

    1. Select the Root note, which is E.
    2. Pick the 3rd note, which is G#, and add it to the chord.
    3. Add the 5th note, which is B, and include it as well.
    4. Now, add the 6th which is C#.
    5. Lastly, include the 9th note of the E Major scale, which is an F#.

     


    by Combining Intervals

    To build a 6/9 chord, one approach is to combine specific intervals, namely a major 3rd, a minor 3rd, a major 2nd (whole-tone), and a major 3rd.

    3 + m3 + 2  + 3 = 6/9 Chords

    When constructing an E6/9 chord, you can see that

    • E-G# forms a major 3rd,
    • G#-B creates a minor 3rd,
    • B-C# makes a whole-tone interval, and
    • D-F# is a major 3rd.

    Stacking these intervals together creates an E6/9 chord.

     


    How to Use E 6/9 in a Chord Progression

     

    Since 6/9th chords are based on major triads with a sixth and a ninth added, they can substitute the major chords built on the scale of the root. This means that we can use the E6/9 chord in those positions on the scale where the harmonization makes a major chord.

    In some cases, a 6/9 chord can be used as a dominant chord, but it is less common than its use as a tonic or subdominant chord.

    The following tables illustrate the harmonization of scales that contain an E Maj7 or an E7 chord.

    on Major Scales

    Major Scales I ii iii IV V vi vii
    E E Maj7 ⇒ E6/9 F# min7 G# min7 A Maj7 B7 C# min7 D#m7b5
    B B Maj7 C# min7 D# min7 E Maj7 ⇒ E6/9 F#7 G# min7 A#m7b5
    A A Maj7 B min7 C# min7 D Maj7 E7 ⇒ E6/9 F# min7 G#m7b5
    • Tonic chord in E Major
    • Subdominant chord in B Major
    • Dominant chord in A Major (less common)

    F# F# min7 G#m7b5 A Maj7 B min7 C# min7 D Maj7 E7 ⇒ E6/9
    • Mediant chord in C# minor
    • Submediant chord in G# minor
    • Dominant chord in F# minor (less common)

     


    E6/9 Chord Function in Major and Minor Keys

    Understanding Scale Degrees

    When we harmonize a scale, we use the notes of the scale to create chords. This means that the notes of the chords are all found within the scale itself.

    Each note in the scale is assigned a degree, which represents its position in the scale. The degrees of the harmonized diatonic major scale are as follows:

    1. Tonic (1st degree): serves as the tonal center or home base of the music and provides a sense of resolution and stability.
    2. Supertonic (2nd degree): often serves as a passing tone or a bridge between the tonic and other scale degrees.
    3. Mediant (3rd degree): helps to define the overall tonality of the scale (major or minor) and lies midway between the tonic and the dominant.
    4. Subdominant (4th degree): often used as a contrasting or complementary harmony to the dominant.
    5. Dominant (5th degree): creates tension and a sense of expectation, which is resolved when returning to the tonic.
    6. Submediant (6th degree): lies midway between the tonic and the subdominant and often serves as a bridge between the dominant and the tonic.
    7. Leading tone (7th degree): one half step below the tonic and creates a strong sense of tension and desire to resolve to the tonic.

     


    E6/9 in E Major

    E6/9 can be used instead of an E Maj or E Maj7 chord, which is the first chord in the harmonized E 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.

    I ii iii IV V vi vii
    E Maj7 ⇒ E6/9 F# min7 G# min7 A Maj7 B7 C# min7 D#m7b5

    I V vi IV
    I V vi IV
    E6/9 B7 C# min7 A Maj7

     


    E6/9 in B Major

    The E6/9 chord can also be used as the fourth degree of the B major scale as a substitute for the E 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.

    I ii iii IV V vi vii
    B Maj7 C# min7 D# min7 E Maj7 ⇒ E6/9 F#7 G# min7 A#m7b5

     

    E6/9 as IV degree – Chord Progressions

    Try playing these chord progressions to get an idea of how E6/9 functions as a substitute for the subdominant (IV degree) in a chord progression.

     

    I IV V
    I IV V
    B Maj7 E6/9 | E Maj7 F#7

     

     I V vi IV
    I V vi IV

    I IV vi V
    I IV vi V
    B Maj7 E6/9 | E Maj7 G# min7 F#7

     


    E6/9 Chord in A Major

    Another (uncommon) way to use the E6/9 chord is as a substitution for the dominant chord in the A major scale. In this case, the E6/9 chord functions as a variation of the E7 chord, serving as the fifth degree of the A major scale.

    When used in a ii-V-I progression, the E6/9 chord on the fifth degree can function as the dominant chord that resolves to the first degree.

    I ii iii IV V vi vii
    A Maj7 B min7 C# min7 D Maj7 E7 ⇒ E6/9 F# min7 G#m7b5

     

    E6/9 as V degree – Chord Progressions

    I prefer resolving the E6/9 chord to an E7 chord within the same measure, but I encourage you to explore different options and experiment with other chord progressions to see what sounds best to you.

    ii V I
    ii V I
    B min7 E6/9 | E7 A Maj7

     

    I IV vi V
    I IV vi V

    I IV ii V iii vi ii V
    A Maj7 D Maj7 B min7 E6/9 | E7 C# min7 F# min7 B min7 E6/9 | E7

     


    E6/9 in C# minor

    Similarly, in the key of C# minor, the E6/9 chord can be used as a substitute for the E Maj7 chord as the third degree.

    i ii III iv v VI VII
    C# min7 D#m7b5 E Maj7 ⇒ E6/9 F# min7 G# min7 A Maj7 B7

     

    E6/9 as III degree – Chord Progressions

    These chord progressions show the E6/9 chord as a substitute for the mediant (III degree) chord.

     

    i III
    i III
    C# min7 E6/9 | E Maj7

     

    i III VII VI
    i III VII VI
    C# min7 E6/9 | E Maj7 B7 A Maj7

     

    Circle Progression
    i iv VII III VI ii V7 i
    C# min7 F# min7 B7 E6/9 | E Maj7 A Maj7 D#m7b5 G#7 C# min7

     


    E6/9 in G# minor

    Another instance where you can use an E6/9 chord instead of an E Maj7 is while playing in the key of G#. This is because the E Maj7 chord we are replacing is located on the sixth degree of the G-sharp minor scale.

    i ii III iv v VI VII
    G# min7 A#m7b5 B Maj7 C# min7 D# min7 E Maj7 ⇒ E6/9 F#7

     

    E6/9 as VI degree – Chord Progressions

    Try playing these chord progressions to get a sense of how an E6/9 chord can serve as an alternative to an E Maj7 chord when it functions as the submediant (VI degree) in a G# minor scale.

     

    i VI VII
    i VI VII
    G# min7 E6/9 | E Maj7 F#7

     

    i v VI VII
    i v VI VII

    Circle Progression
    i iv VII III VI ii V7 i
    G# min7 C# min7 F#7 B Maj7 E6/9 | E Maj7 A#m7b5 D#7 G# min7

     


    E6/9 in F# minor

    Using an E6/9 instead of a Major or Major 7th as the dominant chord is not so common but it is worth mentioning.

    i ii III iv v VI VII
    F# min7 G#m7b5 A Maj7 B min7 C# min7 D Maj7 E7 ⇒ E6/9

     

    E6/9 as VII degree – Chord Progressions

    You can try playing these chord progressions to hear how the E6/9 chord works as a substitute for the subdominant (IV degree) or you can play it with the dominant 7th chord:

     

    i VI VII
    i V VII
    F# min7 D Maj7 E6/9 | E7

     

    i v VI VII

    Conclusion

    The chord progressions and examples presented in this post provide a comprehensive overview of the most common uses of the E6/9 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.
