     How to play an Eb9sus4

    You can start by playing the root note Eb with your left hand. Then, with your right hand, you can play the 4th Ab, the minor 7th Db, and the 9th note F. You can add the 5th, Bb, to get a little bit of dissonance.

    Eb + (Ab, Db, F)

    This will result in a simplified Eb9sus4 chord that consists of the root note, perfect 4th, minor 7th, and the 9th notes only.

    Another simple way to voice this chord is to play the root note with your left hand and a Bb min7 chord with your right hand.

    Eb + Bbm7 =

    Eb + (Bb, Db, F, Ab) =

    Eb9sus4

    This voicing is essentially the second inversion of a 9sus4 chord without the root note, which is equivalent in sound to a minor 7th chord built on the 5th note from the root.

    Chord Inversions on Piano

    While chord inversions are a fundamental concept in music theory, the diagrams that show the sequence of notes in a complex chord on a piano keyboard may not necessarily be practical for playing. This is because proper chord voicings involve distributing the notes of the chord across different octaves and positions on the keyboard. This can be very different from the basic shape of the chord’s inversions. Therefore, the diagrams of chord inversions are mainly intended to show the sequence of notes on the piano keyboard for music theory purposes, rather than for practical playing.


    Music Theory and Harmony of Eb9sus4

    What are Suspended  Chords?

    Suspended chords are a type of chord where the third note is replaced by either a major second or a perfect fourth. This creates sus2 and sus4 chords, which have a unique and sometimes unresolved sound that adds tension and interest to music. These chords can be used as substitutes for major and minor chords because of their neutral nature.

    The 9sus4 chord is a more intricate version of the sus4 chord, featuring a minor 7th and 9th note in addition to the perfect fourth. This chord is commonly used in jazz and blues music to add complexity and interest to chord progressions. It is often used as a substitute for dominant 7th chords.

    Building the Eb9sus4 Chord: Different Approaches

    Starting from a Major Scale

    To create a 9sus4 chord, you can use the Major scale as a reference by combining a Root, a 4th, a 5th, a minor 7th, and a 9th.

    In this case, to build an Eb9sus4 let’s start from the Eb Major scale, which includes the notes Eb, F, G, Ab, Bb, C, and D.

    Apply the formula R, 4°, 5°, m7°, 9° to get an Eb9sus4 chord.

    1. Select the Root note, Eb.
    2. Pick the 4th note, Ab.
    3. Add the 5th note, which is Bb.
    4. To add the 7th note, we need to use a minor 7th interval, which means we must use a flat seventh. In the Eb Major scale, the 7th note is D, so the minor 7th is Db.
    5. Lastly, include the 9th note of the Eb Major scale, which is F.

     


    by Combining Intervals

    To build a 9sus4 chord, you can stack together a perfect 4th, a whole-tone (or major 2nd), a minor 3rd, and a major 3rd.

    4 + 2 + m3 + 3 = 9sus4 Chords

    In fact, when building an Eb9sus4 chord, you can see that Eb-Ab is a perfect 4th, Ab-Bb is a major 2nd, Bb-Db is a minor 3rd, and Db-F is a major 3rd.

     


    How to Use Eb9sus4 in a Chord Progression

     

    Suspended chords have a unique quality that sets them apart from major and minor chords. They are neither major nor minor, which makes them a useful tool for creating tension and suspense in a musical composition before resolving to a stable major or minor chord.

    To use an Eb9sus4 chord in a chord progression, you can refer to the following tables, which show the most common positions where the chord can be found or used. However, it’s important to note that, since this chord features a minor 7th, it cannot be used with Maj7 chords, such as sus2 or sus4 chords. Nonetheless, it can be used on dominant chords and in all positions where an Eb min7 is present.

    Eb9sus4 as Substitute of Eb7

    Eb9sus4 can be used as a substitute for Eb7 in major and minor keys. In Ab major, Eb7 can be replaced with Eb9sus4 in the V position. Similarly, in the F minor key, Eb7 can be substituted with Eb9sus4 in the VII position.

    Eb9sus4 as Substitute of Eb min7

    Eb9sus4 chord can be used as a substitute for Eb minor chords in various major and minor keys. Note that in Cb (B) Major and Ab minor, F can clash with the E notes that are part of those keys. While this doesn’t prevent you from using the Eb9sus4 chord in those positions, it’s important to be aware that it can create a strong dissonance with the melody or other elements of the composition.

    Eb9sus4 Chord Function in Major and Minor Keys

    Understanding Scale Degrees

    When creating chords from a scale, each note in the scale is assigned a degree, which reflects its position in the scale. In the diatonic major scale, there are seven degrees, and each degree has a unique role in the overall harmony of the scale.

    1. The first degree of the scale is called the Tonic, and it serves as the foundation for the scale. It provides a stable tonal center and is often referred to as the “home base” of the music.
    2. The second degree of the scale is called the Supertonic. It’s typically used as a passing note between the tonic and other scale degrees, and it adds a sense of movement to the melody or harmony.
    3. The third degree of the scale is called the Mediant. It’s located halfway between the tonic and dominant notes and helps to establish whether the scale is major or minor.
    4. The fourth degree of the scale is called the Subdominant. It’s often used as a complementary harmony to the dominant and adds a sense of tension and resolution to the music.
    5. The fifth degree of the scale is called the Dominant. It generates tension and a sense of expectation, and it’s typically resolved by returning to the tonic.
    6. The sixth degree of the scale is called the Submediant. It’s often utilized as a transition between the dominant and tonic, and it provides a sense of stability and restfulness to the music.
    7. The seventh degree of the scale is called the Leading tone. It’s located one half step below the tonic and produces a strong sense of tension and a desire to resolve to the tonic. It’s often used to create a sense of resolution and finality in the melody or harmony.

     


    Eb9sus4 in Ab Major

    When playing in the key of Ab Major, the fifth degree of the scale is Eb7. However, substituting it with an Eb9sus4 chord can introduce a feeling of anticipation and suspense, which can be resolved by returning to the dominant chord or by moving to another degree of the scale.

    Ab Maj7 Bb min7 C min7 Db Maj7 Eb7 F min7 Gm7b5

    You can experiment with different ways of playing the Eb9sus4 chord in the key of Ab Major. For example, you could play just the Eb9sus4 chord, or split the measure in half and play both the Eb9sus4 and Eb7 chords. Another option is to invert the order of the chords, playing the Eb7 chord first and then resolving to the Eb9sus4 chord.

    Eb9sus4 in F Minor

    In F minor, the seventh degree of the scale features an Eb7 chord. By incorporating an Eb9sus4 chord in this position, you can generate a feeling of expectation and tension, which prepares the listener for the eventual resolution to the tonic chord. You can experiment with playing just the Eb9sus4 chord or combining it with the Eb7 chord.

    Eb9sus4 in Ab Minor (Non Diatonic)

    In the key of Ab minor, you can use the Eb9sus4 chord as an alternative or substitution for the v degree chord (Eb minor). However, it’s important to note that the Eb9sus4 chord contains an F, which is not diatonic to the Ab minor scale that includes a natural E. As a result, it’s generally recommended to avoid using the Eb9sus4 chord in this context, but it’s worth experimenting to see if it suits your desired sound.

    9sus4 and 11th Chords: Similarities and Differences

    9sus4 chords share almost the same notes as 11th chords. The only difference is the presence of the 3rd in 11th chords.

    Eb9sus4 = Eb, Ab, Bb, Db, F

    Eb11 = Eb, G, Bb, Db, F, Ab

    However, it is important to note that a 4th is not the same as an 11th, even if they are the same note. There is an octave of difference between them. This distinction may not matter when playing an inversion of the chord, but it is still important to be aware of.
