    Playing Extended Chords on Piano

    Extended chords are commonly used in piano playing, but they can be tricky to play in their entirety due to the large number of notes involved. To make these chords more manageable, pianists often omit certain notes, such as the root or the 5th. Another technique is to split the chord between both hands, playing either full or partial chords in each hand.

    How to play a B11

    For example, to play the B11 chord, you can start by playing the root note B with your left hand. Then, with your right hand, you can play the major 3rd D#, minor 7th A, and the 11th note E. This will result in a simplified B11 chord that consists of the root note, major 3rd, minor 7th, and the 11th notes only.

    B + D#, A, E

    However, even when notes are omitted or split between hands, extended chords can still create complex and dense harmonies. When these chords are inverted, the resulting clusters of notes can be particularly challenging to voice effectively.

     

    B11 Chord Inversions

     

    The B11 chord has a total of 5 inversions:

    Chord Inversions on Piano

    Understanding chord inversions is an essential aspect of music theory as it helps to explain how chords are constructed and used in progressions. When playing chord inversions on a piano, it’s important to keep in mind that the diagrams used to illustrate the order of notes may not always be practical to play.

    To achieve the proper chord voicings on a piano, you need to distribute the notes of the chord across various octaves and positions on the keyboard. This often means that the basic shape of the chord’s inversions shown in diagrams may not be the most convenient or comfortable way to play the chord.

    While chord inversion diagrams can be useful in comprehending the structure and sequence of notes in a chord, it’s recommended 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 B11

     

    The B11 chord is an extension of the B7 chord and is commonly used on the V and VII degree of major and natural minor scales, respectively. It can be used in all the positions where B7 can be played, but a more common use is to play it in conjunction with a B7 chord. However, it’s important to note that some positions may not work as well as others when using B11 instead of B7.

    If you want to experiment with using B11 as an alternative to B7, you can start by checking out the B7 chord page for ideas on where to begin. Trying out the B11 chord in different positions can help you understand which ones work well and which ones may not be as effective.

     


    Building the B11 Chord: Different Approaches

    Starting from the B Major Scale

    To form an 11th chord, you combine the root, the major 3rd, the 5th, the minor 7th, the major 9th and the 11th from a major scale:

     

    B Major Diatonic Scale up to 13th

    B Major Scale

     

    B Major Diatonic Scale up to 13th - Keyless Notation

    B Major Scale- Keyless Notation

     

    To create a B11 chord, apply the formula R, 3, 5, m7, 9, 11 in the following manner:

    1. Begin with the Root note, B.
    2. Select the major 3rd interval, D#.
    3. Add the 5th interval, which is F#.
    4. Add the minor 7th interval, A.
    5. Add the major 9th, which is a 2nd at the higher octave, C#.
    6. Lastly, add the 11th E, which is a 4th interval at the higher octave.

    By following this simple formula, you can create a dominant 11th chord from any major scale.

     


    by Combining Intervals

    One method to create a dominant 11th chord is by combining specific intervals – a major 3rd, a minor 3rd, a minor 3rd, a major 3rd, and a minor 3rd. This is the formula:

    3 + m3 + m3 + 3 + m3 = 11th Chords

    To build a B11 chord,

    • we begin with the root note B and
    • add a major 3rd interval, which is four half-steps up from B, to get D#.
    • Next, we add a minor 3rd interval, which is three half-steps up from D#, to get F#.
    • Continuing in this pattern, we add another minor 3rd interval to get A and
    • then a major 3rd interval to get C#.
    • Finally, we add the 11th note (E), which is a minor 3rd higher than C# to complete the chord.

     


    by Combining Chords

    An alternative way to build dominant 11th chords is to merge a major triad with the major chord based on its minor 7th.

    To form a B11 chord, for instance, you can blend a B Major triad (B, D#, F#) with an A Major chord (A, C#, E).

    B Major + A Major = B11

    When played together, these two chords produce a B11 chord.

     


    How to Use B11 in a Chord Progression

     

    The B11 chord is essentially an extension of the B7 chord, with the addition of the 9th (C#) and the 11th (E) notes. As the B11 chord includes the dominant 7th note (A), it serves a similar function to the B7 chord in creating tension and leading to the tonic chord.

    Because of this, the B11 chord can often be substituted for the B7 chord and vice versa, depending on the desired musical effect. While there are examples of 11th chords used as tonic chords, this post will focus on the more common uses of the B11 chord.

    Here are the tables of the major and natural minor scales that include the B dominant 7th chord, which can be substituted or complemented by a B11 chord:

    B11 Chord Function in Major and Minor Keys

    Understanding Scale Degrees

    When we form chords from a scale, each note in the scale is given a specific degree that reflects its position within the scale. The degree of a note in a scale determines its function and the role it plays in the overall harmony of the music.

    1. Starting with the first degree of the scale, we have the Tonic chord. This chord serves as the foundation of the scale, providing a stable tonal center for the music. It’s like the “home base” of the music, and all melodies and harmonies are anchored to this chord.
    2. Moving on to the second degree, we have the Supertonic. This degree acts as a transitional note between the tonic and other notes in the scale, creating a sense of movement and flow in the melody or harmony.
    3. The third degree is the Mediant, which is located halfway between the tonic and dominant notes. This degree helps to establish whether the scale is major or minor and plays a critical role in determining the mood and emotional impact of the music.
    4. The fourth degree is the Subdominant, which complements the dominant and adds tension and resolution to the music. It creates a push-pull effect that keeps the listener engaged and interested.
    5. The fifth degree is the Dominant, which generates tension and a sense of expectation. It often acts as the climax of a musical phrase or section and is resolved by returning to the tonic.
    6. The sixth degree is the Submediant, which provides a sense of stability and restfulness to the music. It’s often used as a transition between the dominant and tonic, creating a feeling of calm and relaxation.
    7. Finally, we have the seventh degree, the Leading tone. This degree 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 completion in the melody or harmony.

    Understanding the scale degrees is essential for creating chords and understanding how they relate harmonically to one another. By knowing the function of each degree, we can create more interesting and effective harmonies in our music.

     


    B11 as Dominant Chord in E Major

    In the context of the E major scale, the B11 chord can serve as the dominant chord on the fifth degree. This means that B11 would be the fifth chord in the scale and have a strong tendency to resolve to the tonic chord, which is E major in this case, or to the VI chord (C# min7), which is the relative minor chord of E major.

    Chord Similarities

    Dominant 11th and 9sus4 Chords

    The dominant 11th and 9sus4 chords share many similarities, as they both consist of similar sets of notes. The only difference between them is that the 9sus4 chord omits the 3rd note, while the dominant 11th chord includes the 4th note played at a higher octave. The dominant 11th chord is composed of the root, 3rd, 5th, 7th, 9th, and 11th notes, while the 9sus4 chord includes the root, 4th, 5th, 7th, and 9th notes.

    For instance, a B dominant 11th chord includes the notes B, D#, F#, A, C#, and E, while a B 9sus4 chord is composed of B, E, F#, A, and C#.

    The presence of the major 3rd note in the dominant 11th chord contributes to its stability, resulting in a less tense sound.

    On the other hand, the absence of the 3rd note in the 9sus4 chord creates a more suspended and unresolved sound. Nevertheless, both chords have a similar sound due to the inclusion of the 4th (or 11th) interval.

    Dominant 11th and add11 Chords

    The dominant 11th and add11 chords share many similarities in terms of their notes. Both chords contain the Root, 3rd, 5th, and 11th notes, with the only difference being the presence of the 7th and 9th notes in the dominant 11th chord.

    For example, the B11 is made by B, D#, F#, A, C#, and E while the B add11 is made by B, D#, F#, E.

    The add11 chord is generally considered to be a lighter chord due to the absence of the 7th and 9th notes, which provide tension and richness to the dominant 11th chord. However, the presence of the 11th note in both chords creates a similar sound, making them sound alike.
