In the exploration of upper scale extensions for enriching chord progressions, we’ll consider the evolution and application of chords that transcend the conventional triad structure by incorporating notes beyond the seventh–notably, the ninth, eleventh, and thirteenth.

The thirteenth chord represents the zenith of diatonic extension, encapsulating all seven tonal degrees. Historical perspectives reveal that while extended chords saw sparse use in the Baroque period, their prevalence escalated through the Classical and into the Romantic era, predominantly within dominant functions.

This discourse extends into the twentieth century and beyond, where in genres like jazz, jazz fusion, and funk, such chords are pivotal, often highlighted with added and altered notes for enhanced sonic texture and color. You will explore the nuanced roles these extensions play, from their foundational theoretical underpinnings in the works of eighteenth-century theorists to their expressive deployment in modern music, underlining the dynamic interplay between classical functional harmony and the pursuit of novel harmonic landscapes in contemporary compositions.

Understanding Extended Chords

Definition and basic types of extended chords

Extended chords are harmonies that include notes added beyond the traditional triad and seventh chords, encapsulating ninth, eleventh, and thirteenth chords. These chords introduce a fuller sound and are crucial for adding colour and complexity to music.

The ninth chord includes the root, third, fifth, seventh, and ninth. The eleventh chord adds an eleventh note on top of these, and the thirteenth chord, the farthest extension diatonically possible, includes all seven tonal degrees.

The historical evolution of extended chords

Extended chords were sparingly used in the Baroque era and began to appear more frequently during the Classical period. Their significant utilization was witnessed during the Romantic era, often fulfilling a dominant function. In the 20th century, these chords became fundamental in jazz, jazz fusion, and funk, reflecting a shift from functional to colouristic and textural roles in music.

The role of extended chords in modern music genres

In contemporary music genres, extended chords play a pivotal role in defining the sound and stylistic characteristics. They are especially prominent in jazz and jazz fusion, where they serve not just harmonic functions but also add richness and texture. In popular music genres, extended chords provide a means to escape the predictability of triads and seventh chords, contributing to a more sophisticated sonic palette.

The Components of Extended Chords

Breaking down the ninth, eleventh, and thirteenth chords

The ninth, eleventh, and thirteenth chords build upon the seventh chord by sequentially adding the ninth, eleventh, and thirteenth scale degrees, respectively. These chords offer a rich harmonic layering that can significantly enhance musical texture.

Commonly omitted notes and why

Not all notes in an extended chord are consistently voiced, with the fifth and any notes between the seventh and the highest note often omitted unless they are altered. These omissions are typically made to avoid harmonic clutter and to ensure clarity of the chord’s essential colour and function. In jazz contexts, the root and fifth are sometimes left to the bass instruments, focusing on the chord’s more characteristic tones.

Altered extensions and their impact on chord color

Altered extensions, such as a flat ninth or sharp eleventh, further increase the harmonic complexity and introduce a unique sonority to the music. These alterations impact the chord color significantly, creating tensions that are resolved or left hanging for expressive purposes.

Voice Leading in Extended Chords

Traditional rules during the common practice period

During the common practice period, voice leading rules for extended chords emphasized smooth, stepwise movement between the chord tones. Resolving the third of a chord upward to the tonic and the seventh downward was particularly stressed to maintain harmonic cohesion.

Modern approaches to voice leading with extended chords

Modern voice leading practices with extended chords have become more flexible, reflecting the evolution of musical styles. In jazz and contemporary music, voice leading often prioritizes the maintenance of chord color and texture over traditional resolution rules, allowing for more creative freedom.

Examples of effective voice leading in various music genres

Effective voice leading in music genres such as classical, jazz, and pop showcases the versatility of extended chords. In jazz, for example, innovative voice leading techniques contribute to the genre’s characteristic sound, enabling smooth transitions between complex harmonic structures.

Functional Harmony and Extended Chords

Dominant and secondary dominant functions

Extended chords often fulfill dominant or secondary dominant functions in functional harmony, with the inclusion of the seventh and higher extensions adding tension that seeks resolution. This characteristic makes them particularly effective in leading to the tonic or other target chords.

The concept of supposition and its application

Supposition, or the theoretical placement of a hypothetical bass note below the fundamental bass to consider ninth and eleventh chords as extensions of seventh chords, played a key role in 18th-century harmonic theory. This concept helped in the understanding and classification of extended chords within traditional harmony.

Circle progression resolutions with extended chords

Circle progressions, moving in fifths from one chord to the next, utilize extended chords for added harmonic interest and tension. The resolutions in these progressions often feature extended chords moving to resolve on a tonic or other stable chord, demonstrating their functional utility.

Extended Chords in Jazz and Fusion

The quintessential role of extended chords in jazz

Extended chords are fundamental in jazz, where they contribute to the genre’s characteristic harmonic richness and texture. They provide a basis for improvisation, offering a wide range of expressive possibilities.

Voicings for jazz piano and guitar

Voicings, or the specific arrangements of chord tones, for jazz piano and guitar often emphasize the chord’s color tones—such as the third, seventh, and any altered or added tones—over the foundational root and fifth, which might be implied or played by other instruments in the ensemble.

Innovative uses of extended chords by jazz legends

Jazz legends like Bill Evans and Wes Montgomery innovated in their use of extended chords, employing them not only for harmonic richness but also as a vehicle for melodic and thematic development within their compositions and improvisations.

Richer Chord Progressions with Extended Chords

Integrating extended chords into standard progressions

By integrating extended chords into standard chord progressions, composers and arrangers can inject a fresh sense of depth and complexity, transforming otherwise predictable progressions into captivating harmonic landscapes.

Creating tension and resolution with extended chords

Extended chords excel in creating tension due to their additional dissonances, which seek resolution. Creative use of these tensions and resolutions can significantly enrich a music piece’s emotional and expressive range.

Examples of progressions that effectively use extended chords

Progressions in genres ranging from classical to contemporary pop demonstrate the effective use of extended chords. These progressions often feature unexpected turns and a rich harmonic tapestry, highlighting the chords’ ability to add texture and complexity.

Extended Chords in Composition and Songwriting

Adding color and texture to melodies with extended chords

Extended chords offer composers and songwriters a powerful tool to add color and texture underneath melodies. By carefully selecting the chords’ extensions and alterations, a melody can be enhanced or contrasted in compelling ways.

The role of extended chords in thematic development

In thematic development, extended chords can provide harmonic variety and contrast, helping to differentiate sections and develop musical ideas. Their rich harmonic palette supports complex emotional narratives and thematic evolution.
