Navigating the realm of extended chords can sometimes feel overwhelming. Take the 11th chord, as a notable example; it frequently enough gets lost in the shuffle of various chord-naming systems, creating a unique niche all its own.
extended chords expand upon the fundamental major or minor triad by incorporating additional tones such as the 7th (or b7th), 9th, 11th, and even the 13th. Music theory typically presents these additions in a straightforward ascending order, resulting in increasingly intricate and beautiful chords.
Though, as we venture into the territory of 11th and 13th chords, the harmonic structure can become quite ‘thick,’ leading to the frequent omission of the 3rd and 5th notes for practicality.
Considering the physical limitations of playing multiple notes on the guitar together (not to mention in scale order), it becomes essential to determine which notes can be left out while still adhering to the theoretical framework of these chords. Let’s explore some examples to clarify this concept!
Example 1: G11 Chord
The G11 chord serves as a practical illustration of how these chords are structured. In theory, a G11 chord comprises the notes Root-3rd-5-b7-9-11, or G-B-D-F-A-C in the key of G. This arrangement effectively includes all necessary notes in ascending order: Root (G), b7th (F), 9th (A), and 11th (C). The F on the first string acts as a duplicate b7, and for harmonic simplicity, the 3rd (B) is often excluded. This chord is sometimes referred to as F/G.
Example 2: C11 Chord
The C11 chord exemplifies the process of simplifying an extended chord for clarity and practicality. Rather of the full six-note structure of Root-3rd-5th-b7th-9th-11th (C-E-G-Bb-D-F), we streamline it to Root-11th-b7th-9th (C-F-Bb-D) in ascending order. The 3rd (E) and 5th (G) are omitted, even though the 5th can be added on the first string if desired, known as Bb/C.
Example 3: Cmaj11 Chord
While we’ve primarily focused on building 11th chords using the dominant or b7th, we can also construct them with a major 7th. For instance, the C11 chord from the previous example can be transformed into a Cmaj11 by raising the b7th (Bb) to a B natural. This major 7th is what gives the chord its ‘maj’ designation.
Example 4: Dm11 chord
In this example, we explore the Dm11 chord, which can also be constructed from a minor triad. The theoretical structure of a min11 chord consists of Root-b3rd-5th-b7th-9th-11th (D-F-A-C-E-G).The chord diagram shows that we have all necessary notes except for the 5th (A), and they are arranged in scale order!
Example 5: Dm/maj11 Chord
In the previous example, we constructed a maj11 chord based on a major triad. By raising the b7th in our Dm11 from the last example, we create a Dm/maj11 chord, which adds a dramatic flair to the sound. This chord presents a unique challenge for both the fingers and the mind, illustrating the complexity behind some of the more enigmatic chord-naming conventions!
