In music, the dominant 79 chord[1] ("dominant seven sharp nine" or "dominant seven sharp ninth") is a chord built by combining a dominant seventh with an augmented second. This chord is used in many forms of contemporary popular music, including jazz, funk, R&B, hip hop,[citation needed] rock and pop. As a dominant chord in diatonic harmony, it most commonly functions as a turnaround chord, returning to the tonic. However, the 7#9 is also frequently used in some styles as a tonic without the resolution typical of a dominant chord.[citation needed]

Name[edit]

The chord is also sometimes colloquially known, among pop and rock guitarists, as the Hendrix chord or Purple Haze chord, nicknamed for guitarist Jimi Hendrix,[2][3] who showed a preference for the chord and did a great deal to popularize its use in mainstream rock music.[4] When used by the Beatles it has also been called the Gretty chord although this can refer to a distinct 6 string version.[5][6]

Spelling and notation[edit]

There are two main ways to spell the chord, depending on the musical style, kind of musical notation (score or chord symbols), and personal taste. One consists of a dominant seventh chord with an added minor third, placed one or more octaves over the major third;[7][8] the other consists of a dominant seventh chord with an added augmented ninth.[9] Only the second type of notation can be represented using the common chord symbol notation systems.

Sometimes, in publications which include both scores and chord symbols, the score is notated with a both natural and flattened third, while the chord symbol has the sharpened ninth.[7][8]

Other more uncommon notations and names include major/minor or 7 (add min 3).[10]

Kenn Stephenson says that in rock music the sharp ninth spelling is much more prevalent than the split third version.[11]

Nature of the chord[edit]

The 79 is an altered chord, and it is one option when seeing the chord symbol 7alt. It is functionally a dominant chord, and thus "wants" to resolve to the tonic in diatonic harmony.

Stuart Isacoff has called the chord "funky" or "bluesy", because of the tension "generated between the major third and the augmented ninth";[1] while Doug Munro deems it as "jazzy"[12] rather than bluesy. Eric Starr says that "the sharp nine tends to be edgier, bluesier, and meaner sounding [than the flat nine]."[13] In jazz, 79 chords, along with 79 chords, are often employed as the dominant chord in a minor ii-V-I turnaround. For example, a ii V I in Cm could be played as: Dm75 - G79 - Cm7.

The 79 represents a major divergence in the world of tertian chord theory. That simplistic Constructionist definition of chords being stacks of major and minor thirds does not satisfy the 79, as the interval between the minor seventh and augmented ninth is that of an augmented third. Similar pertains to the rarer M79, where the interval between the major seventh and minor ninth is that of a diminished third. Rather than allow the inclusion of diminished and augmented thirds into the theory fully, a typical solution in jazz is to define chords as stacks of chordal degrees, where each degree has some range of selection from which to take its note or notes.[14] Thus, for example, the ninth is available in flat, natural, sharp, and flat-and-sharp "alt" styles.

History[edit]

Classical[edit]

The English cadence is a distinctive contrapuntal pattern particular to the authentic or perfect cadence described as archaic[15] or old-fashioned[16] sounding. This pattern was primarily used by English composers of the High Renaissance and Restoration periods. The hallmark of this device is the dissonant augmented octave (compound augmented unison) produced by a false relation between the split seventh scale degree.

The English cadence is a type of full close featuring the blue seventh against the dominant chord[17] which in C would be B and G-B-D.

Measures 1-3 and 41-42 of Debussy's Feuilles Mortes, from his second book of Préludes (1913).

The dominant 79 chord appears in impressionist classical music. An example can be heard in Claude Debussy's Feuilles Mortes, from his second book of Préludes (1913). There, the unresolved, dissonant ninth chords (at least a, "C7with a "split third" and "added minor ninth"[18]) help create, according to Richard Bass, an "utterly sad, desolate character," throughout the piece.[19]

This chord can also be found in serial music. For example, the Elektronische Musik vom Freitag aus Licht (1991–94) by Karlheinz Stockhausen, from an opera composed using formula technique, concludes on this chord.[20]

Jazz and blues[edit]

A usual clash between a flattened seventh degree (blue note) and a dominant seventh chord in a blues phrase. Note how G is enharmonically equivalent to Fdouble sharp (the augmented ninth of E).[10]

The dominant 79 chord is normally found in blues contexts, because in a blues scale a minor third in the melody is usually played against a dominant seventh chord.[10]

The chord was used in popular music as far back as the bebop era of the 1940s, and, in instances, it appears with some regularity in blues and rhythm-and-blues of the 1950s and 1960s.

Rock/pop[edit]

Hendrix chord[edit]

While this sonority has been previously used in jazz and related styles, one particular voicing of this chord is commonly nicknamed the "Hendrix Chord" among rock guitarists. This association is because it was a favorite of Jimi Hendrix, who did a great deal to popularize its use in mainstream rock music.[4]

The earliest recorded evidence of his use of the chord is on the Isley Brothers' "Testify, Parts 1 and 2" (1964),[citation needed] one of his few recordings before the start of his solo career in 1966. The most notable Hendrix song that features the 79 chord is "Purple Haze", while it is also implied in "Foxy Lady",[22][23] both coming from his 1967 album Are You Experienced?. When performing "Voodoo Child (Slight Return)" live Hendrix later used not only E79, the sharpened ninth chord on the tonic, but also D79 and C79 chords, the subtonic and submediant.[23]

This harmonic device is one of many factors that, according to Gleebeek and Spairo, contribute to "the dirty, raw, metallic, angular sounds of [...] Hendrix songs".[3] It is an example of how he would embellish chords "to add new colours to the music, often derived from his own roots in black music".[3] "In essence," John Perry[disambiguation needed] writes, the Hendrix chord is "the whole of the blues scale condensed into a single chord."[23]

Other musicians[edit]

The chord was used by the Beatles in songs such as "The Word" and "Taxman".[24] McCartney called this a "great ham-fisted jazz chord" that was taught to them by Jim Gretty who worked at Hessey's music shop in Whitechapel, central Liverpool. George Harrison uses it as the penultimate chord of his solo on "Till There Was You".[5]

The chord (a D7#9) can also be heard in Pink Floyd's Shine On You Crazy Diamond,[citation needed] notably just before, and at the end of, the final guitar solo before the vocals first come in.

The chord is favored by Pixies lead guitarist Joey Santiago, with D79, reminiscent of the opening to "A Hard Day's Night", opening and being called the "secret ingredient," to the song "Here Comes Your Man" and "brutally scraped" F79 featured on the chorus to "Tame" against the three chord rhythm guitar part's D, C, and F chords.[25]

Use as a primary or tonic chord in funk and disco music of the 1970s includes Heatwave's "Boogie Nights".[11]

Notes[edit]

  1. ^ A just major third (5/4), perfect fifth (3/2), minor seventh (9/5), and augmented second (75/64). Many other just tunings are possible, with higher limits allowing overtone tunings using smaller whole-number ratios, such as 10:12:14:19 or 20:24:28:37.
