from Wikipedia

The double harmonic major scale[1] is a musical scale with a flattened second and sixth degree. This scale is enharmonic to the Mayamalavagowla raga, Bhairav raga, Byzantine scale, Arabic scale (Hijaz Kar),[1][2] and Gypsy major scale.[3] It can be likened to a gypsy scale because of the diminished step between the 1st and 2nd degrees. Arabic scale may also refer to any Arabic mode, the simplest of which, however, to Westerners, resembles the double harmonic major scale.[4]

[edit]

The sequence of steps comprising the double harmonic scale is :

half, augmented second, half, whole, half, augmented second, half

Or, in relation to the tonic note

minor second, major third, perfect fourth and fifth, minor sixth, major seventh, octave

However, this scale is commonly represented with the first and last half step each being represented with quarter tones:[citation needed]

The non-quarter tone form is identical, in terms of notes, to the North Indian Thaat named Bhairav and the South Indian (Carnatic) Melakarta named Mayamalavagowla.

The double harmonic scale is arrived at by either:

It is referred to as the "double harmonic" scale because it contains two harmonic tetrads featuring augmented seconds. By contrast, both the harmonic major and harmonic minor scales contain only one augmented second, located between their sixth and seventh degrees.

There is a variation of the double harmonic major scale called Double Harmonic Majorb7, which is also the fifth mode of the harmonic minor scale. This variation is sometimes confused with the double harmonic major scale because many sources refer to it simply as "double harmonic major" without indicating the "b7" sign. The primary difference between these two scales is the seventh degree, with the double harmonic majorb7 scale having a flat seventh (♭7) and the Double Harmonic Major having a natural seventh (7).

The scale contains a built-in tritone substitution, a dominant seventh chord a half step above the root, with strong harmonic movement towards the tonic chord.

The double harmonic scale is not commonly used in classical music from Western culture, as it does not closely follow any of the basic musical modes, nor is it easily derived from them. It also does not easily fit into common Western chord progressions such as the authentic cadence. This is because it is mostly used as a modal scale, not intended for much movement through chord progressions.

The double harmonic major scale (in the key of E) was used in Nikolas Roubanis's "Misirlou", and in the Bacchanale from the opera Samson and Delilah by Saint-Saëns. Claude Debussy used the scale in "Soirée dans Grenade", "La Puerta del Vino", and "Sérénade interrompue" to evoke Spanish flamenco music or Moorish heritage.[5] In popular music, Ritchie Blackmore of Deep Purple and Rainbow used the scale in pieces such as "Gates of Babylon" and "Stargazer". The Miles Davis jazz standard "Nardis" also makes use of the double harmonic.[citation needed]. Opeth used this scale in their song "Bleak" from the album Blackwater Park. It is also used by Hans Zimmer in his score for Dune.

Symmetry and balance

[edit]

The double harmonic scale features radial symmetry, or symmetry around its root, or center note. Breaking up the three note chromaticism and removing this symmetry by sharpening the 2nd or flattening the 7th note respectively by one semitone yields the harmonic major and Phrygian Dominant mode of the harmonic minor scales respectively, each of which, unlike the double harmonic minor scale, has a full diminished chord backbone.

Because it features symmetry, its steps form a palindrome. Using the letters T = tone, S = semitone and M = minor third, we can give the seven steps of the scale as SMSTSMS. This string of letters reads the same backwards. In comparison, among the modes of the major scale, the Dorian mode is a palindrome.

Whenever a scale is a palindrome, or has a mode which is palindromic, reflections of that scale generate modes of that same scale (usually chromatically transposed to another root). Thus any reflection of double harmonic gives rise to a class of pitches which contain a double harmonic scale, just like (thanks to the palindromic Dorian) any reflection of the major scale around any point gives rise to a class of pitches which contain the major scale. However, the major scale itself (Ionian mode), in contrast to the double harmonic major, is not a palindrome; its reflection around its root gives rise to a Phrygian mode. The double harmonic major is its own reflection around the root, itself being the palindromic mode.

The double harmonic scale (and its modes like the Hungarian minor scale) is the only seven-note scale (in 12-tone equal temperament) that is perfectly balanced; this means that when its pitches are represented as points on a circle (whose full circumference represents an octave), their average position (or "centre of mass") is the centre of the circle.[6]

Modes

[edit]

Like all heptatonic (seven-pitch) scales, the double harmonic scale has a mode for each of its individual scale degrees. The most commonly known of these modes is the 4th mode, the Hungarian minor scale, most similar to the harmonic minor scale with a raised 4th degree. The modes are as follows:[7]

Mode Name of scale Degrees
1 Double harmonic major 1 2 3 4 5 6 7 8
2 Lydian 2 6 1 2 3 4 5 6 7 8
3 Ultraphrygian 1 2 3 4 5 6 double flat7 8

[edit]

Some of the closest existing scales to the double harmonic major scale are the Phrygian dominant scale, the fifth mode of the harmonic minor scale, as they are alike save for the Phrygian dominant's flattened seventh degree. The harmonic major scale (also known as major flat 6 and Ionian flat 6) is identical to the standard major scale aside from the sixth scale degree being flattened by a semitone, differing from the double harmonic major in having a natural second degree.

The double harmonic scale, also known as the double harmonic major scale, is a heptatonic musical scale defined by the interval pattern of a half step, augmented second, half step, whole step, half step, augmented second, and half step. This structure produces the notes C, D♭, E, F, G, A♭, B when rooted on C, featuring a flattened second and sixth degree relative to the , which imparts a distinctive exotic and tense character due to the two augmented seconds. The scale exhibits radial symmetry, making it unique among seven-note scales in twelve-tone , and it serves as the parent scale for several modes, including the Byzantine and Hungarian minor. Originating in Middle Eastern musical traditions, the double harmonic scale is closely associated with the Hijaz Kar mode and Persian influences, where its augmented seconds evoke emotional depth and modal ambiguity. It also corresponds to the Indian raga Bhairav and the Carnatic Mayamalavagowla, highlighting its cross-cultural presence in South Asian music as the 15th melakarta scale. Alternative names include the Byzantine scale, Gypsy major, Hungarian folk scale, and , reflecting its adoption in Eastern European and Romani (Gypsy) traditions, as well as styles. In Western music, the double harmonic scale has been employed to introduce non-Western sonorities, notably in Impressionist compositions such as Claude Debussy's Ondine from Préludes, Book II, where it enhances exotic and mythical atmospheres through its palindromic Hijaz tetrachord elements. Similarly, André Caplet's Suite Persane (1900) utilizes the scale in movements like Iskia Samaïsi to capture Persian melodic contours and lyrical exoticism. Beyond classical contexts, it appears in popular and film music, such as Nikos Roubanis's "Misirlou" and Deep Purple's "Gates of Babylon," underscoring its versatility in creating dramatic, influential soundscapes across genres.

Definition and Construction

Interval Structure

The double harmonic scale is a heptatonic scale characterized by the interval pattern of one semitone, minor third, one semitone, major second, one semitone, minor third, and one semitone, expressed numerically as 1-3-1-2-1-3-1 in semitones. This structure can also be denoted using step sizes as H (half step), W+H (whole step plus half step), H, W, H, W+H, H, where H represents a semitone and W a whole tone. It is constructed by altering the through the flattening of the second and sixth scale degrees, resulting in the pitch classes 1, ♭2, 3, 4, 5, ♭6, 7. For example, in the key of C, the scale consists of the notes C, D♭, E, F, G, A♭, B.

Names and Notations

The double harmonic scale is known by several names reflecting its cross-cultural adoption in various musical traditions. In Western music theory, it is primarily termed the double harmonic scale or double harmonic major scale, emphasizing the presence of two augmented seconds in its structure. This nomenclature highlights its derivation from the major scale with alterations to the second and sixth degrees. It is also referred to as the Byzantine scale, a name derived from its association with Byzantine chant and Greek folk music traditions. In Arabic musical systems, the scale corresponds to the Hijaz Kar (or Hijazkar) maqam, the most prevalent variant of the Hijaz maqam, where it is constructed from the Hijaz jins on the tonic followed by the Nikriz jins on the fourth degree. The Gypsy major scale is another common designation, particularly in the context of Eastern European Romani music, underscoring its exotic, emotive quality in violin and guitar traditions. Regional variants further illustrate its nomenclature diversity. The term double harmonics occasionally appears in Western pedagogical materials to denote the scale's dual augmented intervals. These names trace back to the scale's integration into Ottoman and theoretical frameworks during the 19th century, where makam systems formalized such structures, though the specific "double harmonic" label emerged in Western analysis during the 20th century as documented non-Western scales. Notation for the double harmonic scale typically employs flats to indicate the lowered second and sixth degrees relative to the , as in the C double harmonic: C–D♭–E–F–G–A♭–B–C. Alternative notations may use sharps in certain transpositions to align with key signatures or enharmonic equivalents; for instance, the D double harmonic can be written as D–E♭–F♯–G–A–B♭–C♯–D to facilitate reading in contexts with fewer accidentals. Due to its two augmented seconds, the scale lacks a fixed position in the circle of fifths, which organizes diatonic keys, and is instead treated as an exotic or synthetic mode outside standard tonal hierarchies. To avoid confusion, the double harmonic scale is distinct from the , which alters the seventh degree of the natural minor rather than modifying the major scale's second and sixth degrees.

Theoretical Properties

Symmetry and Balance

The double harmonic scale demonstrates a high degree of internal through its palindromic interval pattern of 1-3-1-2-1-3-1 semitones (minor second, augmented second, minor second, , minor second, augmented second, minor second), which remains identical when reversed. This structure creates reflectional centered on the note, often described as radial , where the scale's design mirrors itself around the central axis at 0. Such contributes to the scale's balanced and exotic sonic profile, distinguishing it from asymmetric Western scales. In pitch-class set theory, the double harmonic scale is represented by the set class 7-22, with prime form {0,1,4,5,7,8,11}. Its interval vector <4,2,4,5,4,2> reveals a balanced distribution of interval classes: four minor seconds, two major seconds, four minor thirds, five major thirds, four perfect fourths, and two tritones. This even spread of smaller and larger intervals enhances the scale's equilibrium, with the augmented seconds positioned symmetrically to frame clusters of semitones and the single whole tone providing central stability. The scale's center of gravity distance measures 0, confirming perfect axial balance around the root without deviation. Visually, an interval diagram of the scale—plotting cumulative semitones from the root—highlights its palindromic elements, forming a symmetric waveform that peaks evenly between the augmented seconds while the semitones create tight clusters at the edges and center. In contrast to the diatonic scale (set class 7-35, interval vector <443434>), which exhibits no such reflectional symmetry and evolved from just intonation adaptations in Western music, the double harmonic scale's properties stem from modal traditions emphasizing inherent balance over tempered equality.

Tetrachords

The double harmonic scale is constructed from two disjunct s that form its foundational structure. The lower spans the first four degrees (1, ♭2, 3, 4) and corresponds to the hijaz , featuring the interval pattern of a half step (H), augmented second (A2), and half step (H). The upper covers the remaining degrees (5, ♭6, 7, 8=1) and aligns with the harmonic minor transposed to the fifth degree, exhibiting intervals of a half step (H), augmented second (A2), and half step (H). Both the lower and upper are hijaz jins (H-A2-H), making the scale a union of two hijaz connected disjunctly by a whole tone. These tetrachords are connected disjunctly by a whole tone interval between the fourth and fifth degrees, creating an overall span of an without overlap. This arrangement generates the complete double harmonic scale through the union of two hijaz tetrachords, emphasizing the scale's characteristic augmented seconds in both segments. In theoretical terms, the hijaz tetrachord's pattern (H, A2, H) imparts an exotic, tense quality often associated with Middle Eastern modalities, while the upper tetrachord's (H, A2, H) mirrors the ascending structure found in the harmonic minor scale's upper portion. This tetrachord-based construction is rooted in Arabic maqam theory, where short melodic segments known as jins (tetrachords or similar) serve as modular building blocks for larger maqamat, such as Hijaz Kar, which directly corresponds to the double harmonic scale.

Modes

The Seven Modes

The double harmonic scale, with its defining interval structure of half, augmented second, half, whole, half, augmented second, and half steps, yields seven rotational modes, each beginning on successive degrees of the scale. These modes preserve the scale's exotic, tense character through the presence of augmented seconds but vary in their overall tonality, from major-like to highly dissonant. While analogous names drawn from the modes (Ionian, Dorian, etc.) are sometimes applied for familiarity, many have distinct traditional or theoretical designations reflecting their unique properties. The modes are detailed below, showing the starting degree relative to the parent scale (assuming root as 1), the sequence of degrees in the parent scale, the interval formula relative to the mode's own tonic, and notable alternative names.

The seventh mode stands out for its extreme dissonance, featuring a diminished fifth (♭5) and (♭♭7) relative to its tonic, along with additional flattened intervals that create instability and tension typical of Locrian structures but amplified by the parent scale's augmented seconds.

Mode Applications

The modes of the double harmonic scale offer versatile potential in composition and , primarily due to the two augmented seconds that generate pronounced dissonance and tension, evoking an exotic, Eastern-influenced flavor. This tension arises from the scale's interval structure (1-b2-3-4-5-b6-7), where the augmented seconds between b2-3 and b6-7 create unstable melodic and intervals that demand careful resolution to maintain coherence. Common chord types derived from these modes include augmented triads on the (1-3-#5), which amplify the scale's dramatic through symmetrical , and dominant seventh chords with a flat (1-3-5-b7-b9), suitable for heightened expressiveness over altered dominant functions. In chord-scale theory, the modes align specific scale degrees to chord tones for targeted improvisation and harmonization. For instance, over a double harmonic major chord, the subset 1-b2-3-5 provides a core voicing that incorporates the characteristic flat second for color while supporting the major third and perfect fifth, often extended to include the major seventh and flat sixth (1-b2-3-5-b6-7) for fuller texture. This approach extends to other modes, where scale degrees outline altered extensions; for example, Mode 1 functions over a major seventh chord with added flat ninth and flat thirteenth (1-b9-3-11-5-b13-7), emphasizing tension on the b9 and b13. Similarly, Mode 5 suits a dominant seventh with flat ninth, sharp eleventh, and thirteenth (1-b9-3-11-b5-13-b7), ideal for tritone substitutions in jazz progressions. Mode-specific applications leverage these properties for distinct effects in composition and improvisation. Mode 1 excels in creating exotic resolutions, transitioning between major tonalities via pivot chords like stacked major sevenths a half-step apart (e.g., Cmaj7 to Dbmaj7), which resolve the inherent dissonance into brighter or darker harmonic spaces. Mode 4, the Hungarian minor, features a natural second, flat third, raised fourth, and flat sixth, introducing bright tension in jazz contexts through its raised fourth and major seventh, often applied over major seventh chords with sharp eleventh and flat thirteenth (1-9-b3-#11-5-b13-7) to evoke a shimmering, unresolved lift suitable for modal vamps. Mode 7, by contrast, produces unstable, chromatic effects via double flats and sharps (e.g., equivalent to a dominant seventh with dual ninths and thirteenths), making it effective for dissonant bridges or avant-garde improvisations that heighten drama without traditional resolution. Practical tips for employing these modes include approaching scale tones with chromatic lower neighbors to accentuate the augmented seconds' tension without forcing direct resolution on them, preserving the scale's enigmatic quality; for example, precede with the flat second as a passing tone over a root-position chord. They also integrate well with pedal points, sustaining a drone on the or fifth to ground the dissonance during modal shifts in extended solos or ambient compositions. A brief theoretical progression in Mode 1 might involve i (minor triad on , incorporating b2) - III (major on degree) - iv (minor on the fourth), cycling tension through the augmented second before resolving to the tonic.

Cultural and Musical Uses

Traditional Contexts

The double harmonic scale emerged within Middle Eastern maqam systems, notably as the Hijaz Kar in and Hicaz in Turkish music, with significant influences from Persian and Ottoman traditions spanning the 16th to 19th centuries. These origins trace back to ancient modal practices in the region, where the scale's distinctive augmented seconds provided a framework for expressive melodic development in court and folk traditions. Its interval structure aligns closely with key jins in maqam theory, enabling fluid and modulation. In , the scale underpins maqams such as Hijaz Kar, forming the core of improvisational on instruments like the and qanun. These performances emphasize emotional depth, often evoking longing or intensity through the scale's tense intervals, and are central to classical ensembles in the and . Similarly, in Turkish , the Hicaz makam utilizes the scale for intricate compositions and vocal solos, reflecting cultural exchanges across the empire. The scale appears in flamenco and Romani (gypsy) music traditions as the "Gypsy scale," where it drives the passionate phrasing of Spanish flamenco guitar, heightening the genre's raw emotional power in cante jondo styles. Originating in 18th-century Andalusian gypsy communities, its use underscores themes of hardship and resilience in oral storytelling through music. In Balkan and Eastern European contexts, it infuses Jewish folk repertoires and extends to Romanian folk traditions for similar expressive purposes. Traditional renditions of the scale frequently incorporate microtonal tunings, with quarter-tone approximations—particularly in the augmented seconds—essential for authentic intonation on fretless instruments like the oud. This nuanced approach, rooted in regional modal practices, distinguishes the scale's sound from equal-tempered approximations and preserves its cultural resonance.

Modern and Western Applications

In Western classical music, the double harmonic scale has been employed to evoke exotic, Orientalist atmospheres, particularly in impressionist works seeking to capture non-Western influences. incorporated the scale in pieces such as "La soirée dans Grenade" from his 1903 suite Estampes, where it contributes to the evocation of Spanish and musical flavors through its characteristic augmented seconds. This usage aligns with Debussy's broader interest in global sonorities, blending them into harmonic progressions that enhance atmospheric tension without strict adherence to tonal conventions. In and fusion, the double harmonic scale appears in modal and as a source for melodic lines over altered dominant chords, adding an ethnic-infused intensity. Jazz educators and performers, such as saxophonist Bobby Stern, highlight its palindromic structure (1-b2-3-4-5-b6-7) for generating futuristic yet ancient-sounding phrases over tonic major or dominant 7♭9 chords leading to minor resolutions. The Phrygian dominant mode (a close relative) further bridges it to flamenco- fusions, where artists draw on its augmented second for rhythmic, percussive solos. Rock and metal genres have adopted the scale for its dramatic, Middle Eastern tonality, often in neoclassical or surf styles to heighten exotic . Guitarist of and prominently featured it in "Gates of Babylon" (1978) and "Stargazer" from Rising, employing the scale's modes for sweeping, oriental-inspired leads that blend with modal ambiguity. Similarly, Dick Dale's 1962 surf rock instrumental "" popularized the double harmonic major scale through its iconic , adapting traditional Greek folk elements into high-energy phrasing. In and media scoring, the double harmonic scale is frequently used to underscore Middle Eastern or mystical themes, leveraging its tense intervals for cultural authenticity and emotional depth. Composers select it alongside related modes like the Byzantine scale for evoking ancient or exotic settings, as seen in instructional resources for music that demonstrate its application in leitmotifs and ambient cues. Contemporary techniques in electronic music incorporate the scale for ethnic fusion, where synthesizers and software model its intervals to create hybrid world-electronica textures. Producers use it in tracks blending ambient drones with percussive elements, as exemplified in original electronic compositions that exploit its "darkest" sonic profile for immersive soundscapes. Digital audio workstations support this through plugins like Scaler 2, which includes the double harmonic major scale and its modes for chord generation and melody suggestion, facilitating its integration into modern production workflows.

Similar Scales

The , with the interval pattern 1, 2, ♭3, ♯4, 5, ♭6, 7, is a mode of the double harmonic scale, specifically its fourth mode, sharing the characteristic ♭6 and ♯4 intervals while featuring a natural second and flattened third that contribute to its exotic, tense quality often associated with Eastern European folk traditions. The , known as the fifth mode of the and structured as 1, ♭2, 3, 4, 5, ♭6, ♭7, closely resembles the double harmonic scale through its ♭2, , and ♭6, but substitutes a flattened seventh for the , resulting in a brighter, more dominant-flavored tonality commonly used in and Spanish music. The Neapolitan minor scale, outlined by the intervals 1, ♭2, ♭3, 4, 5, ♭6, ♭7, parallels the double harmonic scale in its lowered second and sixth degrees, evoking a dark, dramatic sound, though it incorporates a third and flattened seventh that align it more closely with altered minor modes in Romantic-era compositions. In Eastern musical traditions, parallels include the Indian raga , which follows the harmonic pattern 1, 2, ♭3, 4, 5, ♭6, 7 and shares the ♭6 and with the double harmonic scale, differing primarily in its natural second and flattened third to produce a melodic framework suited for evening performances.

Key Differences

The double harmonic major scale distinguishes itself from the through key structural alterations that enhance its tension and exotic flavor. Specifically, it features a major third and alongside a flattened second, contrasting the harmonic minor's minor third, natural second, and single augmented second between the flattened sixth and raised seventh. These changes introduce an additional augmented second between the and flattened second, yielding a brighter yet more dissonant profile compared to the harmonic minor's characteristically somber and resolved intervals, which support traditional dominant-to-tonic resolutions. In comparison to the Hungarian minor scale—often regarded as the fourth mode of the double harmonic major—the primary divergences occur at the second and third degrees relative to their respective roots. The double harmonic major employs a flattened second and major third, while the Hungarian minor uses a natural second and minor third, both sharing a raised fourth but resulting in divergent chord constructions. This structural variance produces different voicings, such as the double harmonic major's emphasis on augmented and dominant chords with a major tonality, versus the Hungarian minor's minor-key focus with heightened dissonance from the raised fourth over harmonic minor foundations. Sonically, the double harmonic scale's dual augmented seconds create a distinctive "exotic" snarl, evoking intense, otherworldly tension that sets it apart from scales like the Phrygian dominant (the fifth mode of harmonic minor), which relies on a single augmented second for a more melancholic, flamenco-inflected dominance. This dual-interval configuration amplifies the scale's modal ambiguity and dramatic pull, often imparting a gypsy or Middle Eastern character absent in the Phrygian dominant's singular leap. Theoretically, the double harmonic scale departs from diatonic constructs like scales, which arise from successive perfect fifths in the circle of fifths, by incorporating fixed augmented seconds that disrupt smooth and modulation. Its non-diatonic nature precludes easy integration into Western functional , as the large intervals resist authentic cadences and pivot chords typical of key changes. In usage, the double harmonic scale favors static modal vamps—sustained harmonies emphasizing color and texture—over the dynamic functional progressions of Western keys, where chordal tension resolves through V-I movements. This modal orientation suits its application in evocative, non-progressive contexts like ethnic or scoring, limiting its role in tonal modulation schemes.
