The maqam system of the Arab world and the makam system of Turkish music represent one of the most sophisticated approaches to melodic organization in the world — far more than a set of scales.
BEYOND THE SCALE
In Western music education, scales are the starting point: a defined sequence of intervals from which melodies can be drawn. The maqam system — used across Arab, Turkish, Persian, and much of Central Asian music — contains scales, but a maqam is not simply a scale. It is a melodic personality.
A maqam (plural: maqamat; Turkish: makam, plural: makamlar) specifies: the pitches available (including microtonal inflections); the characteristic ascending and descending paths (which may differ from each other and may not use all available pitches); the habitual ornaments associated with the mode; the emotional character (Arabic: tab', "color" or "nature"); the typical register in which the melody moves; the "resting tones" and "finalis" that give the melody its sense of cadence and arrival; and often a time of day, season, or occasion for which the maqam is appropriate.
This is not a scale. It is a complete set of instructions for melodic behavior.
THE STRUCTURE OF MAQAMAT
Arab maqam theory describes maqamat as combinations of tetrachords (ajnas, singular: jins) — four-note cells, each with a characteristic interval pattern. The most important tetrachords are:
Rast: roughly equivalent to the Western major tetrachord, but with the third degree slightly lowered (approximately a three-quarter tone flat relative to equal temperament).
Bayati: a tetrachord beginning with a three-quarter-tone interval — the characteristic "oriental" sound that Western listeners often associate with "Middle Eastern music" generically.
Hijaz: a tetrachord with an augmented second (one and a half tones) between its second and third degrees — the most immediately recognizable sound of the maqam system to outside ears.
Saba: a particularly complex tetrachord with multiple microtonal inflections, considered one of the most emotionally intense of all ajnas.
A complete maqam is typically built by stacking two tetrachords (or a tetrachord and a pentachord) to span an octave, but the identity of the maqam depends as much on the characteristic melodic motion as on the theoretical interval structure.
MICROTONES AND TUNING
The maqam system uses intervals smaller than the Western semitone. In Arab music theory, the octave is theoretically divided into twenty-four equal quarter-tones (though in practice, the inflections are more complex and variable than a simple twenty-four-tone system implies). The three-quarter-tone interval — halfway between a semitone and a whole tone — appears in several of the most important ajnas and is the most significant single deviation from Western equal temperament.
The Turkish makam tradition, documented in detail by Istanbul Technical University's Center for Advanced Studies in Music (MIAM), uses a fifty-three-tone equal temperament as its theoretical basis (derived from Pythagorean fifths), producing a system of "commas" (approximately nine of them per whole tone) that gives Turkish music its distinctive microtonal flexibility.
Dr. Arel's twentieth-century systematization of Turkish makam theory — adopted by the Turkish State Conservatories — provides the standard theoretical framework for Turkish classical music training. MIAM's research program at Istanbul Technical University continues to refine and document the makam system using computational and acoustical methods.
ARAB CLASSICAL MUSIC: MAQAM IN PRACTICE
Arab classical music reached a mature form by the tenth century (as documented in al-Farabi's Kitab al-Musiqa al-Kabir) and a different kind of maturity in the late nineteenth and early twentieth century with the Egyptian classical tradition centered on Cairo. The great Egyptian singer Umm Kulthum (1904–1975) is considered the supreme artist of the Arab classical tradition. Her concerts regularly lasted four to six hours, with a single song repeated and extended over an hour as she improvised within the maqam in response to audience reactions. The relationship between performer and audience in Arab classical music — the tarab (ecstasy, enchantment) that a great singer produces — is a social and aesthetic phenomenon without close parallel in Western classical music.
The oud (Arabic lute, the direct ancestor of the European lute) is the central melodic and solo instrument of Arab classical music. The violin, adopted in the nineteenth century, plays a central role in Arab ensembles, but restrung to facilitate maqam inflections and played with different intonation than in Western classical practice.
MODAL THEORY'S LONG HISTORY
Arab music theory, transmitted through the work of al-Kindi (ninth century), al-Farabi (tenth century), and Ibn Sina (eleventh century), was one important channel through which ancient Greek music theory (including Ptolemy's Harmonics) reached medieval European scholars; the European church modes themselves descend from the same Greek heritage mainly via Boethius and the Byzantine oktoechos. The history of modal music is not two separate histories (Western and Eastern) but one continuous — if branching — intellectual tradition.
THE ENSEMBLE AND ITS INSTRUMENTS
The Arab takht ensemble — the small ensemble of Arab classical music — typically consists of oud, qanun (plucked box zither with roughly seventy to eighty strings arranged in courses of three), violin (kamanja, restrung and retuned for maqam intonation), nay (end-blown reed flute), and riq (tambourine-like frame drum). Each instrument has a specific role: the oud carries the principal melodic line, the qanun adds shimmering ornamental fills and reinforces the melody, the nay sustains long tones and adds melismatic ornament, the violin provides expressive vocal-like passages, and the riq holds the rhythmic foundation. The Turkish equivalent ensemble (fasıl ensemble) adds the tanbur (long-necked lute) to the oud and kanun, with the kemençe (small bowed instrument) replacing the violin in classical contexts.
IQA' AND USUL: RHYTHMIC MODES
Just as maqam organizes pitch, the concept of iqa' (Arabic) or usul (Turkish) organizes rhythm. An iqa' is a fixed rhythmic cycle of a specified length, with a characteristic pattern of strong (dum), weak (tek), and silent strokes. Common iqa'at include the four-beat wahda (used for slow vocal pieces), the eight-beat masmudi, the ten-beat samai thaqil (used for the Ottoman saz semaisi form), and the sixteen-beat muhammas. The Turkish usul system is more elaborate still, with cycles ranging from two beats to over a hundred and twenty beats. The longer usul are felt as continuous melodic-rhythmic forms rather than as repeating cycles in the Western sense — they are time-spans within which a single melody unfolds.
TARAB AND THE LISTENING PRACTICE
Tarab — variously translated as "ecstasy," "enchantment," or "musical rapture" — is the central aesthetic concept of Arab classical music. A great singer or instrumentalist creates tarab in the audience; a great audience, by its responsiveness, draws greater tarab from the performer; the resulting feedback loop produces moments of intensity that participants describe as transformative. The audience's role is not passive: shouts of approval (Allah! Ya 'ayni! Ya salam!), exclamations at particular melodic moves, and rhythmic clapping all participate in shaping the performance. Recording technology, which fixes a performance in a form that cannot respond to its audience, has had ambiguous consequences for the maqam tradition: it has preserved performances that would otherwise be lost, but it has also encouraged a more "perfect," less responsive style of performance.
AL-FARABI AND ISLAMIC MUSIC THEORY
Abu Nasr al-Farabi (c. 872–950 CE) wrote the Kitab al-Musiqa al-Kabir (The Great Book of Music), the most comprehensive music-theoretical treatise of the medieval Islamic world. The work combines Greek (Pythagorean, Aristoxenian, Ptolemaic) sources with original Arab observations of practical music-making, and it provides one of the earliest mathematically rigorous analyses of microtonal intervals. Al-Farabi's distinction between accidental notes (those used briefly in passing) and structural notes (those that define the modal character) anticipates concerns that would later occupy both Persian and European modal theorists. The transmission of al-Farabi's work through medieval Spain shaped European thinking about music for centuries.
EXERCISE: MAQAM IDENTIFICATION
Listen to three short recordings labeled only as "Maqam A," "Maqam B," "Maqam C" — find examples of Maqam Rast, Bayati, and Hijaz on Smithsonian Folkways or through a university music library. For each, identify: the approximate starting pitch; whether you can hear an augmented second; whether the melody seems to rise and fall differently; and what emotional character you perceive. Compare your perceptions to the theoretical descriptions in Scott Marcus's chapter in "Worlds of Music."
