Maqam: The Melodic Modal System of Arabic Music
In the rich tapestry of traditional Arabic music, the maqam (plural: maqamat) serves as the fundamental system of melodic modes. Derived from the Arabic word for "place," "location," or "position," a maqam is more than just a scale; it is a comprehensive technique of improvisation. It defines the specific pitches, melodic patterns, and the overall development of a musical piece, making it a cornerstone of Arabic art music.
Unlike Western music, which often focuses on harmony and chord progressions, the maqam system emphasizes the tonal-spatial factor—the relationship between notes and the traditional patterns used to navigate them. While the pitches are strictly defined, the rhythmic-temporal component remains flexible, meaning a maqam does not have a fixed meter or a recurring bar scheme.
ไม่มีภาพประกอบKey Facts
- Definition: A system of melodic modes used in Arabic, Persian, and Turkish musical cultures.
- Scale Variety: There are 72 heptatonic (seven-note) tone rows or scales within the maqamat system.
- Tuning: Maqamat are microtonal and do not follow the twelve-tone equal temperament of modern Western music.
- Structure: Built from smaller melodic units called ajnas (singular: jins).
- Learning Method: Primarily taught orally through extensive listening and imitation.
The Technical Foundation of Maqam
Tuning and Microtonality
The notes of a maqam are not always tuned in equal temperament, meaning the frequency ratios between successive pitches can vary. Most maqamat are based on a seven-note scale that repeats at the octave, though there are exceptions like hijaz kar kurd. These scales are microtonal, incorporating intervals such as augmented, major, neutral, and minor seconds.
Because these intervals do not always align with the semitones of a piano, they are difficult to capture in standard Western notation. To address this, a simplified system was adopted at the turn of the 20th century that divides the octave into 24 equal steps (quarter tones). While practical for transcription, this system is a convention; professional musicians continue to perform the finer microtonal nuances passed down through oral tradition.
Notation and Instrumentation
In the 24-tone notation system, quarter tones are represented by half-flats or half-sharps. Due to the technical limitations of traditional instruments, half-sharps are rare, while half-flats on E, B, and occasionally A are common. This makes maqamat more rigid to transpose than Western scales.
Instruments capable of reproducing these microtones include fretless instruments like the oud and violin, or tunable instruments such as the nay (flute), qanun (zither), and clarinet. Equal-tempered instruments, such as the piano, can play maqamat that do not require quarter tones (e.g., Nahawand or ‘Ajam), but they cannot faithfully reproduce the system's microtonal depth.
Structural Components: Ajnas and Nuclei
The Role of Ajnas
The building blocks of a maqam are called ajnas (singular: jins), meaning "gender" or "kind." A jins is a set of consecutive notes—usually a tetrachord (four notes), but sometimes a trichord (three) or pentachord (five)—that conveys a distinctive mood. A typical maqam consists of a lower jins and an upper jins. The starting note of the upper jins is known as the dominant, the second most important note after the tonic (starting note).
Phases and the Nucleus
A musical passage in a maqam is divided into phases, where the melody explores a specific tonal area or axial pitch. These phases typically rise from the lower register to a climax before descending. The nucleus of a maqam consists of the most central tones that define its identity. Interestingly, two different maqamat can share the same tone row but be distinguished by different nuclei, which in turn changes the emotional impact of the music.
Maqam Families and Emotional Content
Maqamat are often grouped into families based on their lower jins. While there is no scientific consensus on the universal emotional impact of these modes, traditional theory associates specific maqamat with certain moods.
| Maqam Family | Associated Emotion/Mood | Example Maqamat |
|---|---|---|
| Rast | Pride, power, soundness of mind | Rast, Mahur, Yakah |
| Bayati | Vitality, joy, femininity | Bayati, Husayni, Nahfat |
| Sikah | Love | Sikah, Huzam, ‘Iraq |
| Saba | Sadness, pain, tragedy | Saba, Saba Zamzam |
| Hijaz | Distant desert | Hijaz, Hijaz Kar, Zanjaran |
Melodic Development and Global Influence
Modulation
Modulation is the technique of shifting from one maqam to another closely related one during a performance. This adds complexity and interest to the piece. A composition may travel through several maqamat but typically returns to the original starting maqam to provide a sense of resolution.
Cultural Reach
The maqam system's influence spread significantly during the Islamic Golden Age. It impacted the music of the Iberian Peninsula during the rule of Al-Andalus and continues to influence the music of Sicily. Additionally, the Sephardic Jewish liturgy utilizes the system through the "Weekly Maqam," where the cantor selects a mode based on the Torah reading or the congregation's emotional state.
Frequently Asked Questions
What is the difference between a maqam and a Western scale?
While a Western scale is a set of notes, a maqam is a complete melodic system. It includes not only the notes (which are often microtonal) but also traditional phrases, specific notes of emphasis, and rules for melodic development and improvisation.
Can a piano play Arabic maqamat?
Only partially. A piano is tuned to equal temperament and cannot produce the quarter tones essential to many maqamat. However, it can play maqamat that do not use microtones, such as ‘Ajam or Nahawand.
What is a jins in Arabic music?
A jins is a small set of consecutive notes (usually three to five) that serves as the basic building block of a maqam. Each jins has a recognizable melody and is believed to convey a specific mood.
How are maqamat traditionally learned?
Because of the precision required for microtonal intonation, which is often lost in written notation, maqamat are primarily taught orally through listening and imitation of the traditional repertoire.
What is modulation in the context of maqam?
Modulation is the process of changing from one maqam to another compatible maqam during a piece of music to create variety and emotional depth.
