. Much of Arabic music is characterized by an emphasis on
melody and
rhythm, as opposed to
harmony. There are some genres of Arabic music that are
polyphonic, but typically, Arabic music is
homophonic.
Habib Hassan Touma submits that there are five components that characterize Arabic music: • The
Arab tone system; that is, a
musical tuning system that relies on specific interval structures and was invented by
al-Farabi in the 10th century
Ajnas The maqam consists of at least two
ajnas, or scale segments.
Ajnas is the plural form of
jins, which in Arabic comes from the Latin word
genus, meaning "type". In practice, a jins is either a
trichord (three notes), a
tetrachord (four notes), or a
pentachord (five notes). A maqam usually covers only one
octave (usually two ajnas), but can cover more. Like the melodic minor scale, some maqamat use different ajnas when descending and ascending. Due to continuous innovation and the emergence of new ajnas, and because most music scholars have not reached consensus on the subject, a solid figure for the total number of ajnas in use is uncertain. In practice, however, most musicians would agree there are at least eight major ajnas:
rast,
bayat,
sikah,
hijaz,
saba,
kurd,
nahawand, and
ajam, and commonly used variants such as
nakriz,
athar kurd,
sikah beladi,
saba zamzama. For example,
Mukhalif is a rare jins (in the Sikah) family used almost exclusively in Iraq, and it is not used in combination with other ajnas.
Microtones in Arabic music Unlike the tradition of Western music, Arabic music contains
microtones, which are notes that lie between notes in the Western
chromatic scale. While notes in the chromatic scale are separated by
semitones (or half steps), notes in Arabic music can be separated by
quarter tones. In some treatments of theory, the quarter tone scale or all twenty four tones should exist, but according to
Yūsuf Shawqī (1969), fewer tones are used in practice. Both in modern practice, and evident in recorded music over the course of the last century, several differently-tuned Es in between the E-flat and E-natural of the Western Chromatic scale are used, that vary according to the types of maqams and ajnas used, and the region in which they are used.
Practical treatment Musicians and teachers refer to these in-between notes as
quarter tones, using "half-flat" or "half-sharp" as a designation for the in-between flats and sharps, for ease of nomenclature. Performance and teaching of the exact values of intonation in each jins or maqam is usually done by ear. It should also be added, in reference to
Habib Hassan Touma's comment above, that these quarter tones are not used everywhere in the maqamat: in practice, Arabic music does not modulate to 12 different tonic areas like the
Well-Tempered Klavier. The most commonly used quarter tones are on E (between E and E), A, B, D, F (between F and F), and C.
Vocal traditions Arab classical music is known for its famed virtuoso singers, who sing long, elaborately ornamented, melismatic tunes, coloraturas unheard in any other musical genres and are known for driving audiences into ecstasy. Its traditions come from pre-
Islamic times, when female singing
slaves entertained the wealthy, inspired warriors on the battlefield with their rajaz poetry, and performed at weddings. A vast number of female Arab vocalists are mezzo-sopranos who cultivate darker and richer tones than generic Soprano voices.
Instruments and ensembles playing a
mandolin-banjo in
Ghazal al-Banat. The prototypical Arabic music ensemble in Egypt and Syria is known as the
takht, and includes, (or included at different time periods) instruments such as the
'oud,
qānūn, rabab,
ney, violin (introduced in the 1840s or 50s),
riq and
dumbek. In Iraq, the traditional ensemble, known as the
chalghi, includes only two melodic instruments—the jowza (similar to the rabab but with four strings) and
santur—accompanied by the
riq and
dumbek. The Arab world has incorporated instruments from the West, including the electric guitar, cello, double bass and oboe, and incorporated influences from jazz and other foreign musical styles. The singers have remained the stars, however, especially after the development of the recording and film industry in the 1920s in
Cairo. These singing celebrities are (or were) the biggest stars in Arabic classic music, they include
Farid Al Attrache,
Asmahan,
Abdel Halim Hafez,
Sayed Darwish,
Mohamed Abdel Wahab,
Warda Al-Jazairia,
Wadih El Safi,
Fairuz,
Sabah, and
Umm Kulthum. == Research and documentation of Arabic music ==
