This sheet music highlights world music, especially Arab-Andalusian music, through doubling, text, and important and particular intervals. It is perfect for programs specialized in musical culture diversity. You can call something Arab-Andalusian when it comes from a great part of Spain occupied by Arab people until the end of the 15th century. Several musicologists and musicographers worked on the transcription of this music in Morocco, Algeria and Spain. This revived its interesting aspect for the comprehension of the Western Europe musical development. In Algeria (the native country of Rabah Kadem), it was first called “Andalusian music” then “classical music,” then “Andalusian classical music” and finally “Andalusian-North African music,” with distinctions for each of the three countries: Algerian, Tunisia and Morocco. Rabah Kadem was born in 1948 in Algiers. He is a composer, arranger, orchestrator, choirmaster, and music teacher. He studied at Algiers’s Conservatory. He is a professor for the regional institute of musical training, and he trains the Republican Guard choir. He conducts the polyphonic choir of Algiers, as well as the association and polyphonic choir “Nagham.” He is also a member of the Executive Board of the Algerian council of music and of the administrative council of the National Symphony Orchestra.
