Each of the 12 muqams consists of a main section that begins with a long free rhythm introduction, followed by pieces with characteristic rhythmic patterns that gradually increase in speed. Each muqam consists of three parts, including naghma, dastan and mashrap. These pieces are arranged in the same sequence in each muqam, although not all muqams have the same pieces. These parts are known as täzä, nuskha, small säliqä, jula, sänäm, large säliqä, päshru and täkit. Some have an associated instrumental piece known as a märghul following it. Although each named piece has its characteristic rhythmic pattern, the melodies differ, so each piece is generally known by the muqam and the piece: for example, "the Rak nuskha" or "the Segah jula". There are about 20 to 30 pieces of songs and musics, which might take approximately 2 hours to finish performing. It will take about 24 hours to perform all pieces of 12 muqams. After the main section, there are two other sections, originally associated with other musical traditions, but included in muqams by performers such as Turdi Akhun and therefore included in the present 12 muqam tradition. The Dastan section includes songs from several of the romantic dastan narratives found widely in Central and South Asia and the Middle East. Each dastan song is followed by an instrumental märghul. The Mäshräp section consists of more lively dance songs that were originally connected with the performances of sama by dervish musicians of Turkistan.
History and preservation
The precursor to Muqam, the "Great Western Region Melody" developed during the Han and Tang dynasties, from which it was imported and enjoyed in the courts of Central China. It was somewhat influenced by the Arabic maqam modal system that has led to many musical genres among peoples of Eurasia and North Africa. Uyghurs have local muqam systems named after the oasis towns of Xinjiang, such as Dolan, Ili, Kumul and Turpan. The most fully developed at this point is the Western Tarim region's 12 muqams, which are now a large canon of music and songs recorded from the traditional performers Turdi Akhun and Omar Akhun among others in the 1950s and edited into a more systematic system. Although the folk performers probably improvised their songs as in Turkish taksim performances, the present institutional canon is performed as fixed compositions by ensembles. The concubineAmanni Shahan of the Yerqiang kingdom is credited with collecting and thereby preserving the Twelve Muqam, while reshaping its style to draw more from the indigenous traditions of the Tian Shan mountains and purging it of the Perso-Arabic. After the 1949 Chinese Revolution, the state commissioned musicians Wan Tongshu and Turdi Akhun to record the Muqams on tape, so that it could not be lost. They published their first album in 1960. From 2004 to 2008, over 7,000 performers have collaborated in a Chinese state project to proliferate seminars, research projects and recordings of the Muqam. In 2005, UNESCO designated The Uyghur Muqam of Xinjiang as part of the Intangible Heritage of Humanity.
