The classical music of Iraq, known as Iraqi Maqam, features classical and vernacular poetry sung by a virtuoso soloist and accompanied by a small instrumental ensemble. It is a remarkably cosmopolitan art, sharing many features with neighboring classical traditions, particularly Iranian. Its repertoire consists of orally transmitted, multi-sectioned compositions, performed with some flexibility regarding ornamentation, arrangement and development. Focusing on the period between 1930-1980, this reference offers the first comprehensive view of the musical contents of the repertoire—scalar structure, melodic materials and overall form—through various tables and musical transcriptions. This reference consolidates information from prominent Iraqi sources and draws upon a selection of recordings by master musicians, including Rashid Qundarchi and Yusuf Omar. An introductory section provides a brief overview of pan-Middle Eastern modal theory along with an outline of the terminology, theory and practices specific to Iraqi Maqam. The main section of the work is a catalog of 40 maqams that constitute the central core of the contemporary repertoire. The Repertoire of Iraqi Maqam aims to foster a better musical understanding of a relatively little known tradition, promote further research, and enhance appreciative listening to this inspiring facet of Iraqi culture.
