In Sephardic Middle Eastern Jewish prayer services, each Shabbat the congregation conducts services using a different maqam. A maqam (مقام), which in Arabic literally means 'place', is a standard melody type and set of related tunes. The melodies used in a given maqam aims effectively to express the emotional state of the reader throughout the set liturgy (without changing the text). This article primarily describes the musical practices of Syrian Jews, though the musical traditions of other Arab and Oriental Jewish communities are also based on the maqam system. The Muslims share the same practice of conducting services using the maqam, but differ substantially in many ways.
