The analysis is based on field recordings and other ethnography collected by the author in 2006-2011. The music of the contemporary Arab-Anglican churches in Israel comprises different styles, which might be decoded as indices of group identity, and transmits different signifiers of belonging to diverse branches of the contemporary world Anglican tradition. A remarkable feature of this Christian community is the ongoing shift of subaltern identities when their most ＂Western＂ component--association with a particular sub-division of the Church--receives its musical expression by means of ＂local motif＇, that is, the tunes associated with regional repertories. The dynamics of ethno-religious identity of Arab-Anglicans in Israel manifests itself through several tendencies, such as ecumenical tendency and some other trends. Though the study is situated in the context of an interdisciplinary academic discourse, music is the main text addressed. ＂Reading＂ this music allowed the author to uncover tenets, trends, and interrelations within the communities under study.展开更多
