Staged performance involves the overt, scheduled identification and elevation of one or more people to perform, with a clearly demarcated distinction between them and the audience. It involves the agentive use of language, building on the foundation of existing social meanings. Staged performances tend to be linguistically stylized, pushing the limits of language creativity. They have the potential to trigger significant sociolinguistic effects, circulating novel forms and contributing to language change. The paradigms used in this theme issue for approaching language performance include Bakhtin's notion of Stylization, Bell's Audience and Referee Design, Silverstein's Indexicality, Agha's Enregisterment, and Bauman's construct of Discursive Culture. Themes that run through the articles include: a concept of identity that is part product, part process; the centrality of the audience; the reflexivity of staged performance; and the importance of non-linguistic modalities such as music and appearance. The language analysis in this collection of papers concentrates mainly on phonological features of varieties of English, finding instances of selectivity, mis-realization, overshoot and undershoot in their performances of a range of targeted dialects.The performance of language has burgeoned as an area of interest in recent sociolinguistics. This should not surprise us. Performance offers the opportunity to deal with frequently fascinating, multi-layered data where stylization of linguistic resources is rife. It invites us to theorize about the nature of language in society on the basis of analytically challenging and rewarding 'texts' which open up some of the most significant dimensions and issues of contemporary societies. Language in performance embodies cultural values and trends, and interacts with wider modalities of music and visuals to form the semiotic horizon of our world. Through all this, performed language is object as well as medium, the focus of reflexive comment and recycling that further layers its social significance.The five papers in this issue comprise a range of performance types, though comedy and popular music are two genres which appear in several of the pieces. Coupland's paper advocates a contextualised approach to investigating how place indexicalities and vernacularity are mediated by genres of popular
