Musical numbers, as viral modes of entertainment, influential forms of visual culture and catalysts of popular discourse are dense with multivariate aesthetic performers, and are interlaced to punctuate the melodramatic narrative texture in advancement of the plot and characterization in musical films. Performing identity through dancing bodies has been the subject of several film, music, culture, performance and communication research endeavours yet has rarely been explored from multimodal discourse analysis perspectives. To examine the ‘resilient identities’ underlying performances, the article adopts an eclectic approach informed by the Bakhtinian chronotope with regard to two numbers drawn from a recent American musical film in order to pinpoint: (a) the full repertoire of multimodal resources of narrative agency and identity performance; (b) the emotional experiences evoked by the musical numbers; and (c) the social practices that constitute, maintain and resist social realities and identities. The unconventional approach to the analysis of the musical numbers is what makes the current research project stand out among interdisciplinary studies of musical discourse.

音乐数字，作为一种娱乐性的病毒形式，有影响力的视觉文化形式和流行话语的催化剂，充满了多元的审美表演者，并在音乐电影的情节和特征化过程中交织在一起，突显出戏剧性的叙事纹理。通过跳舞的身体表演身份一直是电影，音乐，文化，表演和传播研究的主题，但很少从多模态话语分析的角度来探讨。为了考察“弹性身份”的基本表现，本文采用了巴赫金年代记的折衷方法，对最近一部美国音乐电影中的两个数字进行了归纳，以查明：（a）叙事机构多模态资源的全部曲目和身份表现；（b）音乐数字引起的情感体验；（c）构成，维持和抵制社会现实和身份的社会实践。对音乐数字进行分析的非常规方法使当前的研究项目在音乐话语的跨学科研究中脱颖而出。
