In the past five years, there has been an increasing number of research papers on the virtual ethnography of jazz music and its fans, but few studies have focused on the virtual jazz life in the Chinese context. Traditionally, jazz has been confined to elite spaces such as clubs and conservatories in urban centers like Shanghai, Guangzhou, and Hong Kong. However, the rise of social media and digital platforms has democratized access to jazz, expanding its reach beyond these institutional settings to a broader, more diverse audience. This study employs a virtual ethnographic approach to analyze four distinct cases of jazz-related content on platforms such as RedNote and Bilibili, focusing on memes, short videos, and comment sections. By applying affective media theory, Kivy’s resemblance theory of musical expressiveness, and the framework of participatory culture, the paper demonstrates that jazz is no longer solely a domain for the musically literate. Rather, it is a medium that evokes emotional resonance, symbolic associations, and widespread participation. This research challenges conventional notions of jazz as an exclusive art form, emphasizing its role in creating belonging and reimagining local cultural meanings. The findings suggest that virtual jazz participation disrupts traditional access barriers and allows jazz to circulate as a living, dynamic cultural resource in China.
