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.

The player piano and piano rolls occupy a unique space in jazz history, bridging live improvisation with mechanical music reproduction. These technologies preserved intricate jazz performances and allowed artists to reach audiences beyond live venues. Yet, despite their significance, many figures central to their development remain underrecognized.

This paper examines the contributions of J. Lawrence Cook, a prolific yet overlooked Black artist who played a crucial role in the player piano era. As one of the most productive piano roll arrangers of the 20th century, Cook crafted thousands of rolls, many of which were widely circulated by major music roll companies. His work extended beyond simple transcription; he infused rolls with stylistic nuance, capturing the dynamism of jazz performance in ways that mechanical reproduction often struggled to achieve.

Cook’s influence is particularly evident in his connection to Fats Waller. Some of Cook’s rolls were released under Waller’s name, highlighting the complexities of authorship and recognition in jazz history. Furthermore, Cook's contributions were not limited to performance—he also played a key role in advancing piano roll technology, refining techniques that enhanced the expressivity of mechanically reproduced music.

This paper draws on ethnographic and ethnomusicological approaches to analyze Cook’s piano rolls, shedding light on his stylistic innovations and technical contributions. By acknowledging his legacy, I aim to reposition Cook within jazz historiography, illustrating how his work not only shaped the player piano era but also influenced subsequent generations of musicians.

Accounts of early banjo repertory have tended to privilege textual and melodic sources over the embodied techniques through which tunes and songs took shape in performance. As a result, instrumental practice has remained peripheral to accounts of Atlantic musical exchange. Though widely regarded as a definitive study, Hans Nathan’s analysis of the early blackface minstrel repertoire as rooted in Anglo-Celtic and Afro-Caribbean music and dance cultures stops short of explaining how that fusion was realized in instrumental technique. Comparative analysis of notated sources associated with early minstrel banjoists instead points to downstroke playing (a percussive downward striking style) as a principal site at which European and African American musical practices were brought into relation. Building on Cecelia Conway’s account of banjo song as a tradition forged within African American communities and transmitted through interracial exchange, this paper explores how the Irish/Scottish fiddle tune “The Devil’s Dream” was reconfigured as the “Grapevine Twist” through patterned striking motions of the right hand. Rather than treating syncopation as a stylistic trait added to otherwise stable European tunes, the paper argues that their internal organization shifted to accommodate Black banjo technique. What emerged was not simply a change in rhythmic inflection but a restructuring of the tune itself, shaped by the demands of downstroke banjo playing.
