Firing "Aesthetic Bullets": In-tone (Ngaam-jam) and the Linguistic Weaponization of Hong Kong's Worship Wars

In the global study of "Worship Wars," congregational conflicts typically center on musical genre and theology. This paper argues that in Hong Kong, this conflict is fought on a fiercely linguistic-aesthetic battlefield, where the demand for in-tone singing functions as an "aesthetic bullet." Reflecting the musicological principle of Hip-wan (協韻), Cantonese,a language with six contrastive lexical tones,requires a strict relational manifestation of tone to maintain the speech-melody complex. Misalignment distorts sacred meaning, allowing factions to weaponize acoustic integrity: progressives critique "out-of-tone" hymns as archaic, and disconnected from local belonging, while traditionalists attack "in-tone" CCM aesthetic as secularized . This study analyzes how acoustic integrity, “in-tone” aesthetics operate within Mandarin worship hegemonies, local music economies, and global diasporic migrations. Ultimately, in-tone practice transcends musical preference; these "bullets" exert tangible political influence by fortifying acoustic resistance against cultural assimilation, articulating a resilient, post-secular Hong Kong Christian aesthetic and identity.
