B3-H4RSH: A Noise-based Multiplayer Game
for Mobile Music-Making

by Luca Morino, Nicola Conci and Fabio Cifariello Ciardi

Over the past two decades, artists and composers have increasingly explored mobile phones — ubiquitous and accessible devices — as instruments for music Performance and, in particular, as interfaces for audience participation and collaborative music-making. This paper presents B3-H4RSH, an interactive mobile music system. Implemented as a web application for smartphone browsers on a co-located network, the system interconnects participants’ devices, employing competitive multiplayer mechanics to structure interdependencies among players and shape the music-making act within a noise-music paradigm. By influencing and responding to one another’s actions, participants collectively diffuse sound throughout the space from their smartphones while competing to achieve the “harshest” sonic outcome – and win.
