24 Hour Choir was a participatory sound project in which over one hundred members of the public sustained the human voice, uninterrupted, across an entire day. The location was the politically fraught area of The Rocks in Sydney, Australia, from which long-standing social housing tenants had recently been evicted. 24 Hour Choir responded to this situation by establishing a sonic means to build solidarity. Singers followed several open-ended instructions that required them to develop individual cooperative strategies inducing a form of civic duty. The results, sonically influenced by the shifting ambience of the city, became a real-time mapping of social relations. 24 Hour Choir is part of the project Super Critical Mass which brings together temporary communities to undertake shared sonic actions in public spaces. Each event is a structured improvisation in which participants’ skills become the parameters for a memorised, behavioural algorithm, extending precedents by Cornelius Cardew and Pauline Oliveros.

24 小时合唱团：即兴创作中的公民伦理

24 小时合唱团是一个参与式声音项目，一百多名公众在一整天内不间断地持续播放人声。该地点是澳大利亚悉尼岩石区的政治问题，最近长期居住的社会住房租户被驱逐出境。24 小时合唱团通过建立声波手段来建立团结来应对这种情况。歌手遵循几项开放式指令，要求他们制定个人合作策略，从而产生一种公民义务。结果，受到城市环境变化的声音影响，成为社会关系的实时映射。24 小时合唱团是 Super Critical Mass 项目的一部分，该项目将临时社区聚集在一起，在公共场所进行共享的声音行动。
