Microtonal Projects



our aims and who we are

Microtonal Projects was formed by composer Donald Bousted in 2004 with the objective of creating a focus for microtonal music in the UK. Microtonal Projects curated and promoted 4 UK MicroFest events between 2004-2012 in collaboration with Riverhouse Arts Centre in Walton-on-Thames, London Metropolitan University and Kingston University, The Vortex Jazz Club and The Royal Academy of Music. UK MicroFests were performance-focused but also offered an opportunity for composers, theorists and instrument builders to talk about their work. UK MicroFests have attracted audiences and participants from all over the world and have created the opportunity for excellent networking in an informal atmosphere: we are aware of many projects and collaborations which have resulted from such introductions.

In attempting to introduce microtonal music to a wider audience, Microtonal Projects co-curated (with 5 guest artist-curators) 5 Wild Dog events with the support of The Space in London’s Docklands. These events featured microtonal music alongside live art, film, dance and mixed media.  This approach to curation was also taken in a Late at Tate event – Microtonal – (at Tate Britain, London, curated by Donald Bousted and Stephen Altoft) which attracted an audience of around 2,000 people.

In 2013 Microtonal Projects promoted the first EUROMicroFest as a bi-annual event.
