William Jeffery is an Australian composer based in Coffs Harbour. In 2014, William was invited to be the Newcastle Youth Orchestra’s inaugural Composer in Residence. The main goal of this Residency was to compose an eight-minute, celebratory work for the Orchestra’s Proms Concert. This project was kindly assisted by the Australian Government through the Australia Council for the Arts, its arts funding and advisory body, and in 2016 the work received a second performance.
In 2013, William was invited to participate in the Australian String Quartet's National Composers' Forum. The Quartet premiered Fidyll (String Quartet No 1) after a series of workshops in Adelaide with composer and broadcaster Andrew Ford, while in Sydney, the Sydney Contemporary Orchestra premiered Octobbligato (Octet No 1). Also in this year, Short and Suite, a work for solo viola, placed first in the inaugural Australian and New Zealand Viola Society's Composition Competition and was premiered in April by violist Gregory McGarity at the Auckland Viola Convention.
The first performance of one of William’s works was by the Sydney Sinfonia and Richard Gill, who in 2011 performed Vagary as part of the Sydney Symphony Orchestra’s Sinfonietta Project.
