Peter Rosser, who has died aged 44, was a well-known composer, writer and music lecturer.
He was born in London and came to Belfast, where he studied music composition at the University of Ulster. He was awarded a DPhil in 1997.
His distinctive music was performed at a wide range of events, including the Spitalfields Festival in London, as well as the Belfast Festival at Queen's and also the Crash Festival in Dublin. In 2011 the Arts Council of Northern Ireland recognised his contribution to the arts scene with a Major Individual Artist Award.
Peter used this resource to compose his Second String Award and this was premiered in 2012 by the JACK Quartet from New York at the opening of Belfast's new Metropolitan Arts Centre.
Dr Rosser also wrote widely about music and his work was published in publications including the Belfast Telegraph, The Wire, the Journal of Music, Perspectives of New Music and the Crescent Journal.
Ciaran Scullion, head of music at the Arts Council, paid tribute to Peter, whose death, he said, was "a genuine loss to the arts in Northern Ireland".
"Peter had achieved so much in his relatively short career, working with people like Irvine Arditti, Mieko Kanno, the Composers' Ensemble and the Ulster Orchestra, and he had a great future ahead of him.
"Peter had a tremendous ability to keep his finger on the pulse of changes to the music scene. It is deeply saddening to think of what might have been from this truly talented and respected composer."
He is survived by his partner Anne McCambridge and the wider family circle.
