The first violist to win the ABC Young Performers Award in 1972, Keith quickly established himself as one of Australia’s leading soloists and chamber music players. Having studied violin initially with Gretchen Schieblich, and then Ladislav Jasek at the Queensland Conservatorium of Music, he completed his tertiary studies at the Tasmanian Conservatorium of Music under noted pedagogue, Professor Jan Sedivka. Keith was a founding member of the Rialannah String Quartet, performed with the Petra String Quartet, and was a regular member of the Australian Contemporary Music Ensemble.

Subsequently, he was appointed Lecturer in viola and chamber music at the Tasmanian Conservatorium of Music, Director and Principal Conductor of the Conservatorium Orchestra and Artistic Director and Chief Conductor of the Tasmanian Youth Orchestra.

In 1985, Keith became a founding member of the Australian String Quartet, based in Adelaide. He held the position for sixteen years, performing with the ASQ in many countries. Additionally, he travelled widely throughout Australia and made numerous recordings.

As well, Keith has conducted concerts and recordings with the Tasmanian and Adelaide Symphony Orchestras. He has also been conductor of the Australian Youth Orchestra’s Young Symphonists and tutor in the Australian Youth Orchestra’s Young Australian Concert Artists program on many occasions. He has attended numerous National Music Camps as tutor and conductor and now divides his time between teaching, performing and conducting.

In 2003, Keith took up the position of artistic director and conductor of the Adelaide Youth Orchestra. In 2004 he was awarded the University of Adelaide’s Stephen Cole Prize for excellence in teaching and, in 2006, was appointed Adjunct Professor in Strings and Chamber Music at the University of Tasmania.

In 2008, Keith Crellin was awarded the Order of Australia medal for his contribution to music and education.
