Sonny Chua's music is characterised by its playfulness with styles and musical techniques. His music strives for the beauty of the simple and brevity and speaks in an accessible and lively language. As most of his music was primarily written as educational works for his students, these works were composed with attention to developing performance techniques and awareness of intelligent design.

Born on 2nd November 1967 in Penang, Malaysia, Chua grew up and was educated in Melbourne, Australia. He completed a Bachelor of Music degree at University of Melbourne with a focus on piano performance and music composition.

Chua's music is presently listed on all Australian examination syllabuses and is published by Allans Publishing and Midnight Editions. His piano works are regularly heard in competitions for young musicians and on the radio. He is currently President of the Association of Music Educators (Victoria) and Assistant Director of Music at Melbourne High School. Chua has an active interest in the research of boys and music education and is the director of the MHS Chorale, a voluntary based boys choir (members number over 60 students) at Melbourne High School. He is presently working in developing the repertoire for such choirs in schools and the community.

Chua has spoken on piano teaching and music education in workshops, festivals and conferences, including the 2003 Australasian Piano Pedagogy Conference, the 2004 Boys & Music symposium hosted by the Association of Music Educators (aMuse) the 2005 national conference of Australian Society of Music Education (ASME) and at the 2006 International Society of Music Education (ISME) world conference to be hosted in Kuala Lumpur. His papers on these topics have been published in conferences and educational publications.
