Aaron is an accomplished violist who has appeared regularly throughout the past decade as a casual with the West Australian Symphony Orchestra. As well as playing symphonic repertoire, he has performed in a number of highly successful fringe and festival shows, including the award winning City of Shadows, which went on to perform seasons in New York and Melbourne, and Barking Gecko's critically acclaimed production of Duck Death and the Tulip. In addition to this, Aaron has sung as a bass with the eclectic choir The Spooky Men of the West, played violin with Indian/jazz fusion group Nadis, and has had numerous conducting commitments. Amongst these he has been the musical director of the South Side Symphony Orchestra, has been a regular conductor with the Allegri Chamber Orchestra, and conducted the initial workshop in Adelaide of Cat Hope’s new noise opera Speechless. Aaron has also worked and toured extensively with the Decibel new music ensemble, both as a player and as a programmer of the group’s animated graphic notation software for the iPad.

While also having a keen interest in conducting, Aaron's main research is in the area of animated graphic score notation. He has developed the Decibel ScorePlayer app for the iPad: an app that allows for the network synchronised playback of such scores. He is continuing to work on further updates to this software, in the hopes of increasing its functionality while maintaining its stability.
