The Classic Sounds Orchestra is a relatively young group that formed in 2006, the CSO has humble beginnings, rehearsing once a fortnight inside the shop of Classic Sounds.

In 2012, this group became formally incorporated. In 2015, having completed its first Business Plan, the Association now supports five rehearsing groups of diverse age groups and abilities.

A special culture exists in this organisation including one that nurtures family values. Flexibility with life needs (such as not always being able to attend rehearsals) and a philosophy that music groups should be ability specific and that age has no boundary. This also leads to the opportunity for experienced musicians to mentor those less experienced.

The CSO Association has given educational concerts called Meet the Instruments, and involves itself with the community in events such as giving recitals at the Kelmscott Anglican Church featuring the recently restored and oldest working Pipe Organ in Australia.

The group has given many outdoor and indoor concerts. To particularly enrich cultural exposure for its members, it intends to venture to Country WA as well as interstate, in the coming years.

The most recent community collaborations include the inaugural Performing Arts Festival where choirs from Pioneer Village School, Sacred Heart Primary, and Southern Hills Christian College provided a musical extravaganza with CSO in August 2014. To include all members of the ensembles that are part of the Classic Sounds Orchestra Association Inc., the Christmas season saw musicians fill the stage of the Gosnells Anglican Church for their Christmas service.
