Preludes is a multi-channel sound installation composed by Chris Cobilis, based on research into the evolution and purpose of music.
Speakers are mounted on lampposts at Claisebrook Cove, East Perth, and are triggered by motion sensors.
As visitors to the site reach these points, the work begins to play.
High Visibility, curated by Melissa McGrath, is a series of free artist prints that are distributed at Perth train station every Wednesday morning.
City of Perth Lord Mayor Lisa Scaffidi said there were many ways to experience art.
‘High Visibility and Preludes are two free, interesting and thought-provoking events that challenge the way people think about and interact with art,’ Ms Scaffidi said.
‘Preludes is an interactive sound installation, inviting people to ponder sound, music and its evolutionary significance.’ Preludes curator Chris Cobilis said he started work on the project in April this year.
‘The whole piece of music is 40 minutes, but as it stands in East Perth the work cannot be listened to the same way twice,’ Mr Cobilis said.
‘It was a huge relief that a passer-by understood what it was about and that it brought her joy.
‘My intention is really to make people think about music.’
The works will run until the end of this month.
