The Disquiet Junto this week asks for a composition drawn from a single tone.
At first I was challenged trying to think of a tone, then it took a few attempts to find one I liked.
After a day I settled on a video of my son playing a concrete marimba-like instrument outside the Questacon.
I explored pitching it and shifting the loops to play at various intervals, as well as gating the recording.
Before long I'd developed a simple melody that grew as loops joined it.
Below you can hear where the tone came from.
