This piece was commissioned and titled by Tim Walters.
This piece has two instruments – one uses the Ringz Ugen in SuperCollider and the other is a Sine wave which is phase modulated by another sine wave where both are tuned to the same frequency. It is in harmonic minor, tuned with the default just tuning.
Harmonic minor is known as “Mogen Ovos” to klezmer musicians. Rather than apply western harmony practice (except for the final cadence), every player is picking notes independently. The just tuning helps hold the notes in a key centre.
