Quick Win #35

Reducing 4p-Structures to the OI

Here's a quick summary of the main takeaways from this Quick Win!

  • next to the OI (outside interval), you can also use the inner one and translate it into a line or pulse; this creates more transparency and interesting opportunities for the orchestration
  • you may also interlock the OI and the inner one later by using open harmony


Contrast is key, and this technique provides a lot of opportunities for creating contrast. You may distribute the OI and the inner one to different orchestral sections or even combine their harmonic purpose with a different function, like a motor or pulse.
