For a while now I had the idea of playing with a shimmer reverb, so I took this assignment as the opportunity to create a single harmony of overtones on a Solina that ran through the reverb, to hide as the central point. Then I added the parts before and after, where it builds towards the ground tone. Added some simple phased bass and some drums that glitch. After listening to it after some time, I also embedded some noise in the mid section because somehow it seemed to pop up in my head every time at that place.
Oh, and the track art is done by taking the spectrum of the midsection and turning it into a vortex with depth of field in Touchdesigner
