Droneo is an iOS music app that allows one to experiment with intervals. In this case I use a selected group of JI intervals I found interesting and change the chords over time. The program slows changes the chords from left to right and back. There are two versions of the same piece. One as straight out of Droneo and another where I used Cakewalks audio to midi conversion to provide events for percussion ensemble and effects. I apologize for the news banner sound that pops up in the middle of the performance.
