On my way down from the green room, I came up with an edge case idea. Literally five minutes before the performance, I pulled out my phone and ssh’d into the computer cluster to test my code (thanks Terminus!). It did not pass. I went on stage and performed Elgar’s Land of Hope and Glory from “Coronation Ode”.
During the next piece, which was orchestra only, I ran through possible solutions in my head. After performing Bernstein’s Celebrations from “Mass”, my ideas were solidified. On my way back to the green room, I continued to make the minor update and ran the edge case again. It worked!
