I have been revisiting the music of Estonian composer Arvo Pärt recently, which I find very consoling. Back in 2014, Tom Huizenga (NPR) managed to secure an interview with Pärt, where he reflected on the use of space and silence in his work:

“[W]hen we speak about silence, we must keep in mind that it has two different wings, so to speak. Silence can be both that which is outside of us and that which is inside a person. The silence of our soul, which isn’t even affected by external distractions, is actually more crucial but more difficult to achieve.”
