A small town (population 385 in the 2020 census) in northeast Iowa, and today’s morning name. I have never been to Spillville, but in my world it’s a famous place, and when the name came into my head on awakening, I knew exactly why: as I came to consciousness, my Apple Music had just been playing Dvořák’s String Quartet in F, Op. 96 (“American”), so of course Spillville came to mind; it’s almost as good a Spillville trigger as his Symphony No. 9 in E minor (“From the New World”).
I will explain. Meanwhile, let me recommend the Wikipedia article on Dvořák, for its detailed telling of a remarkable life, of great talent, a lot of pluck, a fair amount of luck, generous humanity, and the benefit of champions, advocates on your behalf (in this case, primarily Johannes Brahms).
