Going into the obvious, I was wondering how to describe the singing style known as "white voice." Don't worry, you don't need to know what that sounds like. Here's some samples of white voice.
Full-register singing prizing volume and energy over ornament and modulation (not that the latter are wholly absent). The exultant cry of misty birch forests, chamois-haunted mountains, and bee-loud steppes. The last thing you hear after stealing turnips from Babushka's garden. On a side note it's kind of quaint to see somebody still promoting pan-slavism nowadays.
My worlds feel too dull and too much in my own head when I don't just follow these research rabbit holes. My recent story (still on the first draft so needs a lot of work), was read by someone who thought it was a historical fiction with some mythical elements instead of the straight up fantasy it actually was.
I used to listen to a lot of this music... your post has me digging up old favorites. This one feels a lot to me like an African-American spiritual. When I was young, there was no grief When I grew up, grief arrived Wherever I go, I find trouble With whom can I take counsel? - there is no truth in anyone I'll leave this world behind and go to a monastery There I will build a new cell A new cell with three windows Through the first I'll view the Danube river Through the second, I'll exult Through the third I'll weep
Not the Slavic people's fault, but that went over well in 1914. Regarding the music, one thing I noticed musically is they sing in unison a lot with a pretty heavy vibrato cutting through it. Almost like a whammy bar. Not understanding the language or knowing even they're even speaking words/phrases, I would say it's got a heavy chant vibe to it. Almost like scat singing, but not really. It's very cool, though.
