my latest blog post, which is quite niche but is a process I wish I had known about earlier in researching American folk music (in my case, obviously #klezmer, but the same process could be used for a lot of genres). hope it helps someone in their research at some point. I used Ukrainian-American fiddler Pawlo Humeniuk as an example because he rules.
