Your very first stop on any investigation of Yiddish Song should be the pages of the Inside the Yiddish Folksong Project: an Analytical Approach to a Treasured Tradition. The authors have been learning, collecting, performing, studying, and sometimes writing Yiddish songs for decades. It’s an aging brain trust that wants to transmit its collective wisdom at this pivotal moment. This is an incredible resource, with video lessons, essays, and it’s own set of comprehensive resources to take you further.
