The Rizhiner Niggun

A melody carried from the court of Israel Friedman of Ruzhyn, the Hasidic rebbe who kept a palace, a carriage and silver, and was jailed by the Tsar.

A niggun travels the way a story travels: by being sung by someone who heard it from someone. This is the transmission mechanism the wing keeps pointing at — no score, no composer credit, a court and then a diaspora and then a recording. Shlomo Carlebach is the twentieth-century end of that chain, and how he is heard is contested; see the node that says so.
