This nigun is attributed to the R’ Meir Shlomo Yanovsky, the Rebbe’s maternal grandfather, who was the rabbi of Nikolayiv. The beginning expresses bitter longing and the end expresses joyful hope. (#203 in Sefer Nigunim)
This Chassidic cantorial song was composed by Reb Aharon Charitonov, of Nikolayev Russia. The tune is set to the words of Tal Yasis, a prayer for dew recited during Pesach.
