Rabbi Yitzchak Isaac Taub (in Hungarian: Taub Eizik Izsák) (1751–7th of Adar 2, March 21, 1821) was the rabbi of Nagykálló (in Yiddish Kalov), Hungary and the first Hassidic Rebbe in Hungary.
He was famous for composing the traditional Hungarian Hasidic tune "Szól a kakas már".
[1][2] Taub was discovered by Rabbi Leib Sarah's, a disciple of the Baal Shem Tov, who first met him when he was a small child and took him to Nikolsburg to learn with Rabbi Shmelke of Nikolsburg.
[3] He taught that the tunes he heard were really from the Holy Temple in Jerusalem, and were lost among the nations over the years, and he found them and returned them to the Jewish people.
He said that the proof that it was true was that the gentile who would teach him the song would forget it as soon as the rebbe learned it.
He was famous for composing the traditional Hungarian Hasidic tune Szól a kakas már.
Zöld erdőben, sík mezőben sétál egy madár.
Sárga lába, gyöngy a szárnya, engem oda vár.
Ha az Isten néked rendel, a tiéd leszek már!
„Jibone háMikdos, ir Cijajn tömálé,” akkor lesz az már.
„Mipné chátoénu golinu méárcénu,” azért nincs az már.]
Another famous song by the Kaliver Rebbe is Sírnak, rínak a bárányok – also in Hungarian.
