Chad Gadya (Aramaic: חַד גַדְיָא chad gadya, "one little goat, or "one kid"; Hebrew: "גדי אחד gedi echad") is a playful cumulative song in Aramaic and Hebrew.It is sung at the end of the Passover Seder, the Jewish ritual feast that marks the beginning of the Jewish holiday of Passover. The melody may have its roots in Medieval German folk music.It first appeared in a Haggadah printed in Prague in 1590, which makes it the most recent inclusion in the traditional Passover seder liturgy.
