Hava Nagila is a traditional Jewish folk song whose Hebrew title means let us rejoice. Its melody comes from a Hasidic nigun, and Hebrew lyrics were written by musicologist Avraham Zvi Idelsohn in 1918. The song spread through Jewish celebrations around the world and became a staple at weddings and bar and bat mitzvahs, often danced to in a circle as the hora. Recordings by many artists helped it cross into wider popular culture, and short clips now circulate online for festive and humorous edits.
