Hava Nagila is a Hebrew folk song that emerged in the early twentieth century, based on an older Hasidic melody with lyrics commonly credited to Abraham Zevi Idelsohn around 1918. The title translates as let us rejoice, and the song became a staple at Jewish weddings, bar and bat mitzvahs and other celebrations worldwide. Recorded by many artists in different styles, it spread far beyond its origins into films, sports arenas and online videos, where its rising tempo remains shorthand for joyful communal dancing.
