Traditional

"Hava Nagila" (lit. Let us rejoice) is a Hebrew folk song that has become a staple of band performers at Jewish weddings and Bar/Bat Mitzvahs. The melody was taken from an Ukrainian folk dance-song from Bukovina (a variant of Hora). It uses the Phrygian dominant scale, common in music of Romania and Western Ukraine. The commonly used text was probably composed by Abraham Zevi (Zvi) Idelsohn in 1918 to celebrate the British victory in Palestine during World War I as well as the Balfour Declaration. (Wikipedia)
