Atah Ehad
The classification of traditional Ashkenazi melodies into clearly defined genres is a difficult, perhaps impossible task, since the same melody can function as a liturgical melody, a zemer for the Sabbath, a Hassidic niggun and a Yiddish folksong. In addition, some Ashkenazi tunes were reincarnated as Zionist songs, becoming Israeli folk songs and folk dances in both secular and religious contexts.
