The category of secular Jewish music is as elusive as it is important. It may be broadly defined as any music used primarily by Jews in non-liturgical contexts, and also includes Sephardic and Ashkenazic music.
The rhythm of Jewish life is determined by its calendar. Jewish existence is given structure and meaning by the passage of time. There are rituals, celebrations, and holidays that are observed on a daily, weekly, monthly, and yearly basis.
