The word "Alleluia" or "Hallelujah" (from Hebrew הללו יה), which literally means "Praise ye Yah" or "Praise Jah, you people", is used in different ways in Christian liturgies. "Praise Jah" is a short form of "Praise Yahweh", or of "praise ye Jehovah".

In the spelling "Alleluia", the term is used also to refer to a liturgical chant in which that word is combined with verses of Scripture, usually from the Psalms. This chant is commonly used before the proclamation of the Gospel.

The Hebrew word Halleluya as an expression of praise to God was preserved, untranslated, by the Early Christians as a superlative expression of thanksgiving, joy, and triumph. Thus it appears in the ancient Greek Liturgy of St. James, which is still used to this day by the Patriarch of Jerusalem and, in its Syriac recension is the prototype of that used by the Maronites. In the Liturgy of St. Mark, apparently the most ancient of all, we find this rubric: "Then follow Let us attend, the Apostle, and the Prologue of the Alleluia."—the "Apostle" is the usual ancient Eastern title for the Epistle reading, and the "Prologue of the Alleluia" would seem to be a prayer or verse before Alleluia was sung by the choir.

Leonard Norman Cohen, CC GOQ (born 21 September 1934) is a Canadian singer-songwriter, musician, poet, and novelist. His work often explores religion, isolation, sexuality, and interpersonal relationships. Cohen has been inducted into the American Rock and Roll Hall of Fame and both the Canadian Music Hall of Fame and the Canadian Songwriters Hall of Fame. He is also a Companion of the Order of Canada, the nation's highest civilian honour.

While giving the speech at Cohen's induction into the Rock and Roll Hall of Fame on 10 March 2008, Lou Reed described Cohen as belonging to the "highest and most influential echelon of songwriters."

Cohen was born on 21 September 1934 in Westmount, Montreal, Quebec, into a middle-class Jewish family. He attended Roslyn Elementary School. His mother, Marsha Klinitsky, of Lithuanian Jewish ancestry, emigrated from Lithuania while his great-grandfather emigrated from Poland. He grew up in Westmount on the Island of Montreal. His grandfather was Lyon Cohen, founding president of the Canadian Jewish Congress. His father, Nathan Cohen, who owned a substantial Montreal clothing store, died when Cohen was nine years old. On the topic of being a Kohen, Cohen has said that, "I had a very Messianic childhood." He told Richard Goldstein in 1967. "I was told I was a descendant of Aaron, the high priest." Cohen attended Westmount High School, beginning in 1948 where he was involved with the Student Council and studied music and poetry. He became especially interested in the poetry of Federico Garcia Lorca. As a teenager, he learned to play the guitar, and formed a country-folk group called the Buckskin Boys. Although he initially played a regular acoustic guitar as a teenager, he soon switched to playing a classical guitar after meeting a young Spanish flamenco guitar player who taught him "a few chords and some flamenco."
