La música cristiana es de origen judío: la liturgia musical de la sinagoga, en particular el canto psalmódico de los judíos como unidad poética musical, fue un legado preciado transmitido del Israel antiguo al cristianismo primitivo, como forma de manifestar tanto a nivel personal como comunitario las creencias religiosas y la fe en Dios.
Beside an open door as I drew night
I heard sweet Mary sing a lullaby
She sang about the lambs at close of day
And rocked her tiny King among the hay
Across the air the silver sheep bell rang
The lambs are coming home, sweet Mary sang
Your star of gold
Your star of gold is shining in the sky
So sleep my little King, go lullaby
As I walked down the road at set of sun
The lambs were coming homeward one by one
I heard a sheep bell softly calling them
Along the little road to Bethlehem
To Bethlehem
