sentences:  The idea for "L'enfance" went back to 1850 when Berlioz composed an organ piece for his friend Joseph-Louis Duc, called "L'adieu des bergers" ("The Shepherds' Farewell").He soon turned it into a choral movement for the shepherds saying goodbye to the baby Jesus as he leaves Bethlehem for Egypt.Berlioz had the chorus performed as a hoax on 12 November 1850, passing it off as the work of an imaginary 17th-century composer "Ducré".
