Hymn #127: Lo, How a Rose E’er Blooming
EST IST EIN’ ROS is the name of this hymn tune, taken from the first line of the carol in German. Also called ROSA MYSTICA, this tune is believed to have its roots in Germany. For many years it was used primarily as a choral anthem because of its irregular meter.
This is a traditional German tune, thought to be from the sixteenth century. Michael Praetorius (1571-1621) arranged the tune for inclusion in the fourth volume of his Musae Sionae in 1609. Born on February 14, 1571, Praetorius died exactly fifty years later, on his birthday.
