Proper Text: A New Song Be by Us Begun (Ein neues Lied wir heben an)
This tune, likely written by Luther himself in 1523, was in effect a preliminary experiment in the writing of new hymnody for the Lutheran Church. It follows the German bar form (AAB structure) and supports repeated stanzas, much like the tunes employed by German bards at the time for sharing news and stories.
The difference is in the final cadence. As pointed out in the entry on this hymn in Luther’s Works, the version in the Erfurt Enchiridion ends on the tonic, while that in the Geystliche gesangk Buchleyn ends on the dominant. It is the latter that has been chosen for the Free Lutheran Chorale-Book.
