Heut triumphieret Gottes Sohn (I) in D minor, BWV 630

The Orgelbüchlein (Little Organ Book) BWV 599−644 is a set of 45 chorale preludes for organ — one of them is given in two versions — by Johann Sebastian Bach. All but three were written between 1708 and 1717 when Bach served as organist to the ducal court in Weimar; the remainder and a short two-bar fragment came no earlier than 1726, after the composer’s appointment as cantor at the Thomasschule in Leipzig.
