An organ fantasia based on this piece, Opus 27, was a breakthrough work for Max Reger (“RAY-guh”). This piece’s opening rhythm “pickup quarter, half half, half quarter, half quarter, half, half” is often replaced with a 4/4 isometric version. Oboe and continuo play this piece as a cantus firmus under a vocal diminution of it, in fugue, to begin Bach’s first posthumously published cantata. A mostly descending C major scale on the words “the kingdom is ours forever” ends this piece, which opens on the melody (*) “C C C, G A B, C B A, G.” (10[1])Raoul’s feast is interrupted by this piece, which the title group sings to their death, in Meyerbeer’s (10[1])Les Huguenots. The last movement of Mendelssohn’s Reformation Symphony is based on this piece (10[1])to honor the German princes who sang it at the Augsburg Confession. For 10 points, name this Martin Luther hymn whose title alludes (10[1])to God (10[1])as “defense and weapon.” ■END■ (10[1])
