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, (-5[1])C B A, G.” (-5[1])Raoul’s feast is interrupted by this piece, which the title group sings to their death, in Meyerbeer’s Les Huguenots. (10[1])The last movement of the (10[1])Mendelssohn’s Reformation (10[1])Symphony (10[4])is based on this (-5[1])piece (10[1])to honor the German princes who sang it at the Augsburg Confession. (10[1])For 10 points, name this Martin Luther hymn (10[1])whose title alludes to God as “defense and weapon.” (10[1])■END■ (10[2]0[1])
