 with a motif in which the woodwinds play an ascending A minor triad over the timpani. That motif is
 named "Alma's theme" after the wife of the composer and is heard again at the end of this symphony's
 final movement after the sound of three hammer blows representing fate. For 10 points, name this gloomy
