The synthesizer theme emphasizes the sevenths and ninths of the chords. This orchestral music contains extensive chromaticism, diminished sevenths, and augmented scales. For example, triads and sevenths teach how to play chords with accuracy and speed. It is "minor" because it is the smaller of the two sevenths, spanning ten semitones. The harmony is based on sequences of diminished sevenths, which are often not resolved. The piece opens with the major sevenths being given out in snarls of muted brass. Later in the sevenths Crusade, it was taken back by the Catholics once again.
