Wagner's Ring

This study ranges more widely than any other that has been seen in recent decades.

Not only what is derived from medieval sources, but also what is excluded.

Deliberate changes are made to the medieval Sigurd to fashion Wagner's Siegfried.

Chapter and verse of Schopenhauer's philosophy explains as not done before.

Wagner's developing musical skill changed the dramatic structure over the 20 years of composition.
