The author examines the Wagnerian lyric drama as a regenerator of opera, tracing musical and theatrical prototypes from Greek tragedy and the Florentine lyric reform, and arguing music serves dramatic expression rather than an end in itself. He analyzes Wagner's structural devices—characteristic phrases and leitmotifs, orchestration, choral function, tonal procedure—and their ethical and formal roles. Dedicated chapters dissect Tristan und Isolde's chromatic longing, musical exposition, and fatal symbolism, and Die Meistersinger's comic debate between spontaneous poetic impulse and pedantic form. Throughout, musical examples and score illustrations support close readings of dramatic technique, thematic development, and musical language.
