We will examine five major musical works from the 17th to the 20th century: Orfeo (Monteverdi), Messiah (Handel), the Ninth Symphony (Beethoven), the Symphonie fantastique (Berlioz), and Le Sacre du printemps (Stravinsky). Using Thomas Kelly's book First Nights, recordings of modern performances, and selected readings, we will study how these works function as pieces of music and what makes them unique.
