As the 20th century winds to its close, Igor Stravinsky stands securely as its most important and influential composer. For more than six decades his works defined modernism in music, just as Picasso's canvases showed the essence of modernism in painting. Like that great Spanish artist, who was almost his exact contemporary, Stravinsky attained a dominating stature in his field. Only a handful of composers rivaled him in significance during his lifetime. None surpassed him.

Debussy was the first great composer of the twentieth century. He departed from previous musical practice to a greater extent than any previous composer. Though he completed his masterpieces Prelude to Afternoon of a Faun and the triptych Nocturnes before the turn of the century, it was not until 1902 that Debussy received widespread recognition.

Gerard Schwarz examines the life of this impolitic composer who lived in the political world of revolutionary Russia. Prokofiev's failure to interest himself in political realities, together with his tremendous confidence in his own genius, led him to ignore the darkening climate for artists in the Soviet Union. When the Soviets arrested his first wife on charges of spying, Prokofiev issued a public apology for his failure to write in an appropriate socialist style.

One of the great composers of the 19th century, Schumann wrote piano solos, chamber music, choral pieces and opera, dozens of superb songs, and some of the finest works in the orchestral reperotry. Much of this music conveys contented and even joyful sentiments; there is surprisingly little darkness in Schumann's compositions. Yet from the beginning of his career, Schumann was plagued by irrational fears and melancholy. In the end, his personal demons overwhelmed him.

The more adventurous composers of the 19th century, such as Liszt, Chopin, and Berlioz, made use of the Classical forms and procedures, though often modifying them for their own purposes. And certain composers remained dedicated to the Classical heritage. None was more devoted to this than Johannes Brahms.

Gerard Schwarz explains how Chopin came to embody the Romantic Movement with his rich harmonic shadings, his intense poetic expression, and his attention to the sensual qualities of music. But Chopin did more than just write music imbued with the spirit of Romanticism. In many ways he embodied an archetypal Romantic character: a lonely genius, doomed by that most Romantic disease, tuberculosis; a visionary musician too refined to seek public acclaim.

Felix Mendelssohn grew up in an extraordinary family, one distinguished by both worldly success and intellectual achievement. Mendelssohn was, in fact, the greatest child prodigy that music has known, undoubtedly helped by the early nurturing his talent received. Not even Mozart created such mature compositions at so early an age.

Like all tone poems, "Thus Spake Zarathustra" follows a "program" or story line which, to some extent, dictates its musical form and details. Strauss derived his program from Nietzsche's philosophical allegory or the same name which theorizes the rise of mankind from a primitive natural state to one of moral and intellectual superiority.

More than any other composer, Franz Joseph Haydn deserves to be called the father of music's "Classical" style. As he came of age in the mid-18th century, musical thinking was in the midst of profound changes. The compositional forms and procedures of the Baroque era began to seem old-fashioned and composers sought fresh modes of musical expression.

The music of Franz Schubert is cherished for its beautiful flow of melody; melody that runs through the composer's songs and instrumental compositions like a clear and inexhaustible stream. But Schubert was more than just a gifted melodist. He was also the creator of exquisite symphonies in the Classical tradition.
