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.

Gerard Schwarz describes how Bela Bartok developed new rhythmic patterns modeled on Balkan and North African folk music and explored unusual instrumental colors and textures. During the 1920s and early 1930s, Bartok's innovative tendencies earned him a reputation as an uncompromising modernist, making him almost a musical anarchist who was unappreciated and largely unperformed, particularly in his native Hungary.

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.

Franz Liszt came of age with the flowering of the Romantic movement in literature and the arts, and the Romantic spirit had a profound impact on his development as both a man and an artist. Indeed, Liszt, like Berlioz, Wagner, and Chopin, gave expression to that spirit in both his life and his music. Liszt cut a larger-than-life figure, and everything he did tended towards extravagance.

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.

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.

Beginning in the waning years of the 19th century, Spanish composers turned to the rich tradition of Spanish folk music for materials and inspiration, and in doing so imbued their compositions with a colorful national character. The most brilliant of those composers was Manuel de Falla.

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.

Berlioz had a passionate and idealistic personality, one given to incandescent enthusiasms and uncompromising struggles. Through most of this career he stood in opposition to Paris' entrenched musical establishments, which looked on his innovations in harmony, form, and instrumentation with suspicion or outright indignation. The judgment that Berlioz was a wild-eyed radical contained a certain element of truth.

Gerard Schwarz takes you through the life of Anton Dvorak, a devoted Czech nationalist who, like other composers of the nineteenth century, brought national or ethnic pride into the concert hall by using their nation's folk music to evoke patriotic sentiments.

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.

Of the many remarkable violinist-composers Italy produced during the Baroque era, the most remarkable of all was Antonio Vivaldi. An artist of astonishing vigor and productivity (he wrote more than 450 concertos, 40 operas, and many solo, chamber, and vocal works over the course of his career), Vivaldi was one of the most innovative and influential musicians of his day.

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.

If the vivid expression of human passion is a hallmark of Romanticism in music, then Pyotr Ilyich Tchaikovsky was perhaps the most Romantic of all composers. A sensitive, introspective, and extremely emotional man, Tchaikovsky poured his joys, sorrows, and drams into compositions that have touched listeners for over a century.

The work of Ludwig van Beethoven (1770-1827) has been called the culmination of the Classical era or the wellspring of the Romantic era in European music. Historians today see him as the heir of Haydn and Mozart, carrying their musical discoveries to a new level of complexity and integration. But the generations of composers that followed Beethoven saw him more as the headstrong radical, breaking the shackles of classicism and showing new possibilities for music.
