If you would open any biography of Franz Liszt, you would probably mostly read about his disquiet life as a piano virtuoso, his passionate love life, and the return to his catholic roots at the end of his life. Although all of this might be true, it only scratches the surface of his comprehensive musical personality. Liszt was a pianist, conductor, teacher and organiser, but above all he was a composer of a voluminous, capricious body of work. Even though his piano works formed his core business, he gave rise to the symphonic poem, got rid of the organ's stuffy appearance, and reinvigorated the oratorio. Moreover, with his piano transciptions of Bach's organ works and Berlioz's Symphonie Fantastique, he was an advocate of both old and new music.
Together with his son-in-law Richard Wagner, he was in the forefront of the Romantic movement and anticipated the musical revolutions of the early 20th century with his new composition techniques.

Claude Debussy was a French composer. He and Maurice Ravel were the most prominent figures associated with impressionist music, though Debussy disliked the term when applied to his compositions. He was made Chevalier of the Legion of Honour in 1903. He was among the most influential composers of the late 19th and early 20th centuries, and his use of non-traditional scales and chromaticism influenced many composers who followed.
Debussy's music is noted for its sensory content and frequent usage of non-traditional tonalities. The prominent French literary style of his period was known as Symbolism, and this movement directly inspired Debussy both as a composer and as an active cultural participant Among his most famous works are his Clair de Lune, his Three Nocturnes and his orchestral piece La Mer.

The Russian composer Mily Balakirev is currently primarily known as the leader of The Mighty Handful, a group of five Russian composers devoted to nationalistic music. He was the only member of the group who had received a decent musical education and imparted his musical beliefs to the others, which resulted in several works that established the reputations of both the group and the individual composers.
Balakirev himself was influenced by Mikhail Glinka, whose style he developed and fused with Romantic compositional techniques. His oeuvre consists mainly of collections of folk songs and piano works, but also contains symphonies, overtures and symphonic poems. Through his leadership and he works, he became an important figure in Russian music history that helped to set the course for songs and orchestral music.
Balakirev often worked on his compositions for years, which deprived him of the credit for their musical inventiveness, which was instead attributed to Rimsky-Korsakov or Borodin, who appropriated his ideas. Another consequence of the protracted composition of his works was that they were less successful than they could have been if they had been completed earlier, since they were not that refreshing anymore when they were introduced much later.

Tchaikovsky is considered as one of the most talented Russian composers of the 19th century. Unlike many other Russian composers of his time, he studied at a conservatory and made the western music theory his own. So, he was not as distrustful of western music as the group of nationalistic composers surrounding Balakirev. Yet, Tchaikovsky sought to express the typical Russian mentality just as much and used many Russian folk songs in his music. He had a good relationship with Balakirev, who helped him with constructive feedback on his first masterpiece, the overture of Romeo and Juliet. At times, Tchaikovsky was emotionally unstable, which has often been attributed to struggles with his homosexuality. His decision to marry proved to be disastrous and plunged him into a deep crisis. Yet, the passionate letters of his fiance, even though they barely knew each other, did inspire him to compose his succesful opera Evgenij Onegin. Tchaikovsky had the wonderful gift of composing the most beautiful, lyric melodies. He had a feeling for creating a certain atmosphere in his music and mastered the art of orchestration. Moreover, he excelled in dance music, which made him the ideal composer for ballet. With his ballets The Swan Lake, The Sleeping Beauty, and The Nutcracker he brought the genre to a higher level. During his life, he was already a celebrity. He often did tours to conduct his music and in the USA he was welcomed as a star. He died unexpectedly, nine days after the premiere of his incredibly gloomy Sixth Symphony, probably of cholera. Some other highlights of his body of works are his First Piano Concerto, his Violin Concerto and the Rococo-variations.
