Johannes Brahms was a German composer and pianist. Born in Hamburg into a Lutheran family, Brahms spent much of his professional life in Vienna, Austria. His reputation and status as a composer is such that he is sometimes grouped with Johann Sebastian Bach and Ludwig van Beethoven as one of the "Three Bs" of music, a comment originally made by the nineteenth-century conductor Hans von Bülow.
Brahms composed for symphony orchestra, chamber ensembles, piano, organ, and voice and chorus. A virtuoso pianist, he premiered many of his own works. He worked with some of the leading performers of his time, including the pianist Clara Schumann and the violinist Joseph Joachim (the three were close friends). Many of his works have become staples of the modern concert repertoire. Brahms, an uncompromising perfectionist, destroyed some of his works and left others unpublished.
Brahms has been considered, by his contemporaries and by later writers, as both a traditionalist and an innovator. His music is firmly rooted in the structures and compositional techniques of the Classical masters. While many contemporaries found his music too academic, his contribution and craftsmanship have been admired by subsequent figures as diverse as Arnold Schoenberg and Edward Elgar. The diligent, highly constructed nature of Brahms's works was a starting point and an inspiration for a generation of composers. Within his meticulous structures is embedded, however, a highly romantic nature.

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.
