Wieniawski was a Polish composer. Even though he came from a jewish family, his father converted to catholocism. Wieniawski's violin talent was quickly discovere, in 1843 he attended the conservatory of Paris at the age of 8. After he graduated, Wieniawski went on tour giving many recitals. He was often accompanied by his brother, Józef. In 1847, he published his first work, the Grand Caprice Fantastique.

On invitation by Anton Rubinstein, Wieniawski moved to St. Petersburg where he stayed until 1872. There, he taught a large number of violin students, led the Russian Musical Society's orchestra and string quartet. Fro, 1872 to 1874, Wieniawski toured throughout the United States together with Rubinstein and in 1875, he replaced Henri Vieuxtemps as a violin teacher at the conservatory of Brussels. In Brussels, his health declined fast, which at one time forced him to stop a performance midway through. He gave his farewell concert in 1879. A year later he died from a heart attack in Moscow.

Joseph Maurice Ravel was a French composer who is often associated with impressionism along with his elder contemporary Claude Debussy, although both composers rejected the term. In the 1920s and 1930s Ravel was internationally regarded as France's greatest living composer.
Born to a music-loving family, Ravel attended France's premier music college, the Paris Conservatoire; he was not well regarded by its conservative establishment, whose biased treatment of him caused a scandal. After leaving the Conservatoire Ravel found his own way as a composer, developing a style of great clarity, incorporating elements of baroque, neoclassicism and, in his later works, jazz. He liked to experiment with musical form, as in his best-known work, Boléro (1928), in which repetition takes the place of development. He made some orchestral arrangements of other composers' music, of which his 1922 version of Mussorgsky's Pictures at an Exhibition is the best known.
As a slow and painstaking worker, Ravel composed fewer pieces than many of his contemporaries. Among his works to enter the repertoire are pieces for piano, chamber music, two piano concertos, ballet music, two operas, and eight song cycles; he wrote no symphonies and only one religious work. Many of his works exist in two versions: a first, piano score and a later orchestration. Some of his piano music, such as Gaspard de la nuit (1908), is exceptionally difficult to play, and his complex orchestral works such as Daphnis et Chloé (1912) require skilful balance in performance.

Next to Arnold Schoenberg and Igor Stravinsky, Béla Bartók was a third seminal innovator of European art music at the start of the twentieth century. Bartók, too, sought a way out of the deadlock of tonal music around 1900, and he found it in folk music. Initially, he tied in with the nationalistic tradition of Franz Liszt with his tone poem Kossuth, but eventually he found his own voice with the rediscovery of the music of Hungarian peasants. Together with Zoltán Kodály he was one of the first to apply the results of folkloric research into his own compositions. One major difference between him and composers of the 19th century, was that Bartók did not adjust to the system of tonality, but created his own musical idiom from folk music. Because of this, his composition style was flexible to other musical trends, without having to violate his own view points. For example, his two Violin sonates come close to Schoenberg's free expressionism, and after 1926 his music started to show neoclassicistic tendencies, comparable to Stravinsky's music. Bartók was not just interested in Hungarian folk music, but could appreciate musical folklore from all of the Balkan, Turkey and North-Africa as well.

Igor Fyodorovich Stravinsky was a Russian composer, pianist, and conductor. He is widely considered one of the most important and influential composers of the 20th century.
Stravinsky's compositional career was notable for its stylistic diversity. He first achieved international fame with three ballets commissioned by the impresario Sergei Diaghilev and first performed in Paris by Diaghilev's Ballets Russes: The Firebird (1910), Petrushka (1911) and The Rite of Spring (1913). The last of these transformed the way in which subsequent composers thought about rhythmic structure and was largely responsible for Stravinsky's enduring reputation as a musical revolutionary who pushed the boundaries of musical design. His "Russian phase" which continued with works such as Renard, The Soldier's Tale and Les Noces, was followed in the 1920s by a period in which he turned to neoclassical music. The works from this period tended to make use of traditional musical forms (concerto grosso, fugue and symphony), drawing on earlier styles, especially from the 18th century. This style was often referred to as Neoclassicism. In the 1950s, Stravinsky adopted serial procedures. His compositions of this period shared traits with examples of his earlier output: rhythmic energy, the construction of extended melodic ideas out of a few two- or three-note cells and clarity of form, and of instrumentation.

Karol Szymanowski was a Polish composer and pianist, the most celebrated Polish composer of the early 20th century. He is considered a member of the late 19th-/early 20th-century modernist movement Young Poland and widely viewed as one of the greatest Polish composers.
The early works show the influence of the late Romantic German school as well as the early works of Alexander Scriabin, as exemplified by his Étude Op. 4 No. 3 and his first two symphonies. Later, he developed an impressionistic and partially atonal style, represented by such works as the Third Symphony and his Violin Concerto No. 1. His third period was influenced by the folk music of the Polish Górale people, including the ballet Harnasie, the Fourth Symphony, and his sets of Mazurkas for piano. King Roger, composed between 1918-1924, remains the most popular opera by Szymanowski. His other significant works include opera Hagith, Symphony No. 2, The Love Songs of Hafiz, and Stabat Mater.
He was awarded the highest national honors, including the Officer's Cross of the Order of Polonia Restituta, the Order of Merit of the Republic of Poland and other distinctions, both Polish and foreign.[1]
