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.

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]
