Sergei Vasilyevich Rachmaninoff(English: /rɑːxˈmɑːnəˌnɔːf, -ˌnɒf, rɑːk-/ rahkh-MAH-nə-nawf, -⁠nof, rahk-;Russian: Серге́й Васи́льевич Рахма́нинов, tr. Sergei Vasilyevich Rakhmaninov, IPA: [sʲɪrˈɡʲej vɐˈsʲilʲjɪvʲɪt͡ɕ rɐxˈmanʲɪnəf] (1 April [O.S. 20 March] 1873 – 28 March 1943) as a Russian composer, virtuoso pianist, and conductor of the late Romantic period. The influence of Tchaikovsky, Rimsky-Korsakov, Balakirev, Mussorgsky, and other Russian composers is seen in his early works, later giving way to a personal style notable for song-like melodicism, expressiveness and rich orchestral colours.

Born into a musical family, Rachmaninoff took up the piano at the age of four. He graduated from the Moscow Conservatory in 1892, having already composed several piano and orchestral pieces. In 1897, following the negative critical reaction to his Symphony No. 1, Rachmaninoff entered a four-year depression and composed little until successful supportive therapy allowed him to complete his enthusiastically received Piano Concerto No. 2 in 1901. In the course of the next sixteen years, Rachmaninoff conducted at the Bolshoi Theatre, relocated to Dresden, Germany, and toured the United States for the first time. Rachmaninoff often featured the piano in his compositions, and he explored the expressive possibilities of the instrument through his own skills as a pianist.

Following the Russian Revolution, Rachmaninoff and his family left Russia. They settled in New York City in 1918. With his main source of income coming from piano and conducting performances, demanding tour schedules led to a reduction in his time for composition. Between 1918 and 1943, he completed just six works, including the Rhapsody on a Theme of Paganini, Symphony No. 3, and Symphonic Dances. By 1942, his failing health led to his relocation to Beverly Hills, California. One month before his death from advanced melanoma, Rachmaninoff was granted American citizenship.

Gustav Mahler (German: [ˈmaːlɐ]; 7 July 1860 – 18 May 1911) was an Austro-Bohemian Romantic composer, and one of the leading conductors of his generation. As a composer he acted as a bridge between the 19th century Austro-German tradition and the modernism of the early 20th century. While in his lifetime his status as a conductor was established beyond question, his own music gained wide popularity only after periods of relative neglect, which included a ban on its performance in much of Europe during the Nazi era. After 1945 his compositions were rediscovered by a new generation of listeners; Mahler then became one of the most frequently performed and recorded of all composers, a position he has sustained into the 21st century. In 2016, a BBC Music Magazine survey of 151 conductors ranked three of his symphonies in the top ten symphonies of all time.[1]

Born in Bohemia (then part of the Austrian Empire) to Jewish parents of humble origins, the German-speaking Mahler displayed his musical gifts at an early age. After graduating from the Vienna Conservatory in 1878, he held a succession of conducting posts of rising importance in the opera houses of Europe, culminating in his appointment in 1897 as director of the Vienna Court Opera (Hofoper). During his ten years in Vienna, Mahler—who had converted to Catholicism to secure the post—experienced regular opposition and hostility from the anti-Semitic press. Nevertheless, his innovative productions and insistence on the highest performance standards ensured his reputation as one of the greatest of opera conductors, particularly as an interpreter of the stage works of Wagner, Mozart, and Tchaikovsky. Late in his life he was briefly director of New York’s Metropolitan Opera and the New York Philharmonic.

Mahler’s œuvre is relatively limited; for much of his life composing was necessarily a part-time activity while he earned his living as a conductor. Aside from early works such as a movement from a piano quartet composed when he was a student in Vienna, Mahler’s works are generally designed for large orchestral forces, symphonic choruses and operatic soloists. These works were frequently controversial when first performed, and several were slow to receive critical and popular approval; exceptions included his Second Symphony, Third Symphony, and the triumphant premiere of his Eighth Symphony in 1910. Some of Mahler’s immediate musical successors included the composers of the Second Viennese School, notably Arnold Schoenberg, Alban Berg and Anton Webern. Dmitri Shostakovich and Benjamin Britten are among later 20th-century composers who admired and were influenced by Mahler. The International Gustav Mahler Institute was established in 1955 to honour the composer’s life and achievements.
