K.Szymanowski is considered one the most prominent Polish composers after Chopin, whose influence Szymanowski himself always emphasized. A multitalented personality, he was a pianist, poet and writer. He was also a renowned teacher, director and reformer of the Warsaw Conservatory of Music. He toured Vienna, Germany, Italy, North Africa, France and the USA, travels which influenced his compositions. He died of tuberculosis at the age of 55 in Lausanne, where a bronze bust of the great man has recently been inaugurated. The Sonata for Violin and Piano op. 9 was composed in 1905 and first performed in 1909 by friends of the composer, Pawel Kochanski and Arthur Rubinstein. Written in Szymanowski’s « first period », it is lyrical and romantic in its first two movements, energetic and impetuous in the third. It allows musicians to express a whole range of emotions as well as technical ability.
