In 1903, Sibelius spent much of his time in Helsinki where he indulged excessively in wining and dining, running up considerable bills in the restaurants. But he continued to compose, one of his major successes being "Valse triste", one of six pieces of incidental music he composed for his brother-in-law Arvid Järnefelt's play "Kuolema" (Death). Short of money, he sold the piece at a low price but it quickly gained considerable popularity not only in Finland but internationally. During his long stays in Helsinki, Sibelius's wife Aino frequently wrote to him, imploring him to return home but to no avail. Even after their fourth daughter, Katarina, was born, he continued to work away from home. Early in 1904, he finished his Violin Concerto but its first public performance on 8 February was not a success. It led to a revised, condensed version that was performed in Berlin the following year.
