This calculation, made by Helsingin Sanomat, makes Sibelius, who died in 1957, the highest-earning Finnish composer in 2004. A spokesperson for Sibelius' beneficiaries did not wish to confirm the amount, however, because there are so many beneficiaries that no single one of them received a significant sum.
According to Teosto, the copyright society for Finnish composers, most of the royalties for Sibelius works come from outside of Finland. In 2003, the Sibelius works that earned the most outside of Finland were the Second Symphony and Violin Concerto.
The composer's heirs have registered the Sibelius brand, in order to continue copyright protection of the works beyond the standard 70 years after death.
