The Finnish Parliament signed a law concerning copyright for intellectual products on 1st August 1927. Consequently, Finland could join the Berne Convention the following year, which meant that Sibelius’s royalties for performances of his works began to be collected more efficiently. The year 1928 also saw the founding of Teosto, the Finnish Composers’ Copyright Society, which kept an eye on the payment of royalties to composers.

Sibelius had already received royalties from Germany and France through the German organisation GEMA. By the end of the 1920s he was on the way to becoming a wealthy man. The improved situation can be gathered, for example, from the costly roof repair at Ainola in 1932. Sibelius could have paid for the repair three times over, merely from the royalties accruing to him that year.

The copyright on musical works continues for 70 years after the composer’s death. In the case of Sibelius they will end in 2027.
