No edition in music is ever complete.
This Saturday in Helsinki, the YL Male Choir will premiere two pieces by Sibelius. The scores have been found on a sheep farm belonging to a family called Rautavaara.
Apparently they were given by Sibelius to one of the authors of Finland’s declaration of independence. One score is the original, longer version of “Terve Kuu!”, written in 1901. The other is “Suomenmaa” (1898) a melody re-used by Sibelius in Op. 28. Nobody seems to have known of their existence.
