Det sjungande trädet (opera) Det sjungande trädet (opera) Det sjungande trädet ("The Singing Tree") Op.110 is an opera in two acts by the Finnish composer Erik Bergman. The Swedish-language libretto, based on a Swedish fairy tale, was written by Bo Carpelan. The opera premiered on 3 September 1995 at the Helsinki Opera House. "Det sjungande trädet" was Bergman's only full-length opera and was composed between 1986 and 1988 as a commission from the Finnish National Opera. Prior to that, the closest he had come to the operatic genre was his 1971 "Samothrake" Op. 69, a 12-minute "musico-dramatic tableau" for speaker, mixed choir, and dancers.
