If you ever wonder how Sibelius’ music seems to come in two styles, one bardic, noble, warmly patriotic and slightly thumpy; the other austere, cerebral, craggy and interplanetary, think Karelia. This is the eastern portion of Finland near the White Sea, where ancient forms of native song and poetry still obtained at the turn of the last century. As Vaughan Williams scoured England for folksong and Bartók transcribed them in Hungary, a similar romantic enthusiasm for Finnish roots swept young Finns of the day. Karelianism, it was called, and Sibelius’ suite derives from the music he wrote for the Karelia Pageant of 1893, which represented something of a culmination of the movement. The opening “Intermezzo”, otherwise a contradiction in terms, was in fact used to separate two tableaux within the festivities.
