the piece and again in retirement when reflecting on his career. Today, many commentators prefer to view Kullervo as a choral symphony, due to its deployment of sonata form in the first movement, its thematic unity, and the presence of recurring material across movements. Such a perspective conceptualizes Kullervo as Sibelius's "Symphony No. 0" and thereby expands his completed contributions to the symphonic canon from seven to eight. Kullervo has been recorded many times, with Paavo Berglund and the Bournemouth Symphony Orchestra having made the world premiere studio recording in 1970. A typical performance lasts about 70–75 minutes, making it the longest composition in Sibelius's . History Premiere Preparations for a work as massive as Sibelius's Kullervo stretched Helsinki's musical resources to the limit: the copyists labored to write out the parts, while organizers hired extra musicians because the Helsinki Orchestral Association then consisted of just thirty-eight permanent members. Moreover, the city had no professional chorus, and so about forty amateur vocalists were cobbled together from the University Chorus and the Helsinki Parish Clerk and Organ School's student choir. The rehearsals were also a challenge: the musicians, the majority of whom were Germans, not only viewed Sibelius as a neophyte but also had little understanding of the national heritage upon which Kullervo drew—a few of them even laughed derisively when they saw their parts and when the soloists sang. Speaking a mix of Finnish, Swedish, and German as needed, Sibelius gradually won over his performers through the force of his personality; as one vocalist recalled, "We doubted that we could learn our parts ... [but] the young composer himself would come and hold special rehearsals with us. This raised our self-esteem. And he came. His eyes were ablaze! It was that inspirational fire of which the poets speak". Kullervo premiered on 28 April 1892 at a sold-out concert audience in the Ceremonial Hall of the Imperial Alexander's University of Finland, Sibelius—initially pale and trembling—conducting. The soloists were the Finnish mezzo-soprano Emmy Achté and baritone Abraham Ojanperä. The audience—a mix of the regular concert-going public and patriots there for the nationalist spectacle—received two leaflets: first, a Swedish-language program that described Kullervo as a "symphonic poem" (""); and second, text in Finnish, (with a Swedish translation) from The Kalevala for Movements III and V, as well as a motto that helped it to contextualize the instrumental Movement IV. Notably, this was the
