In 2015, at the 150th anniversary of Jean Sibelius' birth, research about his music and personality is more active than ever. Recent discoveries about the musical, literary, artistic, political, and social life around him have decisively widened the scope of scholarly discussion. As part of the anniversary celebrations, a great number of Sibelius scholars gathered in Hämeenlinna, his birth town, for a conference leading up to his birthday on December 8. This volume draws upon the most current achievements of Sibelius research. It brings together the diverse—and sometimes even divergent—viewpoints that emerged from this international meeting. These studies cover all of the genres in Sibelius' production: orchestral works, incidental music, piano and chamber music, and songs, including both well-known works and rarities, and even some fresh discoveries. The chapters in this book are also a welcome reminder of the manifold sources of inspiration: the music of his contemporaries, nature, literature, and visual art. The versatility of Sibelius' output, and the richness of his creative imagination are presented here to any reader interested to learn more about the music of the Finnish master.
