Hugo Emil Alfvén (May 1, 1872 – May 8, 1960) was a Swedish composer, conductor, violinist, and painter. Alfvén became known as one of Sweden's principal composers, together with Wilhelm Stenhammar. Alfvén's music is in a late-Romantic idiom. His orchestration is skillful and colorful, reminiscent of that of Richard Strauss. Like Strauss, Alfvén wrote a considerable amount of programmatic music. Some of Alfvén's music evokes the landscape of Sweden.
