On this day in 1926, Walter Damrosch conducted the New York Symphony in the first performance of the last major orchestral work of Finnish composer Jean Sibelius—his symphonic tone poem "Tapiola." The title refers to an ancient Finnish forest god, Tapio, and the music suggests an ancient mystery culminating in a burst of terrifying savagery.

After receiving the score, Damrosch wrote this note of appreciation to the composer: "No one but a Norseman could have written this work. We were all enthralled by the dark pine forests and the shadowy gods and wood nymphs who dwell therein. The coda with its icy winds sweeping through the forest made us shiver." Today the commission fee Damrosch paid Sibelius for this orchestral masterpiece makes US shiver: Sibelius was paid only $400.

At this point in his career, Sibelius was afflicted by intense self-doubt. He wrote in his diary: "I have suffered because of 'Tapiola,'... was I really cut out for this sort of thing? Going downhill. Can't be alone. Drinking whiskey. Physically not strong enough for all this…"

For the next 30 years and more, Sibelius lived in retirement, drinking heavily, and though rumors persisted that he was still writing music, no scores were discovered after his death.
