World premiere of Sibelius's tone poem Tapiola.

Jean Sibelius was a Finnish composer of the late Romantic and early modern periods. He is widely regarded as his country's greatest composer, and his music is often credited with having helped Finland develop a stronger national identity when the country was struggling from several attempts at Russification in the late 19th century.

Tapiola, Op. 112, is a tone poem by the Finnish composer Jean Sibelius, written in 1926 on a commission from Walter Damrosch for the New York Symphony Society. Tapiola portrays Tapio, the animating forest spirit mentioned throughout the Kalevala. It was premiered by Damrosch on 26 December 1926.

December 26 is the 360th day of the year in the Gregorian calendar; five days remain until the end of the year.
