I have a test where I am given the following article, what is an answer for the question: What is the full name of the symphony that caused a sensation when conducted by Erik Tuxen at the 1950 Edinburgh International Festival, sparking interest in Nielsen's music outside Scandinavia? ?  Nielsen is perhaps most closely associated outside Denmark with his six symphonies, written between 1892 and 1925. The works have much in common: they are all just over 30 minutes long, brass instruments are a key component of the orchestration, and they all exhibit unusual changes in tonality, which heighten the dramatic tension. From its opening bars, Symphony No. 1 (Op. 7, 1890–92), while reflecting the influence of Grieg and Brahms, shows Nielsen's individuality. In Symphony No. 2 (Op. 16, 1901–02), Nielsen embarks on the development of human character. Inspiration came from a painting in an inn depicting the four temperaments (choleric, phlegmatic, melancholic, and sanguine).The title of Symphony No. 3, Sinfonia Espansiva (Op. 27, 1910–11), is understood by the English composer Robert Simpson to refer to the "outward growth of the mind's scope". It fully exploits Nielsen's technique of confronting two keys at the same time and includes a peaceful section with soprano and baritone voices, singing a tune without words. Symphony No. 4, The Inextinguishable (Op. 29, 1914–16), written during World War I, is among the most frequently performed of the symphonies. In the last movement two sets of timpani are placed on opposite sides of the stage undertaking a kind of musical duel. Nielsen described the symphony as "the life force, the unquenchable will to live".Also frequently performed is the Symphony No. 5 (Op. 50, 1921–22), presenting another battle between the forces of order and chaos. A snare drummer is given the task of interrupting the orchestra, playing ad libitum and out of time, as if to destroy the music. Performed by the Danish Radio Symphony Orchestra conducted by Erik Tuxen at the 1950 Edinburgh International Festival, it caused a sensation, sparking interest in Nielsen's music outside Scandinavia. In Symphony No. 6 (without opus number), written 1924–25, and subtitled Sinfonia Semplice (Simple Symphony), the tonal language seems similar to that in Nielsen's other symphonies, but the symphony...
