Richard Strauss (1864-1949) Also sprach Zarathustra The music is in no way a musical translation of Nietzsche's controversial theories about the übermensch. Richard Strauss saw the positive sides of the author's message: the demand for freedom, the longing for a better world, the power of action. The descriptions of nature were the most important source of inspiration. The extensive orchestral poem breaks up into nine sections, whose titles correspond to the names of the chapters in the book (but not always in the same order). Between these there are only three general pauses, the rest is in one go. As a motto he placed Nietzsche's "ode to the sun" with the call that "Too long have we dreamed of music, let us now wake up. We were sleepwalkers, let us now go out into the day..." The whole work begins with the sunrise: after long, grinding and very low C in double basses, double bassoon and organ, the sun breaks out in the notes C, G and C2. This is probably the most brilliant sunrise in the entire history of music, and just like Ligeti's music, it became the motif in the film 2001 – A Space Odyssey. The following parts have the titles: "About the inhabitants of the afterlife", "About the great longing" and "About the joy and passions", where the oboe intones a mournful melody. It is the dreams of youth that are buried. "The Night Wanderer's Song" is a heartbreaking farewell song where the description of nature returns in a reconciling C major in the basses. In the music, C major represents man and nature, while B major represents the universe - two keys that are very far apart. Neither of them emerges victorious from the battle at the end of the piece.
