Lieder

Strauss was a prolific composer of lieder. He often composed them with the voice of his wife in mind. His lieder were written for voice and piano, and he orchestrated several of them after the fact. In 1894–1895, around the age of 30, he published several well-known songs including " Ruhe, meine Seele! ", " Cäcilie ", " Morgen! ", " Heimliche Aufforderung ", and " Traum durch die Dämmerung ". In 1918, after a long hiatus devoted to opera, he wrote Sechs Lieder, Op. 68, also called Brentano Lieder. He completed his works in the genre in 1948 with Four Last Songs for soprano and orchestra. He reportedly composed these with Kirsten Flagstad in mind and she gave the first performance, which was recorded. Strauss's songs have always been popular with audiences and performers, and are generally considered by musicologists—along with many of his other compositions—to be masterpieces.
