text: By 1900, Rachmaninoff had become so self-critical that, despite numerous attempts, composing had become near impossible. His aunt then suggested professional help, having received successful treatment from a family friend, physician and amateur musician Nikolai Dahl, to which Rachmaninoff agreed without resistance. Between January and April 1900, Rachmaninoff underwent hypnotherapy and supportive therapy sessions with Dahl on a daily basis, specifically structured to improve his sleep patterns, mood, and appetite and reignite his desire to compose. That summer, Rachmaninoff felt that "new musical ideas began to stir" and successfully resumed composition. His first fully completed work, the Piano Concerto , was finished in April 1901; it is dedicated to Dahl. After the second and third movement premiered in December 1900 with Rachmaninoff as the soloist, the entire piece was first performed in 1901 and was enthusiastically received. The piece earned the composer a Glinka Award, the first of five awarded to him throughout his life, and a 500-ruble prize in 1904.
  Amid his professional career success, Rachmaninoff married Natalia Satina on 12 May 1902 after a three-year engagement. Because they were first cousins, the marriage was forbidden under a Canon law imposed by the Russian Orthodox Church; in addition, Rachmaninoff was not a regular church attendee and avoided confession, two things a priest would have had to confirm that he did in signing a marriage certificate. To circumvent the church's opposition, the couple used their military background and organised a small ceremony in a chapel in a Moscow suburb army barracks with Siloti and the cellist Anatoliy Brandukov as best men. They received the smaller of two houses at the Ivanovka estate as a present and went on a three-month honeymoon across Europe. Upon their return, they settled in Moscow, where Rachmaninoff resumed work as a music teacher at St. Catherine's Women's College and the Elizabeth Institute. By February 1903 he had completed his largest piano composition of his career at the time, the Variations on a Theme of Chopin (Op. 22). On 14 May 1903, the couple's first daughter, Irina Sergeyevna Rachmaninova, was born. During their summer break at Ivanovka, the family was struck with illness.
