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 psychotherapy 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-rouble prize in 1904.
