The Power of Suggestion - And the Result!!

Dr. Anton Mesmer , an Austrian physician, lay groundwork in neurology which resulted in the development of hypnosis in Scotland.
Mesmer moved from Vienna to Paris, placed a piano in his new apartment, and on at least one occasion had a fellow by the name of Chopin perform for a small audience there.
A little over a half century later, a young composer, after early success, ran into a period of not being able to compose. Depression set in, and even thoughts of suicide began to appear.
Upon the insistence of friends, he decided to visit a clinical hypnotist by the name of Nikolai Dahl, who was well-known for his work in the relatively new process.
In 1900, this young composer spent about four months under treatment of clinical hypnosis with Dr. Dahl, who suggested to him that he would once again create music, and important music, and would not stop writing throughout his life.
Well, the result was more than successful. One of the works this young man wrote shortly after his treatment ended was his second piano concerto, which a century later remains one of the most popular works in this form.
This young composer, as it was suggested by Dahl, did indeed write much music of great power, extending the Romantic period forty three years into the twentieth century. Dahl was proven correct about his prognosis, and the composer dedicated this concerto to him.
The composer's name - Sergei Rachmaninoff.
