He was one of the most inspiring pianists of the twentieth century. His remarkable personality as a unique artist was perfectly reflected in all his compositions. Sergei Rachmaninoff charcterized the last Romantic piano tradition with his charming, lyric and expressive playing and creative interpretations.
A virtuoso technique, rhythmic precision, colorful tone, polyphonic clarity of inner voices, incomparable sense of lyricism, accurate interpretation of different musical styles, force of expression through every detail of a composition: Rachmaninoff was in absolute possession of all these peculiar “instruments” for his performing.
The great charisma of this pianist came through especially when he played his own works. Due to his personal composing style, which was first influenced by Tschaikovsky, he further developed a contrapuntal writing and a distinguished variety in the chromatic harmonic structure, both deriving from Bach and Chopin.
He certainly dedicated a profound study, work and way of musical thinking from those great composers, becoming idiosyncratic when he created his own music.

It is known that Rachmaninoff suffered from a severe depression, caused by a breakdown after the premiere of his First Symphony. An unproductive period of about three years stressed him that much, but finally he recovered through a hypnotic therapy by the psychologist Nikolai Dahl. He was able to compose again and he wrote his gorgeous Second Piano Concerto, which was dedicated to his therapist. He recovered from that deep psychological crisis, finally being successful with the premiere of the Concerto.

Nevertheless a sort of darkness characterized the soul of his following works. Even his playing changed and became the idealized source of sadness of his inner being.
Probably because of his emotional power Rachmaninoff´s music has been often criticized by puristic tendencies, reduced just into sentimental patterns.
Of course we would face his works on the wrong side when accepting this theory, rather a deep understanding of his personality and his highly-structured music would bring us to a more faithful interpretation of the great composer.
In conclusion, Rachmaninoff remains an Immortal in the universe of great pianists.
