Mozart called it the king of the instruments, Schumann recommended to learn to play it to achieve more understanding about the power of music, most of the great composers played and wrote works for it. What makes the organ being so extremely apart of all other musical instruments and containing at the same time the power of expression of all these together?
At this point we could not fail to mention the great master Johann Sebastian Bach, who plays the leading role in the music history as an organist of unlimited abilities and as a supreme composer of works for all styles and musical forms. Bach set the fundament of harmonic, chromatic and highly developed contrapuntal structure in all kind of composition. Bach’s prolific attitude toward a great artistic expression led him to improve existing musical forms, creating an innovative way of composing through unfatiguing exploration of original patterns and models.

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.

Understanding the score: the precondition of musical interpretation
There are basically two types of musicians: the first ones declare their artistic Credo remaining true to the score, the others rather prefer to remain true to the musical masterwork. The first kind of musicians is strictly approaching the written notes. The score represents an indispensable fundament for the study and the examination of the composer´s work.
