Opinion in all parts of the world would agree that Rachmaninoff is the most complete of living masters of the instrument; his technique is comprehens… - Sergei Rachmaninoff

It is as a composer that his name will live longest. He was the last of the colourful Russian masters of the late 19th cent[ury], with their characteristic gift for long and broad melodies imbued with a resigned melancholy which is never long absent.

Technically he was highly gifted, but also severely limited. His music is well constructed and effective, but monotonous in texture, which consists in essence mainly of artificial and gushing tunes accompanied by a variety of figures derived from arpeggios. The enormous popular success some few of Rakhmaninoff's works had in his lifetime is not likely to last, and musicians never regarded it with much favour.

I can respect the artistic aim of a composer if he arrives at the so-called modern idiom after an intense period of preparation…Such composers know what they are doing when they break a law; they know what to react against, because they have had experience in the classical forms and style. Having mastered the rules, they know which can be violated and which should be obeyed. But, I am sorry to say, I have found too often that young composers plunge into the writing of experimental music with their school lessons only half learned. Too much radical music is sheer sham, for this very reason: its composer sets about revolutionizing the laws of music before he learned them himself.
