Written over a period of 18 years, Rachmaninov’s sets of Préludes are a mirror and a record of his compositional development. With so rich a variety of character, colour, texture and mood, no two préludes are fully alike, and differentiation of tempo and register ensures that each prélude’s character is clearly defined. The first eleven pieces were conceived by Rachmaninov as a single cycle, and their full-hearted Romanticism contrasts with the significantly more angular, modernistic Op. 32. Whether evoking ballad or bell toll, the exotic or folk influences, the Préludes stand in the great tradition of works by Bach and Chopin written in all 24 major and minor keys.
