Thanks to the gramophone several of Rachmaninoff's compositions have been preserved in his own performances. However, it has been suggested in various sources that Rachmaninoff's style of piano playing underwent a dramatic change after 1917 that affected his sound and tempi. This suggestion fits in remarkably well with the image Soviet musicology wanted to create of a Rachmaninoff, who was supposedly unable to find peace and quiet for his art in a capitalist society. But is it true? Did Rachmaninoff's tempi change after 1917?
