Born April 2, 1873, on the estate of Oneg in the province of Novgorod, Russia, Sergei Vassilyvitch Rachmaninoff was the fifth of the six children of Vassili and Lyoubov Boutakova Rachmaninoff. Rachmaninoff's aristocratic descent was traced to the Hospodars Dragosh, rulers of the realm of Molday from the fourteenth to the sixteenth century. One of the daughters from this family had married a son of the Grand Duke Ivan III of Moscow. The son's nephew was named Rachmanin, and from this source the family name originated.1 Rachmaninoff's mother was the daughter of a general, head of Araktcheyev Military College in Novgorod and the owner of a number of estates in the district. It was with a dowry of five of these estates that Lyoubov Boutakova married Vassili Rachmaninoff, and on one of these estates, Oneg, the couple settled down to married life.

Most of Domenico Scarlatti's harmonic progressions are quite orthodox when considered abstractly or free of their positioning in the score. The harmonic movement is given interest by subtle alterations in time; for example, (1) simultaneous upper and lower voices of different lengths, when repeated several times, change their relationship with each other; (2) one voice may be simply delayed so that it lags behind the other voice, thus combining to produce irregular harmonic sound on many succeeding beats; (3) the combination of two or more chords appearing on one beat is similar to number (2) but does not necessarily occur more than once.
