was initially thought too young to study alongside his older brother Nikolai and a niece of the family. His insistence convinced Dürbach otherwise. By the age of six, he had become fluent in French and German. Tchaikovsky also became attached to the young woman; her affection for him was reportedly a counter to his mother's coldness and emotional distance from him, though others assert that the mother doted on her son. Dürbach saved much of Tchaikovsky's work from this period, including his earliest known compositions, and became a source of several childhood anecdotes. Tchaikovsky began piano lessons at age five. Precocious, within three years he had become as adept at reading sheet music as his teacher. His parents, initially supportive, hired a tutor, bought an orchestrion (a form of barrel organ that could imitate elaborate orchestral effects), and encouraged his piano study for both aesthetic and practical reasons. However, they decided in 1850 to send Tchaikovsky to the Imperial School of Jurisprudence in Saint Petersburg. They had both graduated from institutes in Saint Petersburg and the School of Jurisprudence, which mainly served the lesser nobility, and thought that this education would prepare Tchaikovsky for a career as a civil servant. Regardless of talent, the only musical careers available in Russia at that time—except for the affluent aristocracy—were as a teacher in an academy or as an instrumentalist in one of the Imperial Theaters. Both were considered on the lowest rank of the social ladder, with individuals in them enjoying no more rights than peasants. His father's income was also growing increasingly uncertain, so both parents may have wanted Tchaikovsky to become independent as soon as possible. As the minimum age for acceptance was 12 and Tchaikovsky was only 10 at the time, he was required to spend two years boarding at the Imperial School of Jurisprudence's preparatory school, from his family. Once those two years had passed, Tchaikovsky transferred to the Imperial School of Jurisprudence to begin a seven-year course of studies. Tchaikovsky's early separation from his mother caused an emotional trauma that lasted the rest of his life and was intensified by her death from cholera in 1854, when he was fourteen. The loss of his mother also prompted Tchaikovsky to make his first serious attempt at composition, a waltz in her memory. Tchaikovsky's father, who had also contracted cholera but recovered fully, sent him back to school immediately
