Copland's father had no musical interest. His mother, Sarah Mittenthal Copland, sang, played the piano, and arranged for music lessons for her children. Of his siblings, oldest brother Ralph was the most advanced musically, proficient on the violin. His sister Laurine had the strongest connection with Aaron; she gave him his first piano lessons, promoted his musical education, and supported him in his musical career. A student at the Metropolitan Opera School and a frequent opera-goer, Laurine also brought home libretti for Aaron to study. Copland attended Boys High School and in the summer went to various camps. Most of his early exposure to music was at Jewish weddings and ceremonies, and occasional family musicales.
