Alexander Alexandrovich Kopylov or Kopilov was an Imperial Russian composer and violinist. Kopylov studied for many years as a chorister and violinist in the Imperial Court Choir, where he would later teach for much of his life. (The Court Choir was modeled after the more famous one in Vienna, known today as the Vienna Boys Choir). He was unable to gain entrance to either of the major conservatories in Russia, but was nevertheless able to study composition privately with Nikolai Rimsky-Korsakov and Anatoly Liadov. Kopylov gained a reputation as a symphonist and composer of songs.
