Pyotr Il'yich Tchaikovsky (Russian: Пётр Ильич Чайковский) was a Russian composer of the Romantic era. While not part of the nationalistic music group known as "The Five", Tchaikovsky wrote music which was distinctly Russian: plangent, introspective, with modally-inflected melody and harmony.Tchaikovsky considered himself a professional composer. He felt his professionalism in combining skill and high standards in his musical works separated him from his colleagues in "The Five." He shared several of their ideals, including an emphasis on national character in music.
